2. Which one a better LCD PLASMA LED TV?

Led is your best. Plasma tv do not last long and lcd can look kinda goofy. Plus, once your plasma tv goes out, you have to pay more money just to have it taken away since you can just throw it away because it is hazardous liquid. Led is the way to go

3. How to clean LCD/ led tv screens without paying 20 bucks for water gel specialized formula?

A familiar question. See the link

4. What type of tv? LCD? PLasma? Whats the difference and which one has the least problems?

i am told that sizes up to 37 " recommend an lcd and above that plasma is better , but there are now LED tv,s about which i know nothing , so maybe one of them would suit ?

5. Do I need DHMI cables on my new HD LED TV?

This Site Might Help You. RE: Do I need DHMI cables on my new HD LED TV? Hi everyone! I have Comcast and subscribe to their HDTV. I just recently bought a 55" Toshiba HD LED TV. The problem is, the picture is no different on the HD channels than it is on the regular channels. I have checked all of the settings on the box using the Comcast Help feature and I...

6. Can someone tell me a reasonable excuse for cracking a led tv screen, so that the warranty will cover it?

just tell them it cracked for no reason at all. Its a manufacturers defect and when they investigate they will find that....unless your lying

7. Samsung led tv questions?

Any LCD or LED HDTV has a slow response time. Refresh rates of 120 hz. or more help the blur, but some also experience a 'lag' when using LCD/LED... Refresh rates can also mess up movie viewing unless turned off, especially with 24 FPS movies.

8. Which is better, LED TV's or Plasma TV's?

if you are going to be gaming alot with this tv i would recommend plasma if its just for general use i would go with the LED

9. which led tv is better?

The overall performance of the samsung is superior to the sharp. Now the sharp is a good tv. Your upgrade here is in size not quality. There is a reason that the 70" sharp is priced as low as it is. It does not compare to the samsund, it's not in the same class

