Driver Version .4644 Problems with dual Monitor Setup.

[ELehner]

Hello!

I have currently two monitors connected to one of two ARC 770 Cards. 
With the driver update .4644 the second monitor on displayport cable is not correct detected. 

The monitor is HPZR2740w with max resolution of 2560x1440. 
The driver and Windows only detects 1980x1040. 
Also there is no image displayed on the HP Monitor. 

The monitor name is also not detected. 

After reinstalling the old .4577 Driver everything is working again. 
Important! users with simmilar problems ... USE good monitor cables!
After first installing the Monitor with the .4577 drivers i had only a DP to DVI Cable.
With this cable the ARC 770 was not able to detect the monitor correct.
After changing the cable to a good one the setup works with dual monitor. 

This is also true for my main monitor connected via HDMI cable. 
Changing to a highend cable removed strage glitches from my screen. 

I use two Arc 770 Cards.

This a real speed boost in Blender since ver. 3.6.
Also making 360° Videos in UE5 works great because i have now 32GB Video Ram.


Please compile a Driver where the Blender crashes are removed(4644) and multi Monitor is 
working(4577).

Greetings:

Erich

Hello ELehner,

Thank you for posting on the Intel®️ communities. I see that you are having display issues with your second monitor while using Intel® Arc™ A770 Graphics, I will be happy to help you.  

Please open a new thread for the Blender crashes issues, to keep the threads organized, as it is not related to the monitor issue.

To have a better understanding of the situation, please answer the following questions:

• Are the two monitors HP ZR2740w? If that is not the case, what is the other monitor's make and model?
• Are you using adapters or docking stations? If so, what is the make and model? We recommend not to use them.
• To check if there are pending updates on your system download, run, save and attach the report for the following tool Intel® System Support Utility for Windows (SSU), you can find the steps on the link How to get the Intel® System Support Utility Logs on Windows.
