Are LED TVs glare-proof? Is it worth the cash difference from LCD?




Icebox -0:


Oh yeah, and if the TV I have now is a 25 inch CRT, is 32 or 37 inches the ideal upgrade?
Also, video games will be the primary usage of this tv.
40 inches would be WAY too big for this room, but thanks!



Answer
my roomate bought a samsung 50 something inch led TV (was even 3d), however since the windows were opposite the tv, when it was bright we did get a decent bit of glare.

Sometimes u can get more vibrant colors on LEDS. Its best to go to store to see which picture quality you like. Just make sure its 1080p. You can get a 40" 1080p tv for 500, brand new if you look hard. Slickdeals dot net is a good place to start

Emerson LCD or Samsung LED tv?




Ryan


I am going to buy a 32" HDTV. There is an Emerson 32" LCD for $150, or a Samsung 32" LED for $250. They both seem to look the same but the Samsung being LED seems way more expensive... So I just want to know what the better deal is? Thanks.


Answer
Any TV that is LED is going to be better quality. Reason being is because an LED TV will give you a more detailed picture, and the colors will hold true from off angle positions in the room. A LCD screen will look good from straight on, however when you start looking at it from off angles, the glare from the light in the room will begin to hit the screen.

Tv 120hz vs 240hz which would be better?




Jesus


Ok so I'm looking for a new tv and I really don't know about the whole hz and fps.
My friend recompense me to get one with 240Hz. Will that picture look good?
He has one that is 240hz and when I saw it it looked like I was actually there in the tv show. Idk if the Hz caused that but does it make it look like realistic?
-And do you think the Vizio tvs are good?



Answer
- Top brands: Panasonic (Plasma) and Samsung (LED). (Plasma > LED > LCD). (LCD is going to be discontinued. A LCD tv uses cold cathode fluorescent lamps/CCFL backlights. A LED tv is a LCD tv, but with white or red, green, blue LEDs on the edge of the screen or a full array on the back of the screen).
= Plasma has best picture and audio quality (best response times, best viewing angle, best color quality, less/no motion blur for crisp/clear images because how it's refresh rate works). Newer Plasmas have improved their burn issues by using pixel shifting/scrolling. LCD/LED is best for bright rooms and have most light coming off the screen (Plasmas are not great for bright rooms because of screen glare and faded whites, but do great for dim or dark rooms). Newer Plasmas use less energy consumption and they are cheap to buy. LED are more popular because the manufacturers want to sell you their LED expensive tvs rather than their cheap Plasmas.

- I recommend 1920x1080p for movies, computer monitor/display, some tv shows, and some game console games and I recommend 1280x720p for some tv shows and some game console games. I recommend 40+ inches for movies and/or tv shows and 20-30 inches for computer monitor and 30-40+ inches for game console games.
- FPS (frames per second): Every video consists of a number of frames per second, think of a video as a fast moving flip book. NTSC countries use 60i or 30i FPS (newer stations use 30p or 60p FPS) for tv shows. PAL/SECAM countries use 50i or 25i FPS (newer stations use 25p or 50p FPS) for tv shows. Movies use 24p/25p/29p/30p FPS (first movie to use 48p was LOTR: The Hobbit). Games use anywhere to 2 to 120 FPS (older games use lower FPS while newer games use higher FPS, usually they are up to 60 FPS today).
- TV refresh rate (measured in hz): Example, A tv with a refresh rate of 120 hz means it refreshes/flashes the entire screen 120 times a second.

