the VGA cable supported up to what we now call 4k resolutions, albeit not at the same color and refresh. Hell, I remember having 1600x1200 monitors 20+ years ago.. a bit less than the most common display resolutions today (1440p). 

And I am not sure it will keep changing. 4k is already overkill for most situations in homes. We're waaay into diminishing returns territory when it comes to pixel count. Now other features like max refresh, VRR, and improved HDRs.. that's another story.

I don't think we'll go above 8k.

at that point every game will be fine without anti aliasing.
