1440p Is anti-aliasing needed at higher resolutions?

[Jake.E20]

I have been looking into getting a better monitor. I would like it to be a noticeable upgrade from my current 1080p panel. I have looked into the LG Widescreen 5ms 2560 x 1080 monitors https://www.amazon.co.uk/gp/product/B01BV1XB2K?pf_rd_p=9daa0afc-fa5f-4673-9ff4-e926d27e7d1b&pf_rd_r=1JBSV52GAMAZETM3KJW1&th=1 and also the AOC 1440p 1MS monitior 27 INCH. https://www.amazon.co.uk/AOC-Response-Monitor-Display-Q2778VQE/dp/B00U2ZZX5A/ref=sr_1_1?ie=UTF8&qid=1509991952&sr=8-1&keywords=aoc+1440p

Now my GPU can run my games at 1440p at settings I am comfortable with (Using DSR) but I noticed that turning off MSAA and FXAA (More MSAA) yeilded more FPS in my games. So I wonder is AA still warranted with these higher resolution monitors or is the jagged edges still a noticeable Eye Soar? Any Options would be great as would like to think what other people think.

It is mostly personal preference. I personally dont notice any jagged edges and i play with AA off. (I play on 1080p 144hz)

They more or less disappear at 4k, it'll be pretty good at 1440p too I believe.

If the edges are jagged depends on how much of your field of view a single pixel accounts for.

The easiest way to compare that is using ppi and viewing distances. If your current 1080p monitor is 20 inches diametere

it would have about the same ppi as the 1440p 27 inch monitor, so from the same viewing distance the aliasing would be just as bad

with the 27 inch monitor. if you double the ppi and keep the same viewing distance the same the aliasing is reduced like 4x SSAA,

if the PPI is increased by around 40% it is like 2x SSAA. Moving from a 1080p 27 inch display to a 27 inch 1440p display is

a bit less than 2x SSAA.

In general from normal viewing distances with decent eyesight youll still see some aliasing on those displays, but with fxaa

or msaa 4x the aliasing will be pretty much gone.

Ive found at 8k, that you need at least x16 msaa other wise the edges are super jaggy! (100% false)
