First i'll like to say, thanks so much for the tool! .

The only problem i have is that the tool does not seem to recognize anything past 4095 Horizontal pixels.

I downsampled my 21:9 2560x1080p Dell Monitor to 5120x2160 30Hz for benchmarking purposes, but applications do not recognize the refresh rate, so i was trying to set it through CRU as usual, but it turns red whenever i input 5120

Could you increase the limit on the tool? Or is it something that can't be done. Either ways, thanks a lot

That's an EDID limitation. There's no way to define 5120x2160 with an EDID override.

Either the TV is skipping frames or the game is limited to 60 fps.

Use this test with a camera to check if the TV is skipping frames: http://www.testufo.com/#test=frameskipping

Yes, but it requires their API, which isn't publicly available.

This is unusual. Nobody else has ever reported this happening. This could be caused by an antivirus program doing something weird, or it could be a CRU bug. This would be hard to debug without seeing it happen myself.

Higher resolutions will only work if the monitor can handle them.

The panel can only display the native resolution. Other resolutions would have to be scaled, and it's up to the monitor whether or not it can scale down higher resolutions.

It's possible to do scaling on the GPU, but not with CRU. CRU only deals with monitor resolutions. Since you have an NVIDIA GPU, you can use this process: http://www.neogaf.com/forum/showthread.php?t=509076
