UHD 630 Dual Screen Issue

[Diozza]

I have a Lenovo PC with an Intel UHD 630 dual screen card running Windows 11. It used to be fine, but now every time I 'wake up' the PC the right hand screen comes up utterly unreadable... lots of fuzzy lines, etc. If I unplug the displayport cable from the PC for the right screen, and reseat the cable, it comes back fine. I have to do this every time. Any ideas what is causing this?

Hi Diozza,

Thank you for posting in our Community and sharing the details of the issue you're experiencing with your dual-screen setup using the Intel® UHD Graphics 630 on your Lenovo PC. I understand how inconvenient it must be to reseat the DisplayPort cable every time you wake the system from sleep just to restore proper display functionality. To help us further investigate and identify the root cause, could you kindly provide the following information:

• What is the brand and model of both monitors you're using, particularly the one connected to the DisplayPort?
• Can you confirm the type and version of the DisplayPort cable (e.g., DP 1.2, DP 1.4)? Have you tried using a different cable to rule out a faulty connection?
• Is the monitor connected directly to the motherboard or through a docking station or adapter?
• What is the current version of the Intel graphics driver installed? Have you recently updated or rolled back the driver?
• Are both monitors set to the same refresh rate and resolution?
• Are you using any custom power plans or sleep settings that may be affecting display behavior on wake?

I'd like to delve deeper and verify specifics like the graphics models, precise driver versions, and any system errors. Utilizing the Intel SSU tool will enable me to collect detailed information about your system setup, which could aid in identifying the underlying cause of this issue. 

Have a nice day!

Best regards,

Hello Diozza,

Thank you for providing the details regarding your setup, including the monitor model, connection type, driver version, display settings, and power configuration. This information is very helpful in narrowing down the possible causes of the issue.

Upon reviewing the Intel SSU logs, I noticed that the Intel® UHD Graphics 630 driver appears to be outdated. I recommend updating to the latest version, 31.0.101.2135. I also suggest using the Intel DDU tool to perform a clean installation for optimal results.

Have a nice day!
