REAL 4K vs 2560x1440 downsampling to 4K

[Death Prodigy]

Is 2560x1440 downsampled to 4K as good and clear as TRUE 4K at 3840x2160 with 4x MSAA or even 2x?

I think that's upsampling...

No. You don't get extra data; you're just extrapolating.

I think you mean "4K downsampled to 2560x1440"

And NO, it can't be identical if you are comparing two different monitors with a different amount of pixels.

4K at the same settings gets only HALF the frame rate usually for gaming as 1440p so there are currently very few scenarios that make sense to game at 4K.

It would generally make more sense to run a game on a 4K monitor at 1440p due to the very small performance difference and enable some anti-aliasing, or better yet (for now) just get a good 1440p monitor.

If you're in the market for an expensive gaming monitor and have an NVidia GTX600/700, then one of the new G-Sync, 27", 2560x1440 monitors might be ideal. You can Google Linus from Techtips (video), or "one week with G-Sync" (article) for more feedback.

Photonboy: I have been on NVidias nuts since I heard about G-sync back in October and would get angry at the lack of up updates/expensive options that I ended up getting a 780ti OC to distract me... I can't wait for all the screens we've been hearing about... and even better the ones we haven't heard about!

OP: Most 4k screens are 30hz or 60hz! Are you a gamer? Do you really want a slower screen/slower FPS? 2k 120hz (ROG SWIFT) is where it's at.

Yeah I'm a gamer but frankly 60Hz is enough for me and unnoticeable when you have insane image quality with 4K
