I actually have this issue on a both of the 1L machines I recently got. The other is a ThinkCentre m75q-1.
The issue is with display port, whenever I am using display port for my display it flickers on the screen. Not a full on and off to complete black. Basically the lower half every other second it glitches, I am not sure how to describe it, I could upload a video if that is an option here. Luckily I am using these for servers so I do not really need a display for them. When I set up the Lenovo, I did try HDMI since I had that option on that unit, and there was no flickering at all. But on the HP unit there is only 2 display ports. I have tried to install an older version of the bios, but this didnt work. I have tried to uninstall the display driver via device manager on windows 11. Nothing has corrected this issue. Another note is that when I boot to my Ventoy USB drive it still flickers, so I do not think that it is an OS issue. There is no GPU, its just an IGPU from the ryzen 5 PRO 3400G.
The instances that it is happening is weird, considering it seems to be contained to displayport, and its on both of the units. I have used multiple cables and monitors to no avail.
Again, since I am using these for servers, this issue does not really matter for me. But I would like to figure it out and fix it so that in the future if I decide to use these for something else, I can without the display issue.
Any help would be appreciated. This is my first post here, and I did not see a help section. So I am just posting here.
