There is no amount of spin that will make 32" 1080p screen remotely equivalent to a 65" 4k screen. Not even in terms of jaggies. You have two people here with essentially that same setup (myself and Overclockin), our eyes do not deceive us. Jaggies are more apparent on the smaller screen with 1080p than it is on the bigger 4k screen, regardless of pixel density. You can't sweep resolution clarity under the rug like that.
Agreed. I needed 4x AA at 1080P to get my preferred visual quality. I can actually game at 4k with no AA, but I do prefer at least 2xAA to eliminate shimmering. The jaggies are acceptable though, where 1080P is intolerable to me.
