Talk:Downsampling – A full guide to achieve 3840x2160 resolution – NVIDIA only/@comment-67.4.63.184-20160401105634

This guide served it's purpose but it's no where near Real 4K. I went and did my own custom resolution. I used 3840x2160 of course but i edited the total pixels to be 3840x2160 also as then you will get an actual 4K image. Now it won't be exactly 4K as a real 4K Display has better color support but this custom resolution will get you to 4K it just won't be 100 percent. But it's way better than what this guy has.

For Refresh rate it depends. I'm using a HDMI 1.4 so i'm limited to 35HZ on the refresh rate with the MHZ going to 305mhz. Anything over that and no image appears.
