Custom Resolution Utility (CRU)

[DustinEarnhardt]

Toasty,

First off, thank you for all the time it took to develop this utility and for the continued support for several years helping others solve problems. Reading through these forums, it is incredible to see the amount of effort you put in to help others. It is my hope that you can help me as well.

Background:
Graphics Card: XFX Radeon 6870
Monitor: Dell P2715Q
Display connection: MiniDP
OS: Windows 10
Driver: 15.201.1151.1008

I recently purchased the Dell monitor with hopes of running 4k at 60hz. I know this is likely pushing it for the capabilities of my video card, but I have heard that some people can at least get it to run at 45Hz with CRU and the pixel clock patcher ( http://www.hardwareheaven.com/community/...ys.226759/ ). I've already run the pixel clock patcher (thank you again for that utility) and it worked effortlessly. Where I'm struggling is to get custom resolutions to appear as an option in Windows 10. I have read through many pages of this post (though, admittedly, not all 259 of them) and I think my problem is largely just due to not understanding what I'm doing with CRU. Below is a screen shot from CRU. After I click 'OK' and run the restart utility (I've used both 'restart.exe' and 'restart64.exe') my display driver successfully restarts but I do not seem to be able to get anything other than a 3840x2160 @ 30Hz to be able to appear.

I've tried to add 3840x2160 @ 60Hz to the standard resolutions box and I get the red text telling me that it's not supported.

I feel rather sure this is an operator error, but hopefully you'll be able to point out what I'm doing wrong.

Thank you!
Dustin
