I guess if they are $500 or less it would work. Otherwise you are spending a lot for lower pixel density, and I'd probably just use some commodity $120 1080p IP

I guess if they are $500 or less it would work. Otherwise you are spending a lot for lower pixel density, and I'd probably just use some commodity $120 1080p IPS panels until 4k ones came into a reasonable price range with IPS 60hz 2160p panels between 24 - 28".
