Intel(R) Graphics / Intel Arc(TM) Graphics both update driver to latest cannot show QHD timing

[ThomasYao]

Hi,

My notebook is an HP EliteBook 640 G11 with Intel® Graphics.
I'm using an HP QHD monitor (527pq) connected via the HDMI port. With the recommended resolution, it correctly displays 2560 × 1440 @ 60Hz using the original driver.

However, after updating the Intel graphics driver to the latest version (32.0.101.6653 / 32.0.101.6651), the maximum available resolution is only 1920 × 1080 @ 60Hz.

After rolling back to the previous driver version (32.0.101.5768), it can once again display 2560 × 1440 @ 60Hz properly.

Could you please help inform the driver team to investigate this issue?

Thank you.

Hello ThomasYao,

Thank you for reaching out to the community with your concern.

To better understand the situation, could you share the steps you followed to update the drivers on your computer? If you installed Intel’s generic drivers, they may have overwritten the custom features provided by the OEM.

Additionally, have you tried using a different HDMI cable to see if the issue persists?

Hi,
I’m using the same HDMI EDID and the same HDMI cable, and everything displays correctly with the older driver version.
The issue only occurs after updating to the latest graphics driver.

I’m not sure why I would need to try a different cable, as the current one works fine with the previous driver.
However, I did find that if I change the HDMI EDID from CVT-RBv2 to CVT-RBv1, the display works correctly even with the latest driver.

Based on the tests above, it seems the latest driver may not fully recognize all CVT-RBv2 timings.

Please help forward this to the driver team for further investigation.

Hello ThomasYao,

Thank you for your response. The reason I suggested testing a different cable is that, in some cases, HDMI can impact display resolution.

Moving forward, I will investigate this issue internally. Please allow me some time to look into it, and once I have a solution, I will provide an update through this thread.

Hello,

Updating the status here to help others who might encounter the same issue as mine.

Jed Allen performed remote access on 4/10. We updated the driver from the old version to the latest version to verify the issue. He will reply to me on 4/15 with further findings.

I have also sent the SSU report and EDID txt via email.

Thanks.
