Ok, so I am having a heck of a time trying to set a refresh rate to my liking on my gaming setup. What I am trying to get to happen just probably isn't possible, and most likely a lack of understanding on my part, but I would appreciate any help.
First off, I game on a 4k LED tv, at a resolution of 2560x1440 at 60hz. Now to get that resolution and refresh together, I had to create a custom resolution via Nvidia Control panel. By default, there is a resolution listed exactly as "4k x 2k, 2560 x 1440", but it only goes up to 30hz. My custom resolution allowed me to attach 60hz to it, which is why I went that route. Here is what is confusing me though...if I choose the already available 4k x 2k option, my monitor reads it receiving a signal of 2160p, proper 4k. However, when I use my custom resolution to get 60hz, my monitor only reads it is receiving a signal of 1080p. Now it is clearly not a true 1080p, as there is definitely a difference between the native 1080p setting and my custom 1440p setting. However, I swear when I compare the 4k 1440p and my custom 1440p, the 4k setting looks slightly cleaner, though not significantly.
What I really want is "4k x 2k, 2560 x 1440", and 60hz. I have also tried just doing a pixel overclock to 60hz from the 30hz under 4k, and it only allows me to go to 56hz, which won't even display anyway. One other tidbit of info, if I set my resolution to a true full 4k of 3840 x 2160, I can set 60hz, but at that resolution and high-ultra gaming settings my setup can only push out 30fps, which is not preferable to me. Any idea why I can get 60hz at full 4k, but not at 2560 x 1440 without creating a custom resolution, and losing the 4k signal my display would otherwise receive?