How Do I Connect External Speakers to LED TV Having 3.5 Mm DVI/PC Port, a USB Port, HDMI Port, Compo
All of the options you've listed are *inputs* to the TV, not outputs. For external speakers you need an audio output connector of some type. On older sets it was a pair of red/white RCA jacks clearly labeled "out." That went to the line input of an external amplifier, like a home theater receiver or a surround sound amp. The speakers connect to the external amp, not to the TV. On newer sets, there is usually one of two types of digital audio output jacks, intended for connection to an external amp having a matching digital input jack. Again, the speakers connect only to the amp. If you want to update your question with your TV's make and model number, we can take a look an confirm what you have or do not have for external audio options. But nothing you've provided so far can do it.1. how to connect creative A520 5.1 speaker to sony LED tv?Thats wrong because I am able to connect my Samsung 7 series TV to Create A520. Its just that it only plays 2 channels i.e. 2 speakers and one Subwoofer. I tried connecting the same speakers to my external sound card of computer and all 5 speakers subwoofer works just perfectly.2. How can I get samsung led TV to work as importing it from uk to canada.?Well... your TV should work in the North America. In the user manual it does say that it supports NTSC-4.43, NTSC-3.58 (and various other standards). It also supports HDMI and PC inputs, so you could always use those in a pinch (see p58 of your manual for the specifications). That said, it wo not support North American power, so you will need a power converter to plug it in. Most power converters are designed for traveling and not for full time use. They are notoriously wasteful on electricity. You will probably pay for a new TV in a few years just on wasted power. For the trouble of this, you could easily just sell the TV in the UK for 300 ($400 or so) and buy a new 40" TV in Canada for about $550 -- or a used one for about half that.3. CRT, Plasma, LCD or LED TV? Which is the better for home use?Well I hate to say it but there are some CRT TVs that can produce a native 1080p very few where made. Also for best picture a CRT can not be beat. If you can find the high end computer monitors specifically Sonys trinitrons are best. A GDM FW900 Sony is probable the best in fact it can produce a native 4k picture and the last one was produced over 10 years ago. Also if your a gamer a crt can not be beat simply for the fact a lcd of even plasma dlp has lag to produce the image. If you look into it the big graphic companies that do CGI for movies like to use CRT monitors because the have infinite contrast something lcds etc will never be able to do.4. New LED TV Straining My Eyes Help?Get a calibration disk or use a Pixar movie and go to the disk setup menu on the Pixar disk. It will have simple test-patterns and instructions for properly setting the brightness, contrast and color. Eye strain can be caused by watching TV in a dark room or sitting too close or too far away. Search for "Viewing distance calculator" to find the optimal distance to sit.5. Can i play ps3 on a monitor with the same quality as a small led tv?Yes I have a samsung 37' and a 47' and a 19 hp monitor and my ps3 conected to it and it looks awesome its on my gaming room it looks better than the 47 it has great resolution I will be uploading gameplay from assassins creed 3 tomorrow you will see jow it looks I love my monitor visit my channel so you can see it.6. Can i play PC video games in 3D via 3D glasses with 3D LED TV with ATI HD5870?i see why not, but as long as the games have a 3d setting then it can be done, because some games do not allow 3d
Huaxing Optoelectronics Plans to Build an 11 Generation LCD OLED TV Manufacturing Plant, Which Will
On May 22, csot (a subsidiary of TCL) announced that it planned to build an 11 generation LCD OLED TV manufacturing plant in Shenzhen. The second 11th generation line of Huaxing optoelectronics project aims to invest in the construction of a monthly processing 3370mm & Tides in Guangming New Area, Shenzhen; The 11th generation ultra-high definition new display device production line with about 90000 2940mm glass substrates mainly produces and sells 65 inch, 70 inch and 75 inch 8K ultra-high definition displays and 65 inch OLED and 75 inch OLED displays. The total investment of the project is about 42.683 billion yuan. The project is jointly invested by TCL group, Huaxing optoelectronics and Shenzhen major industrial development fund. It is planned to officially realize mass production in March 2021.The latest news indicates that the new plant will adopt oxide TFT backplane, and the OLED business will also use 11th generation substrate (which may be cut into actual OLED front deposition). In the capacity of 90000 substrates per month, the OLED production line will use 20000. The plant will start mass production in 2021.It is reported that Huaxing optoelectronics is making progress in the inkjet project and cooperating with kateeva, Sumitomo chemical, Merck, DuPont and Tianma, as well as the scientific research teams of Chinese universities. It is unclear whether these groups have joined Guangdong Juhua printing and display technology company established by Huaxing optoelectronics and Tianma in 2016.Huaxing optoelectronics believes that the ink-jet printing technology of OLED TV will be available in the next 3-5 years, which means that it can be used in the new 11th generation factory, but the factory may adopt the evaporation process at the initial stage.At present, the