I never watch TV from the same plane that it's hung, so extreme viewing angles mean nothing to me. In fact, I prefer a narrow viewing angle as it's inefficient to send light to corners of the room nobody is sitting. I'd be happy with a 90 degree field of view.

Funny that plasma is what the industry quit. They had excellent dynamic range.
Hopefully OLED comes down in price and durability improves. One thing though, OLED consumes more electricity than LCD, but I'm not sure why. LCD wastes the light not needed to produce an image while OLED simply produces the light that is needed, and nothing more.

What about scopes in the future?
They will create a escuse for scope in Star Trek 23 century, like saying it was special devices to project 3D images or nearly holografic, and track eyes moviment to allow great interaction not possible with colletive large screens.

I got mad with people who refuse to admit the LCD/LED TVs are poor in dynamic range, specially when such people start to tell me it's just a matter of calibration of settings. But if they calibrate settings to reduce a lot clipíng and crushing, the image became lifeless. This do not happen this way on CRT.
Other people start to tell me it's because a given video was not in HDR, but CRT can run videos not made in HDR and have nice glosy look withpout clipping or crushing.
It's insane how they refuse to admit LCD/LED screen are terrible for dynamic range. What they refuse to admit it???
I'm not sure about OLED dynamic range, but I don't think it's great. The videos I saw wasn't good to judge, since I think it was in HDR, and HDR it's a trick to try to make a screen look like it had more dynamic range than in reality.

Some LCD/LED TVs have a LED backlight field that cut Of Leds light where the image it's suposed to be very dark. This save some energy and increase contrast ration, but each the LED are much larger than a pixels, so tris trick also have limitations.
LCD/LED TVs without such backlight trick can't save so much energy.
Hopefully OLED comes down in price and durability improves. One thing though, OLED consumes more electricity than LCD, but I'm not sure why. LCD wastes the light not needed to produce an image while OLED simply produces the light that is needed, and nothing more.

The repair (bake in the oven at 350 F) I did of the digital processing board on my plasma TV finally failed, as was expected. Rather than subject the entire board to the oven again, I decided to try a heat gun repair. First attempt on a low setting for 1 minute did not fix it. I switched to high setting and in about 15 seconds caused 2 caps to explode off the board.
Now no video displays regardless of digital or analog input. I could replace the 2 blown caps which would be cheap and it might work, or it might not. Even if everything works, the repair would not hold up for more than a couple months. A replacement board if one can even be found would be about $150. I'm not sure a 60" plasma is even worth $150 these days. I'd hate to toss the TV considering plasma isn't made anymore, and it has a beautiful picture.
In either case, an LCD TV is likely in the cards during Black Friday. My chance to go 75-85". I've been prepping my wife for that reality by constantly mentioning it.

Eventually you'll move on to VR/AR headsets.
But you are going to trigger Al d'Arc.
All Darc — Maybe this will help?

I've already got Google Daydream, which is a cheap setup that uses your phone. It works quite well already. Combine with earbuds and movies are fun to watch that way.

When could I watch TV again???
In 4, 8, 12, 20 years?????
When TV will be free from anoying distortions, and when TV signal will be free from artifacts and image detail deterioration (specialy in motions)???
Fix a TV in the oven???
Crazy...
A micro electronic technician fixed two PC motherboards for me. He changed the capacitors that was damaged and the ones that was near to fail.
But if you prefer to change a Ferrari with damage and replace it with a new BW...

I bet it will have more artifacts, since people do not see 4K resolution unless very close to screen, and nobody sits close enough cause the LED screens sucks at close range.
If we slice a segment with 100 per 100 pixels, from a HD broadcast and comapre with a 100 per 100 pixels from a 4K, I bet the 4K will have more, I mean more per a given area (100x100) of pixels, bit they will look smaller since the 4K will be more compacted.
Watching some minutes of a soccer game other day, in a store, in a LED TV not so horrible for contrast. ANy very tiny very slow, ultra slow camera movimenta made the deatails vanish away. I poresume it's not just the compression and motion blur of LED screens, but the HD cameras, the HD CCD (sensor) have some limitations and need bo be more exposed than the sensors in SD video cameras of 90's.
It's just anoying to look at HD videos, broadcast etc...