- How do LED or LCD tv refresh rates work with the FPS of a video? (I recommend real/true 240hz refresh rate, some tv advertising may fool you by listing the fake interpolation or fake backlight scanning/dimming refresh rates).
- http://en.wikipedia.org/wiki/Motion_interpolation (Names of the new technologies for newer tv's at the link): Motion Interpolation or Motion Compensated Frame Interpolation (MCFI), is a form of video processing in which new fake frames are generated between existing ones to up the FPS of a video to reduce motion blur and/or for judder removal/judder adjustment. MCFI video processing may cause gamer input lag and/or artifacts such as the soap opera effect (may ruin the look of a video).
- Many tv's allow viewers to turn motion interpolation (MCFI) off. The tv repeats the frames a certain number of times to match the tv's refresh rate. Example; To display 24 frames per second on a tv with a 120 hz refresh rate, each frame is repeated 5 times every 24th of a second.
- But what happens if the FPS of a video does not match the refresh rate of the tv? Then you get a pulldown, a pulldown is what causes a jittery screen (aka judder) because the tv repeats the odd frames a different amount of times the tv repeats the even frames. Example; A 3:2 pulldown is post popular because it is needed to match a 24 fps video with a 60hz refresh rate tv, odd frames are repeated 3 times (12x3=36) and even frames are repated 2 times (12x2=24) and 36+24=60 FPS for a 60hz refresh rate tv.

How does Plasma tv refresh rates work with the FPS of a video?
- It will take each pixel in a frame and and repeat it a number of times based on the number of sub-field drives (SFD) the tv has with it's refresh rate. Example 1; (NTSC countries) 600hz sub-field drive/motion tv means 60hz FPS x 10 sub-fields per frame = 600hz refresh rate. Example 2; (PAL/SECAM countries) 600hz sub-field drive/motion tv means 50hz FPS x 12 sub-fields per frame = 600hz refresh rate.
- What is focused-field drive (FFD) on Neo-Plasmas? (Light switching speed = better colors and less motion blur) 2500hz focused field drive means sub-fields are virtually packed into 1/2500th of a second as a sharp impluse, creating crisp motion images even in very very fast movining images (FFD is defined as a inverse of light emission period t. 1/t = 1/0.4ms = 2,500 FFD). Regular sub-feild drives like 50 FPS x 12 sub-fields = 600 hz, light emission spreads as wide as 1 field time (1/60th sec) maximum which results in blurry images for very very fast moving images.
- Refresh rates on Plasmas work similar to LED/LCD tv's. These settings are usually automatic, but you can change them in the advanced picture settings, Example 1; 2D 24p FPS mode and choose refresh rates of 48hz/96hz or 30hz/60hz with pulldown (might use interpolation frames for pulldowns), Example 2; 3D mode and choose refresh rates of 96hz for 24 FPS or 100hz for 50 FPS or 120hz for 60 or 24 fps.ect Of course it has gamer mode or many other adjustments.

Some of the information may be outdated/wrong, but still some useful information.

- http://reviews.cnet.com/3dtv-buying-guide/
- http://reviews.cnet.com/best-high-definition-tvs/ (has models and reviews + more).

- Off brands use crappy/cheap and breakble electronics. For gamers I recommend the tv has at least duo/quad processores and gamer mode (gamer mode turns off stuff that requires processing/cpu power like upscaling/downscalling resolutions and/or interpolation/reapting frames for refresh rates.ect). TV's do have a input lag specification.

Is it worth to purchase showpiece led tv in showroom?

led tv glare
 on 55 inch TV-Protector Anti-Glare TV Screen Protector for LCD LED ...
led tv glare image



Raghu


I went to tv showroom, I selected
Samsung led tv, but the thing is he
don't have another box piece!
(wrapped new tv).. He said he only
has demo piece, which kept it open
for viewing customer. He said its new
piece only., is it ok to purchase that
tv?,?



Answer
The advantage is that you know it works and what it looks like - I would check carefully up close to be sure there were no dead pixels or any lines that should not be there, but if it looks good, and IF you get a percentage off of the price, and also make sure you'll still get the full warranty (usually a year on parts and workmanship), I'd do it.
You will probably want to recalibrate it (adjust picture settings) when you get it home, as showroom TVs usually have the brightness, contrast and backlighting cranked up to full to overcome showroom bight lighting conditions and screen glare, to make it look as bright a picture as possible. Often taking all 3 controls to 50 - 60% is a good idea (use your eyes to judge, or get a calibration DVD - here's a free file you can download/burn to do this if you like; read the instructions carefully):

Good luck!

