Threaded Mode | Linear Mode

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!

Help in CSGO I don't have 1280x960 resolution , but I want to play with it, so tried to add this by CRU . But when I do this , I have black screen in CSGO , how can I play with 1280x960 , may be someone know???

Laptop: Huawei matebook d15 with AMD
IN AMD software , I can't create a new resolution.

Laptops can't display non-native resolutions, so you have to either enable GPU scaling in the Radeon software, or use Scaled Resolution Editor.

That sounds like a graphics driver bug. If Windows lists 60 Hz but it acts like 144 Hz, then CRU added it correctly, but the driver is not switching refresh rates when you change it. I haven't seen many laptops with AMD/NVIDIA switchable graphics, so I don't know what limitations they have. Usually it's Intel/NVIDIA, and in that case, Intel's driver would be responsible for the resolutions, so this might be a bug in AMD's driver.

I've tried making 60hz the minimum in the "range" at the top of the CRU window. I also removed all resolutions with a frequency below 60hz. However the 24hz minimum is STILL shown by Windows. Where is it coming from ? I'm pretty sure its not in the EDID anymore so my guess is that AMD (or Windows) is automatically adding it. Is there any way of stopping this ? Cheers.

I haven't heard of AMD drivers automatically adding 24 Hz. Are you sure it's not in the EDID? Check the HDMI data block in the CTA-861 extension block.

Hi, I have a problem with a monitor that supports UHD 144Hz only via connecting 2 display port cables: I got this mode to work somewhat, but the monitor shows artifacts (interspersed lines).

Since I already had to create a custom resolution for 120Hz to work (it didn't work for the default 119,91 that windows selected), I thought maybe 144Hz also has a problem with the default 143,839Hz that are selected by Windows. But the Nvidia Customize option is greyed out for the dual-displayport-cable mode.

I tried CRU to create a suitable mode with 144Hz, but the mode becomes red and can't be saved, maybe I'm doing something wrong.

Strangely enough, the only mode available in the EDID seems to be:

Code:

Native/preferred timing.. 2000x1000p at 60Hz 

    Modeline............... "2000x1000" 166,250 2000 2128 2336 2672 1000 1003 1013 1038 -hsync +vsync

Any idea what I could try?

Thank you @ToastyX !
I'll try to reach out to AMD or Lenovo then...

Hi! Can I add 1920x1440 resolution on my laptop with full hd display? Or It will not support and can break my window down ?

Either your monitor is adding black bars, or the resolution is GPU-scaled and set to add black bars.
