Custom Resolution Utility (CRU)

[mergen3107]

Hi!

Thank you very much for the program! Can you please help me with my issue?

I can't get down from 144 Hz to 60 Hz on my laptop, but only while in Hybrid graphics mode.

My laptop is Lenovo Legion 5 (2020), with AMD Ryzen 7 4800H CPU (which has an integrated graphics), Nvidia GTX 1660 Ti Mobile GPU, and 144 Hz screen which only allows to use 144 Hz stock. OS is Windows 10.

When I am in Hybrid graphics mode, I used CRU to create a new resolution with 60 Hz. Other parameters I just copied from the existing 144 Hz preset. Then I can actually see 60 Hz option in the Windows 10's Display Settings, the screen blinks as if it tries to adjust to new refresh rate, but in fact nothing changes. UFO test still shows 144 Hz.

While in Nvidia GPU only mode, the same procedure allows me to actually switch to 60 Hz.

I tried wiping the GPU drivers with Display Driver Uninstaller (DDU) in Safe Mode, then installing Lenovo-provided drivers afresh, but this didn't help.

In CRU I can see three options for monitor selection. One for Hybrid mode, one from Nvidia-only, and one is just called Generic and I can't see it active in neither of GPU modes. I tried adding the 60 Hz preset in all of them, still no luck.

Do you have any ideas what should I check now? Maybe I need to collect some logs and provide them here?

Thank you!
