I am using a Alienware AW3225QF monitor that can run (on Windows) with the following settings in the Nvidia App: 3840x2160 resolution, 240hz refresh rate, 12bit color mode However, on Linux, whenever I use HDMI 2.1, I seem to have a strange issue that happens only after the monitor has been in slee…

This is also happening to me. Willing to provide logs if needed. Running Driver Version: 580.95.05 with RTX3070. Also on HDMI.

Still an issue. Driver 590 via CachyOS. 240hz gets stuck at 60hz until I turn the monitor off and on or reboot. Happens regardless of distro, DE etc. Using Wayland on HDMI 2.1

Hi All, Please ignore the earlier mentioned bug tracking number, it turned out to be a different bug. I have filed a new bug 5801388 for it. Hi @dhfragged @VirtualBoost_v2 @StarMech67 Will be really helpful if you can share nvidia bug report from repro state along display model.

Hi @amrits , I believe that my initial attached files should cover this, my monitor is a AW3225QF. Can you confirm?

Dear @VirtualBoost_v2 I was able to find exact same display in our lab but unfortunately not able to reproduce issue. I have tried suspend/resume operation around 5 times and kept system in suspended mode for 20-30 mins. System - ASRock TRX40 Taichi OS - Arch Linux with kernel 6.12.63-1-lts GP…

Hi, If it helps, I am still experiencing this issue, albeit with a different monitor. This has been an issue for months now and I have not received any kind of feedback from my bug reports. System/Motherboard - ROG STrix Z690-G Gaming Wifi OS - Bazzite (latest build) GPU - NVIDIA GeForce RTX 4090…

I have the same problem like @dhfragged , first posted here . In addition, the 240 Hz mode appears to be unstable. Sometimes the monitor loses connection and has to be reset to factory settings in order to work again. This problem does not occur in 120 Hz mode. My System: OS: CachyOS latest GPU: N…

Hi @amrits What I do is lower the time when KDE puts the monitor into sleep to 1 minute, and then I wait for it go to sleep. Another way is just locking your PC, then press ESC on the login screen to force it go to sleep. Finally, I wait until the on/off-button starts blinking white, so I know that…

Hi @VirtualBoost_v2 I installed Cachy OS with kernel 6.19.2-2 but did not observe repro. Setup - ASRock TRX40 Taichi + CachyOS + kernel 6.19.2-2-cachyos + NVIDIA GeForce RTX 4090 + 590.48.01 + Alienware AW3225QF monitor with 3840x2160 resolution and 240hz refresh rate connected via HDMI 2.1 + KD…

I’m having the same issue with the same builds, except with a Samsung GS80D 4k 240hz. It seems intermittent, but most of the time if the monitor sleeps due to PC sleep, monitor off, or just turning the monitor off it will sometimes lock at 60hz with no way to return to 240 unless I reboot or unplug/…

I’m experiencing the exact same problem on Fedora 44, and it is still happening with driver 595.71.05.

System: Fedora 44, KDE Plasma Wayland, RTX 3090, Samsung Odyssey G9.