production capacity of OLED panels is mainly controlled by Korean panel factories. Small and medium-sized OLEDs, represented by Samsung, mainly produce RGB OLEDs by high-temperature evaporation. At present, the process technology is relatively mature and the yield is high. Domestic panel factories have followed up with investment; In terms of large-size OLEDs, w-oleds are mainly produced by LGD through high-temperature evaporation. At present, the production cost is much higher than LCD TV panels, and the market acceptance is low. In 2017, 1.7 million OLED TV panels were shipped, accounting for less than 1% of the TV panel market. The scientific community seeks to break through the bottleneck of large-scale OLED mass production in other ways. Printing display is one of the high hopes.The printing display uses organic, inorganic and nano materials processed by soluble liquefaction, and uses printing or coating technology to replace the traditional semiconductor technology / vacuum technology to make the display. Compared with evaporated OLED, printed OLED has the characteristics of light, thin and flexible, large area, low cost and green manufacturing. It is a revolution of industrial technology and the development direction of new display industry in the future. Samsung in Korea, joled in Japan and Huaxing Optoelectronics in China are actively developing printing and display research and development, but Huaxing optoelectronics is the first enterprise in the world to invest in printing OLED panel production line.Industry experts predict that the printed display will reach the conditions for mass production in 2020. When the key technologies of printed display are mature and industrialized, the production cost of large screen OLED will be greatly reduced and the rapid development of large-size OLED panel market will be promoted.
Samsung Will Spend $11 Billion to Build a Factory That Can Produce Real QD OLED TV Screens
Samsung will close all its LCD production lines by the end of this year, including two in South Korea and two in China, Reuters reported. Samsung said that all previously signed orders will fulfill the delivery agreement before the end of the year, and partners don't have to worry.SamsungIt is reported that Samsung's move is not because of the problem of LCD screen sales, but to shift the focus of the display from LCD screen to QD OLED screen, because its subsequent development plan is to focus on the production of quantum TV, and the production of quantum TV needs QD OLED screen. It is also pointed out that Samsung made such a decision, on the one hand, because considering the recent downturn in the price of LCD screens around the world, consumers' demand for such screens is also gradually decreasing. On the other hand, we have to bear the pressure from Chinese competitors, because the LCD screens produced in China are occupying more and more market share. However, Samsung did not disclose to the outside world the real reason for its plan to stop producing LCD screens.Samsung TVIn addition, Samsung announced its latest plan to spend $11 billion to build a factory capable of producing real QD OLED TV screens. The factory uses the latest technology to make QD OLED screens instead of old technology. The new OLED has a service life of up to 1 million hours and is made of indium phosphide instead of toxic cadmium.
There Will Be More Innovation and Subversion in the Field of LED Display in the Future!
To be sure, innovation is the first driving force for the reform of LED display industry, and it will also be the subverter of the industry. Traditional LED display is subverted by special-shaped screen and small spacing. Cob opens a new era of packaging. Transparent screen and grid screen give more possibilities for outdoor wall display. Interactive large screen makes monotonous screen more life. These are subverted by "innovation"!Throughout the current industry, the technical development of LED display screen has entered a relatively mature stage. Whether it is the further optimization of small spacing or the emergence of cob and micro led, it has a relatively clear innovation and development direction. At the same time, manufacturers of LED display packaging, chips and supporting facilities in the industrial chain are also trying to improve the existing technology and process, and continue to pay more attention to and explore new technologies... The upgrading and transformation of the whole industry needs to be promoted by innovation.With the further improvement of the demand of the global display market, the market competition of LED display manufacturers has become more intense. In order to survive and develop, major display enterprises have made corresponding adjustments: those who deeply cultivate products, adjust development strategies, expand industrial scale, those who play cross-border, and those who accelerate to seize emerging markets... In this smoke filled "screen display war", only screen enterprises that adhere to the awareness of innovation can laugh to the end, while those who stick to the old rules, It is only sooner or later that screen enterprises that do not know how to keep up with the new trend of market demand will be subverted.However, from the current situation, except for a number of old "leading" screen enterprises in the industry and the newly rising "dark horse" screen enterprises in recent years, the innovation situation of other small and medium-sized screen enterprises is not optimistic. The fundamental reason is that there has been a great integration trend in the current industry, the advantageous resources are