Description

NVIDIA Open GPU Kernel Modules Version

515.48.07

Does this happen with the proprietary driver (of the same version) as well?

Yes

Operating System and Version

Arch Linux

Kernel Release

5.18.1-arch1-1

Hardware: GPU

NVIDIA GeForce RTX 2060 (UUID: GPU-27024b8f-ce0b-2546-7f78-676a22fa9c42)

Describe the bug

When I set the resolution to 75 hz my monitor says input not supported. this is because my monitor is only capable of displaying exactly what is shown in its edid. I am using an acer sb220q bi. this issue first occured in the proprietary drivers with the 510 line. not entirely sure why this is, but im more than happy to provide an additional information.

To Reproduce

connect an acer sb220q bi (or likely other acer monitors that lock the resolutions to whats in the edid), and set the resolution to 75 hz.

Research direction

Start by reproducing the issue with the Acer SB220Q BI at 75 Hz on the stated NVIDIA driver and kernel versions, then review nvidia-bug-report.log.gz for the reported mode and EDID details. Done means the driver no longer selects or passes a 75 Hz mode that the monitor rejects, while supported EDID modes continue to work.
