Hardware: GPU

GPU 0: NVIDIA GeForce RTX 5090 (UUID: GPU-442c0ed9-c471-c189-183d-38f407d07985)

Describe the bug

Running a LG 45GX950A monitor at 5120x2160 using HDMI at 165Hz results in a corrupted (snowy) output. Tested on Sway and Hyprland.

This is fixed by dropping down to 100Hz.

This issue does not occur in Windows.

DisplayPort works fine.

To Reproduce

Connect 5090 GPU to monitor via HDMI.

Set resolution to 5120x2160 and refresh rate to 165Hz.

Hi @hwchong, we made a number of HDMI FRL related enhancements in our kernel modesetting driver. We should have this out in a future driver. Would you mind if we retest once that driver is out?

[hwchong]

Sure, please let me know when the update is pushed.

Still broken as of 580.82.09

Unfortunately, the related HDMI FRL fixes did not make it in that release.