concentrated to the strong screen enterprises, and the weak screen enterprises have deficiencies in capital, technology, manufacturing, brand, channel and other aspects, so their innovation is more difficult.However, in this environment, there have been a number of small and medium-sized screen enterprises in the industry who have long adhered to innovation. They have found a suitable and persistent way in many innovation directions, such as the improvement of energy-saving and power-saving performance of LED display, the simplification of display installation and maintenance, the research and application of new materials for LED display box, and even the combination of LED display with VR, AR, 3D and other virtual technologies, Ar virtual fitting room under the concept of "human screen interaction", AR game paradise that adults and children are interested in, and so on. With the continuous improvement of intelligent LED display screen and the development of display creativity, LED display can surprise the audience in more fields. We sincerely hope that in the new era, we can continue to change our ideas, strengthen innovation and further realize the technological subversion of the industry.At present, under the development trend of continuous innovation of LED display technology and products, the application restrictions of LED display become smaller. Whether in the field of super large area display or small area close-up display, LED display shows certain feasibility and good application prospects. Moreover, with the acceleration of commercialization, digitization and intellectualization, the application blue ocean of LED display screen is also more magnificent. We look forward to more innovation and subversion in the field of LED display screen in the future!
In What Size Is OLED TV Going to Release?
According to CES-2012 the biggest size of OLED TV is 55", both LG and Samsung unveiled their TVs in this show and promised to bring it to the market till year end and I think it is much more bigger than normal 40-42" flat screen TVs1. What is the difference between 4K and OLED TV?As far as I am aware, the OLED is a TV with a curve to it. And the 4K TV just simply has 4 times the quality of a normal HDTV2. What is the exact weight of LG OLED TV which is about to come in next upcoming months?The 55 inch? 16.5 pounds. Any flat screen deserves a wall3. Can an OLED TV be transported flat?It isn't ideal since its more likely to get damaged, but it's possible if you have the original box with all of its inserts and styrofoam intact. Just make sure to be mindful of bumps on the road and that the TV is secured enough to not bounce around4. Which company currently has a very good handle on making OLED TV screens? With least risk of burn-in & retention, while still delivering amazing results.OLED or QLEDsThe best TVs right now if money is not an issue, or not a huge concern and you want a great TV are OLEDs and QLEDs.LG makes OLED panels for LG and Sony and every other companies because they have the patent. OLEDs are made with an organic compound that lights up, goes dark and changes color by themselves. This allows for very dark blacks and the OlEDs can be very thin. LG has a model that is so thin it is recommended it only be installed by an expert otherwise you can accidentally RIP YOUR TV!The disadvantage of OLEDs is organic things can die or adapt. This is called Burn Out: one pixel shots off or turns a color, hopefully not pink, and stays that way, Burn In is where a very bright image is onscreen to long, for example a channel logo in upper corner or paused sunset, and the pixels adapt and you get a white smear there. Samsung to avoid this, and surely to avoid paying LG for the patent makes QLEDs. Samsung makes a lot of TVs so they get their materials cheaper and do a lot of product testing. The QLED has the brightest pictures, which can be toned down by changing picture mode from Vivid to Cinema, I like Vivid for the computer correction and how it treats light so I leave it on but lower the brightness and color saturation slightly in Advanced Controls. This is very attractive and best for rooms with lots of light. They have computer controls to enhance the blacks which has brought the darks very close to OLEDs without the danger of an expensive TV getting Burn in or Burn out.I think with Sony you pay a premium for the name and the expensive Japanese economy. The best looking TV I have ever scene aesthetically is the Q6 curved. Some people think it makes things look 3D. Unfortunately, Samsung is the only manufacturer who still makes curved TVs and they don't make a full-array version.The Q8 is full array, what this means is behind the panel of pixels producing colors is another panel of LEDs that does an under painting of light, or mimics the lights and darks of the picture by turning on or off LEDs, so your brights are brighter and darks are darker.It's a whole different viewing experience. If you've seen Avatar you know the aliens have blue skin and wear leather outfits. On a QLED, they are actually blue with faint darker blue stripes, inside arms are lighter blue with little white energy points. Thanks in Avengers has fake pores in his nose. Unfortunately you see too much sometimes, Harrison's fords complection looks like someone is trying to flatten out tree bark with caked on make up.The Samsung also has voice controls with their own Bixby, that works great. It's the first voice controls I've had that actually works, so much better than my 2016 Ford Fusion which has voice controls but unfortunately doesn't understand anything I say and is very complicated.

