Just found Acer’s 21.5" monitor for roughly $140 with 4k… it looks amazing but probably is cheap. i’ve personally tried 1080p at 10" and basically dealing with squished resolutions brings out the 3d effect and or realistic effect… so, yeah it looks like the ultimate capturecard monitor too… no hdr… UM.HB6AA.B03…
all that being said, i still would rather a render resolution that is up to the 200% instead of buying a 4k monitor…
