Which one is more harmful to eyes crt, tft, led, amoled, or lcd – quora gas x strips after gastric sleeve

* Sony is clearly best, especially with their excellent 65 inch budget TV’s and Samsung is a very fine alternative… Then have Panasonic more expensive alternatives… And there are also some silly expensive "design" brands, which not make finer screens… Mainly because excellent electronics, which create a perfect picture without any irritating errors and give fine upscaling, are very complicated to produce and rather expensive to buy… And many makers like LG don’t want to pay for the finer electronics, so they only have perfect picture quality in some very expensive models… But Sony and Samsung have already that technology "in house" and that is also why the amazing low cost OLED from LG have picture problems and bad upscaling, according to many user reviews… But Sony have some OLED models with WhiteOLED panels from LG and Sony electronics inside, which give you the finest quality, but they are naturally more expensive!

* Then is the LED in names, normally the type / method of backlight LCD panels / screens have… There has only been a few micro TV’s and game screens with LED pixels… Plus prototypes with Sony’s amazing "Crystal LED technology" that was more expensive to make than OLED so they didn’t release them!

* And then have many famous original makers (as Philips) simply stop producing TV’s and sold the brand name to factories in China… The Chinese company Hisense produce for example low quality sets as Sharp (who originally made the finest big screens in Japan) and Toshiba for America… And the Turkish company Vestel make clearly worse quality TV’s for Europa with over 30 old brand names as Sharp (some models) Hitachi, Toshiba, JVC, Sanyo and even some budget Panasonic!

* Look then for the right size, so you can view the finest details… A great TV should naturally be just like a clear window to another place and you need a 65 to 75 inch to see the finest Full HD details from 260 to 300cm distance, plus perfect eyes… See more about that below!

* Some shops try to fool you that you need 100hz or more… The truth is that some fine modern 50hz sets, handle movements very smooth and sharp… But not all 50hz sets, of course… And some older 100hz sets are actually worse than a fine 50hz set… A few shops show even special made videos to demonstrate the "huge" difference and sets with 50hz look then dramatically worse, sometimes even horrible… Even if exactly the same 50hz TV show movement just as nice (smooth and sharp) as other 100hz TVs, with a normal / ordinary signal, from a film or broadcast… Okay, it may still be a tiny difference, but it’s practically impossible to see!

* A really fine VA LCD screen must be able to show almost total black (sometimes after some adjustments) fine details even in dark shadows, details in white skirts and very bright white… An IPS LCD screen show better colours from the sides BUT normally just dark gray "black" instead, except some Sony that show very deep black… And WhiteOLED combine the best, total black and perfect colors even from the side, but they are very expensive or have both some picture errors and bad upscaling!

1) The first extra easy method, work only with a Full HD screen… And even if you have bad eyesight… Stand first so close, that you just can see the pixels and move then back max 10cm… Then can you enjoy the finest details in a Full HD picture… That is simply the optimal distance, because if you move back more, will you naturally see less and less of the finest details… But if the TV is 4K or UltraHD with higher resolution, must you use next method….

And most people sit too far away, to see any fine FullHD details… They have normally a 40 to max 55 inch TV about 3 meters from the sofa, when it should be max 160 to 220cm away and then is it naturally impossible to see the finest FullHD details… And then have 4K or UltraHD even finer details, which are even more impossible to see, if you not sit extremely close… Which mainly means, that you don’t have to invest in a UltraHD player and films… And most programs are shown in max Full HD anyhow…

But a fine 4K TV cost about the same as a fine Full HD and if your kids sit very close to the TV, can they naturally enjoy the extra up-scaled 4K details… And then can you also use a fine 40 inch 4K screen as a giant computer monitor (at the perfect 80cm distance) instead of four 20 inch screens *hehe*

2) If you use method one, with a FullHD screen and have perfect eye sight, will you see that the optimal distance is 10% shorter than twice the width of the screen… Or even more simply, the width of the screen x 1.8 and if you sit further away, will you see less and less fine FullHD details… And you get exactly the same effect with a 4K or UltraHD screen… But to see the even finer 4K or UltraHD details, must you naturally sit even closer and to see the finest UltraHD details (when you almost can see some pixels) must you simply sit little closer to the screen, than the screen is wide!

And an extra tip… A fine 55 inch TV cost often exactly the same as truly excellent "budget" 65 inch from Sony or Samsung… Because 55 inch are the most popular size, so they are normally overpriced and many think WRONGLY that 65 inch are too big, so they are often underpriced!
