Problems of graphics drivers in using DP Interfaces

[zkx1202]

Hi DeividA_Intel,

Thanks for your Recommendation. I am sorry for my poor English. I post this new question, because I can not reply you in the Discussion post on ‎08-03-2023 (https://community.intel.com/t5/Graphics/Problems-of-graphics-drivers-with-compatibility-for-display-port/m-p/1510880).

Q1: How many monitors are you using on your computer? This is just for me to have a better view of your environment.
A1: I have only one monitor on my computer. I use i7-12700K CPU and Arc-770 GPU. The attachment is the information of my computer.

Q2: Is the issue present when you use two Display ports at the same time in the Arc GPU? And, does that issue disappears when the HDMI is connected to the board and the Display Port in the Arc GPU? I just want to make sure that I am understanding correctly your issue.
A2: The issue present with try three DP Interfaces in the Arc GPU and also occurred with DP Interfaces in the matherboard at the same time. But the problem disappears when using HDMIs in both the Arc GPU and the matherboard.

Q3: If possible test the latest graphics driver (31.0.101.4577). Just to make sure if this behavior is also present with this version. Make sure to use the "clean install" option.
A3: I have test the latest graphics driver (31.0.101.4577) and all previous graphics drivers. This behavior is also present with those versions.

This problem disappears when connecting with HDMIs, using Microsoft Basic Display Adapter, turning on HDR display in the Windows11 or switching DP Interfaces to DP 1.1 compatibility mode. Besides, when using the graphics driver 30.0.101.1960 for UHD-770, the monitor works well with the DP Interfaces in the motherboard. I find this solution for UHD-770 by Bing. Will future drivers resolve the problem with DP Interfaces?

Hello zkx1202,

Thank you for the information provided. We understand that you created another thread since you experience a problem responding to your original thread. We will contact you through the e-mail address associated with your community profile to continue our conversation in case you can't reply to this thread.

You mentioned that you tried using different DP ports; however, we would like to know if you connected a device to the DP ports, all at the same time, or if you used the different ports one at a time.

We also would like to know if you are able to try a different Monitor, or connect the same monitor to another system, and check if you can replicate the problem.

Furthermore, we would like to recommend you run the Display Driver Uninstaller. Check How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver for instructions. Once you run the tool, you should install the latest driver from Intel driver, 31.0.101.4577. The DDU tool will eliminate all drivers and leftover files from previous driver versions.

• We would like to gather more information about your system. Please create a system report using the following tools:
• Intel® System Support Utility (Intel®️ SSU) 
  • Open the application and click "Scan" to see the system and device information. By default, Intel®️ SSU will take you to the "Summary View."
  • Click on the menu where it says: "Summary" to change it to "Detailed View."
  • To save your scan: click "Next"; then "Save."
• Intel® Graphics Command Center:
  • Open the Intel Graphics Command Center
  • Navigate to the Support tab
  • Select System Diagnostic
  • Click Generate Report
  • Select Save and name the output file.

Best regards,

Hello zkx1202

Before we close the case, we want to confirm your monitor's make and model to further research this problem.

However, it is important to mention that since the issue occurs with both integrated Graphics and the Intel® Arc™ A770 GPU then it is unlikely a hardware issue.

Best regards.