Does HDR work on the PS4 for the Mi LED TV 4?No MI tv india does not support HDR. I tried with HDMI 2.0 and in playback setting there is no such option as HDMI. In PS4 it clearly mention as your Tv does not suppprt HDR5. What is the remote code for Samsung led tv for the ATT uverse remote control?Att Uverse Remote Codes6. Is vizio a good brand for led TV's?Only if you think Hyundai is a good brand for cars. In other words, its not ALWAYS bad. There are much better options out there. But if you cannot afford something nicer (FYI, you can always afford something nicer than a Vizio), than just make sure you invest in a protection plan7. Which LED TV brand is better, Sanyo or Vu?According to me, I will go with Vu because it costs less than sanyo and is more budget centric than sanyo. It gives 4k TVs for around 33000 rupees . Which is pretty cheap. But as a suggestion I will always recommend you to go with known brands like sony, Panasonic, sharp. Recently, Thomson also entered led tv market8. how do i install the stand of the 46 inch samsung LED TV?do not quite understand the question. but from my experience it's kind of like fit the pieces together if they mesh9.

This is less work than trying to convert the current can mounts to 4" round to mount the flat panels that are mounted by a crossbar in the outlet box. Flat panels do not need a can, but still needs feed outlet, either for power and some for the mounting point. Below is link to one brand/source that you can select the color temp, etc.Sample of Selection of color temp - LED FloodCan I connect my Samsung 32J4033 LED TV with my Android mobile phone by Wi-Fi or by Bluetooth?Yes you can, only if it is a smart TV.If its just a normal LED TV, then you cannot.You can make it smart though, by using either Google's Chromecast or Amazon's Fire TV stick and stream content on your TV, if that's what you want to do by connecting your android phone to the TV.Hope this answers it.Can I connect my Samsung 32J4033 LED TV with my Android mobile phone by Wi-Fi or by Bluetooth?.Adjusting LED currents same level for different voltage levelsThe smaller voltages would make it more difficult to light an LED with the same intensity using the method you talked about. I would probably use the different output voltages turn on N CH MOSFETS with very low Threshold voltages. Vdd should be 12 volts. Adjust your resistor values between the Cathode of LED and the Drain of MOSFET.LED light DROID 4You can use Light Flow to customize LED notifications; it also has a lite version.Light Flow allows you to take control of your notification LED colors and makes them successively flash one color after another.It also allows you to set repeating sounds on vibration patterns for you notifications. You can also set a "sleep" mode or "on charge" where the lights and/or sounds and vibrations will not be heard or seen.what kind of scientists study/create LED / OLED displays?Surely Electrical Engineers do this. But there are two types of Electrical Engineers. One who deal with power and the others who play with circuit design. Precisely , Circuit design professionals work with LES's or OLED's.Constant Current Square Wave through LEDWhy not use 1 side of an SN754410 Quad Half H-Bridge and ToneAC on the Arduino to drive the LED ?I am using this to drive 4 LED units, each 4.5V 54mA from my Arduino. My main power supply feeds a 7805 voltage regulator, and this supplies the Bridge. A diode on the output side drops the voltage to around 4.7V, and total current = 54 x 4 = 216mA.Do you think that the energy saved by using LED outweights the risk of lead?You will probably be delighted to hear that it is no longer much of an issue, as Lead (Pb) free LEDs are already in the marketplace (first link provided below), and several countries have already taken the lead in setting standards to eliminate LEDs containing lead already (second link). Arrangements should be made for the safe disposal of those which are in circulation, however they not that dangerous individually as they contain only very tiny amounts of lead usually in a sealed unit.Do LED lights get gradually dimmer as they age or just suddenly fail?Both failure modes occur. Generally more outright failures occur, due to cheaply designed power supplies that fail. But LEDs with simple power supplies just get dimmer with age. Sometimes power supply over voltages cause a premature failure of the LEDs, or heat build up will.Pi 3 not turning on red LED only lights up and the green LED lights up for 2 seconds before turning offThe number of times the green LED flashes indicates what the problem is:For Pi's running firmware before 20th October 2012:For newer firmware versions, so this will apply:I think the quickest fix is to backup anything important on the SD card. And try installing Raspbian again but on a different SD cardWhat happen if i connect the capacitors with few LED Strip in parallel?Yes, because they are in parallel. Which means that if the LED strips are different lengths, the voltage drop through each LED wo not be the same.No, the current through the capacitor will be higher so it will discharge faster. You could use a higher-value capacitor to compensate for this.Resistor calulation for two LEDI use two similar IR LEDs to send short RC code bursts without resistor without problems. If that#s your application then you should be fine. You may run into burned out LEDs, though, if the pin stays high for too long due to some issue.Do you absolutely need an LED or UV light for gelish/shellac nail polish?You would better use an LED or UV light for nail polish and the UV light will make your hands become black after you use for a long time and it will take more time if you use UV light ,so I suggest you use LED light. You can search led lights special for nail polish on website there will ba many kinds and you can choose oneHow do you like the Lg LED HX301G LG projector?First of all I have to say that I do not own one of these but I took a look at low budget LED before getting a standard lamp sourced projector. From what I understand, the HX301 can suit your needs but it has some serious drawbacks. It has quite a low resolution because a higher resolution LCD would block out too much light for the LED source to be useful. this means that image quality suffers because of both the low resolution and the low light output. None the less, if you can find a space that's dark enough, get a decent screen for it and do not care that much for high resolution movies people have achieved some very decent results. With the added benefit of functionally never needing to change any lamps. Check out some youtube videos for examples.Will LED lights ever be practical for home lighting?The guy who said they