Custom Resolution Utility (CRU)

[XAGMNINETY]

Hello again,

I was here sometime last year when I successfully added multiple native refresh rates to my laptop's 144 Hz (non-GSYNC) screen. Great for getting locked frame rates at native refresh in games that can't hit 144, which outside of esports titles is essentially all of them.

Out of the box, the laptop screen natively supports 60 and 144 Hz. However, an upgrade to Windows 11 has completely borked the rest of my working custom refresh rates for this screen, and I'm scrambling a bit to try and get them working again.

I had (and still have, to some extent) the following refresh rates, all at 1920x1080:

75 Hz
90 Hz
100 Hz
120 Hz

None of these custom refresh rates work anymore after the upgrade. 75 Hz in its current state gets me thin horizontal bars and no display, forcing me to reboot in low-resolution mode to get back out. 120 Hz and 90 Hz modes both have lines at the bottom of the screen near the taskbar, and 100 Hz essentially becomes "50 Hz" mode, where the BlurBusters stutter test shows the first two lines, reading at 100 and 50 Hz, as the exact same moving picture.

I was wondering if I could get some help reconfiguring these refresh rates properly, as they were a staple of my mobile gaming experience before upgrading. I cannot stress enough - all of these refresh rates worked just fine before the update, frequently tested with different games with RivaTuner up, all reading out properly with no issues or screen oddities. I didn't change a single figure when upgrading in CRU itself, although that's not the case anymore, as I've tried a few things with the values to no avail. As a note, I also use CRU on my desktop hooked up to my OLED, and the CRU-added 100 Hz refresh rate still works just fine in that use case after a Windows 11 upgrade.

Thanks in advance.

An update - my Intel automated assistant assumed that I was on the latest Intel Graphics driver (the laptop uses both Nvidia dedicated graphics and Intel UHD 630), when in fact I was not. After downloading the latest driver, the horizontal lines and major monitor failures are now gone. Leaving this for reference for others. I was, and still am, on the latest Nvidia Graphics Driver.

The 120 and 90 Hz CRU added detailed resolutions now work properly.

The "half refresh rate" issue still exists on both the 100 and 75 Hz modes - as in, these refresh rates log at 100 and 75 Hz, but present themselves at half their refresh rate. I could still use assistance on getting these to work properly.

Thanks.
