Latest Intel Arc A770 driver update forcing 1440p monitors to run at 1080p

I have an Intel Arc A770 - 16GB and I have just installed the latest driver 31.0.101.4826 and it has caused a really strange problem.

My BenQ GW2765 monitors which run at 2560x1440 are now being forced to run at 1920x1080.

I have a taken a look at the device manager and under the previous driver 31.0.101.4577 they were showing as BenQ GW2765, now they are showing as Generic Monitors.

I cant roll back this driver and there is no update available - I have also looked online and there is no driver on the BenQ support site - If I remove the latest Arc drivers and revert back to the previous version the monitors display correctly in device manager and at the correct resolution, so it IS an issue with this driver update.

 

Help.

Rob

 

EDIT: I'm using DP cables, when I switch to the HDMI cable the normal resolution and driver behaviour returned so Its possibly DP cable related, ill continue tests.

Edit #2: Using Display port to HDMI converters seems to have resolved the issue for now, however, I shouldn't have to use these devices to get basic functionality of this card. I accept part of adopting new tech is accepting disruption. The DP cables I was using were both DP 1.4 so no issues should be present since DP 2.1 is backwards compatible. I suspect something in the Firmware update or software driver update has altered the way DP behaves (at least that's how it feels) I couldn't find anything explicate in the patch notes so I'm still unsure as to the cause of this issue.

 

I will periodically try the DP cables after subsequent updates to see if any attempt to fix the issue has been made.

@Andres_Intel 

This is a very known issue, and has been numerous forum posts regarding this issue.  This affects me too.

I'll list some forum posts that have the same issue collectively here as we are all waiting for a response from Intel on this issue.   Currently we are still fighting for the issue to be addressed in Known Issues on the display driver release notes so as to help people such as this OP not waste time troubleshooting the issue and feel reassured that it is being actively worked on.   

I've now had this issue for two months and no real official response that it is being worked on.   Can you please provide some feedbackup on the issue.  

 

Many thanks

Paul