are a fire hazard was either a liar or an idiot. I have a mag flashlight with an LED. It is super bright. It's a blue shade of white though. Just like incandescent lights and fluorescent lights are a different shade of white, LEDs are yet another shade of white. It would be nice if the color could be changed, but even the way they are would be good for hallway lights and bathroom lights.Is it possible to increase CRI of LED lights/strips by using different ones together?OSRAM published an exhaustive document explaining the limitations of CRI and the case with deep red. It also describes the mixing of white LEDs with amber LEDs to obtain a high-CRI (including R9) light with high emission efficiency.http:/ledlight.osram-os.com/wp-content/uploads/2012/02/OSRAM-OS_WEBINAR_HighCRI_06-26-12. pdf.Ohms law and LED driver efficiency? How can this possible be true?He's trying to sell you something that consumes > 30 W as a "30 W driver", whereas it actually can only supply less than 30 W. The ratio between power that goes in and goes out is called the efficiency. The difference in power in and out is simply converted to heat. You can upgrade your LED driver to a 2500W LED driver simply by putting it in parallel with a water heater of roughly 2470W, or any other resistor, for that matter. You can simply waste more energy.So, that's what we call a scam and that's why we only buy from reputable sources in jurisdictions where one can ultimately sue someone.As a personal note: Do not argue with someone who will be getting your money. Simply make "fulfill this or do not get the deal" statements. Make the requirements verifiable, as in "The driver has to deliver /$x/$ A at /$y/$ V with a ripple of less than /$/delta/$ V and without getting hotter than /$T/$ °C in continuous operation. These are my requirements, and I can only pay for equipment that fulfills these. ".Broken LED's on PS3 controller?As far as I remember, the LED unit is one piece, but you wo not really know what is broken unless you open your controller and look in there. You may be able to salvage the remaining LED's but I am not sure. Opening it and taking a look will be your best bet. If they are soldered to the board then, no; unless you can solder it yourself and do it that way. If it's a plug or wire or something like that, it should be simple. If it comes off, it should be able to go back on.Which tv is better for movie viewing experince LED OR PLASMA?LED is better by a long shot, here's why: - Superior picture quality, with a seamless refresh rate. - Cost Effective - Viewing 3D movies with an LED is so better - And of course, if your a gamer, you can enjoy that amazing virtual graphics that the PS4 is capable of creating.how much to fix an LED tv with a cracked screen?Just too bad . to replace the “ LED display display panel “ total cost is about 85 % of same screen size new LED TV. cracked screen = DISPLAY PANEL. cannot be repair-change parts . need to replace !! display panel sold as spare parts with out warranty. you take own risk after replace . get an new TV consider is much cheapest.Can an RGB LED reproduce the colours as we see on a PC monitor? [closed]Sounds like it -might- be working the way you need it to. What you are missing is a diffuser/combiner for the light coming from the LED. When you look directly at an RGB source that's not diffused you will see the individual colors. As for dark grey vs white, that's a matter of relative intensity (assuming everything's balanced).I've used ping-pong balls for diffusion- I am sure there are better solutions but that's what I had at the time. You could also try sanding the LED lens so it acts as a diffuser. If you let us know what you are trying to accomplish we might be able to come up with a more 'targeted' solution/suggestion for youIs LED lights really that wonderful?LED lighting uses approximately 10% of electricity than that of a standard light bulb. Energy efficient LED lighting creates less carbon emissions, which helps our environment as well as saving you money. :)Can I replace a Maximum Bulb Wattage (Watts) 25 halogen light bulb with 5w LED light bulb? Is it safe?When choosing lamps, as long as the actual wattage is below the rating of the fixture, you are safe. It does not matter that the fixture generates a lot of light with the watts it consumes. The equivalent wattage they talk about, like where they say this 3W LED has light output equivalent to a 15W halogen, does not matter when selecting lamps for a fixture. The 3W actual wattage determines how much heat it may generate, not the 15W equivalent light output. In fact it's likely that the LED is more efficient, with less of the electricity consumed turning into heat and more into light, but you can not count on that. Just go by the actual wattageWhy did my 9V battery die when hooked up to a simple LED light?Very undesirable theory or layout to skill unmarried LED with 9v cellular, 70% of cellular capacity develop into wasted into ineffective warmth. replace it with 2 AAA cells to make a 3v battery %.. placed one 30 ohm 1/2 watt resistor in sequence with LED shall gentle it up and extremely last 10 circumstances longer than 9V cellular.
LG 47" LED TV Won't Turn On?
Use your warranty it does sound like the geomagnetic problem. In future run it through a surge protector and in power cuts unplug before power returns as this is usually when damage occurs,1. Garbled text when using a 32in 1080p Sceptre LED TV as a computer monitorDownload CRU (Custom Resolution Utility) and change from "Default extension block" to "No extension block". Then, either reboot or run restart.exe/restart64.Note that you will lose audio with this method.I just picked up a similar Sceptre TV (E246BV-FHD) with the same issue.edit: I am using this method with an AMD video card and am noticing that my display settings are being reset on every reboot (monitor positions/orientations). I am looking into this now.If you are still using a nvidia card, look at the "Change resolution" section of the nvidia control panel. There should be "Ultra HD, HD, SD" resolutions as well as "PC" ones. If you can select 1920x1080 in the PC section, it should work without needing to use CRU. My PC section maxed out at 1680x1050 for some reason.You can try playing with the signal type, but it did not help for me. And those options are not present when in PC mode, so the colors are definitely off (not a big deal by itself, but it's noticeable in a multi-monitor setup). But that's for another day. At least everything is crystal clear now.edit2: I reset all the profiles, rebooted, set all the positions and orientations, then modified again with cru. It looks like there's some sort of switching happening on startup. All good now.2.

