Hello Intel,
I have a Lenovo Thinkpad T15 gen 2 with a upgraded/replaced 4K internal display. It has an Intel Core i7-1145G7 with iris Xe graphics. The problem did not occur with the original 1080p display.
When the laptop goes to sleep either by closing the lid or selecting the sleep option in the power menu upon waking back up the internal display becomes corrupted. I have determined that this is an Intel video driver issue due to the following tests I have made:
1. The problem does not occur in Linux or in the BIOS (Lenovo Diagnostics)
2. When the Intel video driver is uninstalled and the display adapter uses the Microsoft Basic Display Driver the laptop wakes up from sleep without display corruption.
This display corruption only occurs on the internal display. External display is not effected. The corruption in particular makes the display image show an RGB striped vertical texture with an out of scale image of the interned display picture. See attached photo. Only after a reboot will the display go back to normal. I have tried to reinstall the intel driver from both Lenovo's website (version 32.0.101.5972) and from Intel's website (version 32.0.101.101.6253). Both results in the same problem.
This same problem also occurs when attaching an external display to the laptop. Either duplicating the display or extending it causes the corruption to start again.
Brand and Model of system: Lenovo Thinkpad T15 Gen 2 (Type 20W5)
OS: Windows 10 64bit 22H2

Hi Charles2000Wang,
Thank you for posting on Intel Community Forum.
I understand that you are having issues with the display of your Lenovo ThinkPad T15 laptop. I would like to get the details below for me to get the bottom of this.
1. Did the OEM perform the upgrade/replacement of the internal display?
2. Have you contacted the OEM since the issue only occurred right after the upgrade of internal display?
3. Did you use Display Driver Uninstaller before installing the driver?
Additionally, to have a better understanding of your system configuration and components please generate System Support Utility (SSU) report. Please follow instructions here and send the report - How to get the Intel® System Support Utility Logs on Windows*
I'm looking forward to your response.
Best regards,

Hello Jed,
I was the one who replaced the internal display to replace the original 1080p display which was broken due to physical damage. The display I installed is BOE NE156QUM-N66 V3.0 which is physically and electrically compatible (uses eDP 40 pin connector). I have contacted the OEM but they where unable to solve my problem. They suggested to install their version of the video driver (version 31.0.101.4255) but still have the same issues. We have also tried to reinstall Windows (both 10 and 11) but that also did not work.
I have used the DDU program from guru3d.com when uninstalling the video drivers.
I will make another post with the System Support Utility (SSU) report shortly.

Hi Charles2000Wang,
I am following up on the investigation I conducted. For further troubleshooting, please follow these steps:
1. Update the BIOS to version 1.64/1.16 by downloading the BIOS Update Utility (Windows) from the Lenovo website.
2. Update the graphics driver to version 32.0.101.6449_101.6256 WHQL Certified (Latest).
If the issue continues, please reach out to your OEM once more, as the problem originated following the replacement of the laptop's internal display.
