Sure it will help. Before 1440+ monitors, all we had was AA and AS, such as AA, 2XAA, 4XAA , SSAA, MSAA, and anisotropic filtering, and so on.That's not going to help because the issue is largely that 1080p simply has less pixels than 1440p or 4K to resolve fine detail.
I realize there isn't any exception for more pixels, however. Also, the desktop will have more space with 1440, and I do like that. Putting 1080 in a 32" monitor is kinda a waste of screen realesate, really.
I was just wondering how much better the 1440 will look vs 1080 on a 32" monitor when all of the texture filters and AA are turned on on the 1080?