What is the best reasonably priced LCD TV?

led tv glare
 on Recently, LCD TVs (also dubbed LED TVs) have made great technological ...
led tv glare image
Q. A TV under $2000 and not a power hog? Exclude sharp, or DLP type tvs. What is the best way to test or determine whether for instance like the differences between the tvs for different refresh rates say 60hz, 120hz or 240hz etc? What are your experiences with your tv that you have just purchased did you get a good deal and where did you find the deal?


Answer
Look into a Panasonic plasma. You can find up to a 50" for under $2000. LCD's are not worth the money. Pretty much any plasma you'll find out on the market now will out-perform any LCD you put it up against, even an LED. And dont be scared off by what some people may say about plasma's. Most of their information is out-dated. Burn-in is no longer an issue. You'd have to be TRYING to burn-in an image for it to even be an issue, even then its only temporary. Any burn-in will correct itself after normal viewing on the TV. Image retention on any LCD is permanent. Although its extremely difficult on either type of set. LCD's have poor response times which lead to motion-blur. Most newer plasma's have .001ms response times(almost instantaneous) where the best LCD response time I've ever seen is 2.4ms, with most LCD's having between 4-6ms response times. LCD's have poor viewing angles(when you move off center you lose picture quality and color) when comparing it to any plasma. And contrast and color accuracy are far better on any plasma. "Well what about glare?" loads of people would say. The only LCD's which actually combat glare have extremely matte finish screens. The color on those sets are horrible. It's as though youre looking at the picture through a foggy window, the colors extremely dull and faded. LCD's with the best color have a gloss on their screen which give equal amounts, if not more, glare than a plasma. As for power consumption, plasmas do use more power, but we're talking about $1 more than an equal size LCD. You can use the money you saved getting a plasma towards that $12 a year extra you'd be using. In the end, look up any LCD v Plasma rating that actually gives you a winner(not just state the differences) and you'll find plasma's blow LCD's out of the water. Plasma= more TV for less money.

Do all LCDs have backlight bleed, in the corners and such?




DustInDeni


I just exchanged a 40 inch LCD or an same-sized LED-LCD TV the other day, hoping I would no longer have the annoying backlight bleed in the corners. The new TV just has the bottom corners lit up instead of the top corners. Not as bright either, but still a little annoying. Keep in my mind that I'm budget-constrained and spending a thousand bucks or more on a higher quality TV, maybe not purchased at Walmart, is not in the question right now!

I'm beginning to think that if I want an LCD or LED TV, I'm going to have to deal with backlight bleed of some sort! I've heard they all have it to some extent.

There is a 43" plasma in my price range, but it only goes up to 720p (as opposed to 1080p). I've also heard that plasma have bad glares due to glass screens. At this point, I don't think the 720p thing would bother me, because I can't tell a damn bit of difference between a DVD and a Blu-ray in terms of quality anyway! Of course I've never watched the same movie on DVD and then Blu-ray, so I can't say for sure, but the only significant difference I notice is the cost! Is this another problem with lower budget TVs?

I'm really starting to miss CRT (old school) TVs. Bigger picture size and HD doesn't mean squat to me if I'm forever having to deal with backlight bleed or terrible plasma glare. Any advice or help would be appreciated. Also, if anyone knows of any really good TV models at Walmart (or the like) for like $500 or less, and can let me know what they are, that'd be great! Thanks!



Answer
all LED/LCD TVs will have a small amount of bleeding, the least is called a full-backlight, where there are LEDs positoned all the way across the back of the display, but this is also the most expensive

plasmas don't have this issue due to them not having any backlight.
