I agree.
And you would need an even bigger one for UHD.
The point is that people, who actually sit in accordance with correct viewing distance/resolution measurements, are in the extreme minority.
Let's take a 46" FHD for example. Do you honestly know of a lot people whose lounges/TV rooms are set up so that they're 1.75m away?
I certainly don't.
Of course we have to generalise here. Some people live in flats, some people live in houses. Some people watch TV in their bedrooms, and use their TV as a PC monitor, so would inherently sit closer, etc. Some people have better eyesight, etc.
I don't think that's a thing anymore. Maybe back in the CRT days, but with an LCD you'd have to be sitting with your nose touching the screen.
Can we agree to disagree, and go back to posting Hardware Bargains?
