Custom Resolution Utility (CRU)

[EeK]

@ToastyX, I'm having a weird issue after using CRU, while on the latest Nvidia driver (441.08).

Prior to installing 441.08, I'd been using the 440.52 beta driver, as that was the only one with support for G-Sync on the LG C9 series of TVs.

Everything ran smoothly, and I was able to add a custom resolution of 3840x2160 with a refresh rate of 66Hz to my display, via CRU, selecting LCD standard as the timing. If I were to use NVCP, the only color format and depth available would be RGB and 8bpc, for some reason. With CRU, I could select YCbCr444/8bpc and YCbCr422/10 or 12bpc - the latter being my preferred choice.

As always, I used DDU before installing the new driver. The installation was successful, and I then used to CRU to add the same detailed resolution as before. However, after running restart64.exe to restart the graphic driver, my whole system rebooted and got caught in an infinite reboot loop.

I was only able to do something when Windows automatically prompted to boot into safe mode, after a few failed login attempts. I the uninstalled the driver, again using DDU, downloaded it once more and clean installed it a second time. Also for the second time, running CRU would result in the same issue.

This, time, I simply ran reset-all.exe while on safe mode and that stopped the infinite rebooting. However, I'm still unable to add a custom resolution at the desired refresh rate.

Do you have any idea what's causing this? It's the first time ever experiencing this issue, after literally years of using CRU. Aside from the display driver, nothing changed between 440.52 and 441.08. I'm still running the same (updated) version of Windows, the same TV (on the same firmware), etc.
