With 480p games and 320p games I get pixel perfect fullscreen. I'm mainly interested in DOS retro gaming. They had more wacky resolution because of the different TV standards and the need for overscan on CRT TVs.īut anyway, I'm on a 27" 1440p G-Sync display myself, and retro games do upscale much nicer than on my previous 1080p display. However, with that being said, console games usually aren't 480p, AFAIK. In DOSBox, when I upscale to fullscreen, 640x480 games will display perfectly, because 480*3 = 1440.

However, when it comes to pixel-perfect scaling, 1440p has an advantage over 4K, because it perfectly matches a multiple of 480. 24" 1440p has very high pixel res, and is quite "4K-like" and has the same pixel res as 36" 4K. 27" 1440p is quite a bit higher pixel density, but not quite "4K-like". A 34" 1440p display has the same pixel density as a 24" 1080p one.
