I have a 4k TV and don’t get it either. Watched the odd video in 4k and the colors are maybe a bit crisper, but that’s about it. I’d have to compare movies side by side to actually spot the difference.
Not worth it IMHO.
Can’t tell for screens though, I don’t even know whether mine does 4k or not. Was part of the home-office package from my company. I’ll have to check that tomorrow, only returning from a business trip tonight.
The point of 4k is that you can have a TV twice as large as your 1080p TV before it without losing sharpness.
I can definitely tell the difference on my 77” OLED.
Mine is 65" and I really can’t, unless I switch between files rapidly. 720p to 1080p, definitely. But larger, hardly.
What is your viewing distance?
I’d say about 2.5 meters, maybe 3.
You should see a clear difference at that distance. You may want to get your eyes checked, your eyes get worse as you get older and it can really creep up on you without noticing.
I just did during my annual checkup 2 weeks ago shortly after turning 40, still got 20/20 vision. No idea then…
Strange. I used to have a 65” OLED, I sit farther away than you (about 3.5 meters) and could easily spot the difference even though I’m near sighted and at that time my prescription needed updating. Now, with new glasses and a 77” screen the difference is like night and day.
Maybe my TV is due for an upgrade then. Or the source movies I tried were 4k in name only but just some upscaled older ones… I’ll do some more testing with more recent ones.
The benefit of the higher resolution shouldn’t be about the colors, but that with bigger screens the movie does not start to get blurry.
For desktop use on a desktop display, I don’t see the benefit either. Even less on a phone, that is totally unnecessary.
