Hi, I’m facing a similar issue as well. I’m using the Framework Laptop 13 with AMD 7840U. My Dell external display doesn’t always extend my screen when connected to my laptop via USB-C on ports 1 and 3 (USB4 ports).
I’ve tested a few scenarios, there are only 2 scenarios where I can use my external display with my framework laptop. 1) When my laptop has 95% and above, or 2) When I have a power source charging my laptop on a different port. When I’m in either one of these scenarios, then my framework 13 can charge and project/extend to the external display at the same time. Else it will show an error message at the bottom right corner “Display connection might be limited”. The laptop will attempt to project/extend to the external display when connected. The screen on my laptop will become smaller during the attempt to connect to the external display and maximize back to full size. But the external display will remain blank, and my framework laptop will try to project/extend to the external display again repeatedly.
I’ve tested it with different laptops, cables, monitors, the latest drivers, updates & BIOS 3.05, but the issue persists. Has anyone found any other way to solve this issue?