Plasma does not have 60/120/240/480/960/1920 hz, only cheaper technology like LCD does. You probably wont find a plasma smaller than50". Panasonic makes a 42" , but they are not in Walmart,Target or other 'junk tv 'places.8. Which LED TV should I choose for gaming: Samsung un32F5500AFXZA or the LG 32LN5310?Rule of Thumb: Buy what you can afford9. led tv power usage - 60 inch?The math is easy once you know your electrical power rate. In the U.S., 15 cents per kilowatt hour (kwh) is typical. You can find your rate on your monthly power bill. A 60 inch "LED" TV will draw something like 150 watts (see the link). At 150 watts per hour, it will take 6.67 hours to use 1000 watt-hours, or one kwh -- 15 cents. Divide that down and your cost is about two and a quarter cents per hour, $0.0225. So multiply that by 8 hours and your cost for the day is 18 cents. (You can adjust the math as necessary if your power rate is not 15 cents.) There's also a tiny cost when the set is "off." It's not really off, or else you could not turn it on with the remote. In the "off" (actually standby) state, the set draws one watt or less. Work the math on that and you have something like a dollar or two for the year if the set is in standby 16 hours per day. - - - - - Followup: I looked online at three LED sets 55 to 64 inches, and based on those specs, I would say the power consumption curve shown in the link is a bit high. 100 watts for a 60-inch LED set would be more like it, so that would trim the above daily costs even more.

My LED TV has fingerprints, how do I clean it?Using a dry cotton towel should remove the finger prints. But do follow the directions that came with the television.
