I'm not sure what games you are playing, but every game I play looks decidedly better at 1440p over 1080p
you are missing the point entirely... at 2-3 feet on a 27" 1080p screen I can see individual pixels because the PPI is too low... at 1440p that goes away, but I want a bigger screen than 27"
I currently have 7680x1440 but i don't really like the letter box effect, I would much prefer to have 1 large screen at a higher resolution
I already know that you game on a big TV from like 8-10 feet away, so it is totally not the same situation... go sit 2-3 feet away from your TV and then tell me it's a good way to play and that you would get no benefit from a PPI increase
no you dont see anything on 1080p at 8ft on a Panny plasma, the image is sharp and perfect, but i did on my last HD TV, BECAUSE it's not just down to 1080p, it's the quality of the screen panel that's critical... i.e the Panny has additional Pixel smoothing, sharpness functions/ professional calibration settings etc.
a monitor is no use to me at all because it's way too small at 8ft away....i've never gamed via a monitor, so your arguement does not apply to me.
so for me, a 4k OLED is useless for gaming, because as said, the games modelling isn't going to look any better on 4k, because as said it doesn't have enough detailing in the 1st place.
it looks good on a minitor, yea because it's a tiny screen, so a coffee mug is much smaller and the faults are bound to be hidden, but you wait till you see that on a 55'' screen...it'll look awfall.
conclusion:- raising the res wont help for gaming on a big screen, until you raise the quality of the modelling as well, all an OLED will do is to improve colour/ contrast/ motion handling/3D/ refresh rate and finally sharpness.
e.g DOOM 3 will still look bad on a 55'' 4k OLED, just like it does on my 55'' Panny right now.
model detailing, it's critical on a large screen, you'd know exactly what i mean if you saw my tv..... i get truly awesome lighting/ water effects/ DX 11, in fact, it looks as good as BLU-RAY, it's the items up close that look so wrong, but it is getting better.
