Hi Luca Conconi
Thank you for posting in Microsoft Community.
From what you wrote, I understand that you are facing a problem with your Surface laptop 4 where the Intel Iris Xe Graphics fails to launch.
Let’s work together in finding the best solution to this issue. to get started, I will ask a few questions to further isolate the issue.
- Can send a screenshot on what happen regarding the resolution on the external screen?
- May
- How you connect the Surface device to Second screen through wired connect or Wireless through Miracast?
- We would like to know what version on your Intel(R) Iris(R) Xe Graphics-Display if the version is already 31.0.101.4502?
- If the version is already 31.0.101.4502 try to rollback, then see if the issue persists.
From what you told me, the Intel Iris Xe Graphics might have a hardware defect. But before you decide that it is a hardware problem, you can attempt to download and install a USB recovery image on your Surface device to make sure that it is not caused by software.
If the problem still exists even after we reinstall the recovery image on your Surface device, then it means that there is a hardware defect on the device’s Graphic display. You will have to either fix or replace the device.
