is anti-aliasing useless when gaming at 1440p and 4K?

[saiftech]

i heard that if your gaming at 4k or 1440p then AA is pretty much useless is that true?

 

so that would mean i can game on GTA 5 with everything set on max other then MSAA right? cause im gonna game on 1440p?

No. If you're close enough to the screen it's not useless, but it becomes less important. If you can still see individual pixels, then AA is still important.

2x for 1440p

 

I don't use any AA at 4K (28")

Depends on your monitor size.
And most of the time it is not useless, just barley noticeable and not necessary

At 4K it certainly is. Even if you say "it depends on how far you are from the screen and how large it is", if the screen is large enough and you are close enough to it to see the difference between AA and no-AA you're going to have a pretty hard time keeping track of the entire screen in a game

at higher pixel density, anti aliasing becomes a bit unnecessary. 4k with a 36 inch panel and 4k with a 28 inch panel is very different. 

higher ppi(pixel per inch) would require less, or no AA.

I wouldnt use AA if I had 24" 1440p monitor but I would use AA if I had 27" monitor.

I wouldnt use AA if I had 30" 4k but I would use AA if I had 40" 4k.

4k on a 40" TV, yes its needed up close, sitting back on the sofa? No and the extra frames help

4K doesn't need any. But 1440p needs about 2x-4x AA for you to not notice it at all.

I found a bit of anti aliasing still welcome on 1440p, somethings still look a bit jaggy, but it's nowhere near as bad as 1080p. Usually 2x, and 4x on some occasions.
