VRR support missing on AOC 24G2W1G4 with drivers 32.0.101.6127 and later

[canadagoose]

Hello, I'm currently using an Arc A750 with the latest drivers 32.0.101.6130 (10/29), connected to an AOC 24G2W1G4 monitor with FreeSync enabled over Displayport 1.2. 

Previously, Arc Control supported Variable Refresh Rate between 48Hz - 144Hz for monitor with driver versions 32.0.101.6083 (10/7) and earlier.

However, Arc Control no longer supports Variable Refresh Rate for my monitor after driver versions for driver versions 32.0.101.6127 (10/18) and later.

Here is a list of driver configurations I have tested:
32.0.101.6130 (10/29, latest): No VRR support

32.0.101.6129 (10/24): No VRR support

32.0.101.6127 (10/18): No VRR support

32.0.101.6083 (10/7): VRR supported (confirmed twice)

32.0.101.6078 (9/24, WHQL Certified): VRR supported

To reproduce the issue, all I need to do is update the Intel Arc driver version from 32.0.101.6083 (10/7) to 32.0.101.6127 (10/18) using a clean installation. I can also reproduce the issue in the reverse direction by downgrading the driver version.

SSU is attached.

Hello canadagoose,

Thank you for posting in Intel community Forum.

For me to further check this, please help provide the following details:

1. Are you using an Intel brand Arc A750?
2. If you will rollback the drivers, can you still enable Variable Refresh Rate?
3. Aside from the drivers, what are the troubleshooting steps that you tried?

If you have questions, please let us know. Thank you.

Best regards,

Hi Michael,

1. Yes, I'm using an Intel Arc A750 LE.

2. Yes, if I rollback to an older driver (32.0.101.6083 or earlier), Arc Control allows me to set VRR to "enabled" for the monitor. If I switch back to a more recent driver, Arc Control returns to saying "Not Supported."

3. I have not tried additional steps aside from rebooting the PC between each driver installation (clean installation) and powering the monitor on/off. The monitor settings and hardware configuration remain the same between runs, only the driver version changes.

Thanks.

Hello canadagoose,

Thank you for the update.

Can you try the Graphics Driver 32.0.101.6299? You can download it here:

https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html

If you are still having the same issue after trying this driver, please generate another set of SSU using this driver.

If you have questions, please let us know. Thank you.

Hi Mike, I installed the latest drivers 32.0.101.6299 and the same issue is present.

I've attached the updated SSU using this driver.

Hello canadagoose,

Thank you for the update.

Can you try the Graphics Driver again however this time using the clean driver installation method using DDU?

Hi Mike,

I performed the following procedure:

1. Reboot PC to Safe Mode
2. Use DDU v18.0.8.8 (latest) to completely uninstall Intel Graphics drivers and previous GPU drivers
3. Reboot PC to standard mode
4. Install Intel Arc Drivers 32.0.101.6319 (latest)

However, Arc Control still displays Variable Refresh Rate as "Not supported" for the monitor:

I've attached a new SSU report as well.

Thanks
