Hello world! 
I’ll throw some specs at y’all first:
System: Framework 16 with AMD Radeon RX 7700S
OS: Windows 11 Pro 24H2
Monitor: iiyama G-Master GCB4580DQSN
When I connect the FW16 to the monitor, I see the desktop shrink briefly, but then things stutter a bit, and eventually nothing happens. It’s like it detected the monitor, tried to send the display information, but failed.
I have tried this with HDMI, DisplayPort, the USB-C cable that came with the monitor, the official USB-C cable from my Nothing Phone, and a rather expensive new USB4 Gen 3x2 USB-C cable to ensure the highest standards are available. Unfortunately, none of these options work. On the monitor side, I see it turns on, but then states there no signal found, and turns off again, no matter which input is selected. I would like to make use of the built-in USB-C dock that is in the monitor, which was one of the main reasons I chose this one.
The strange thing is: when I connect to a HP USB-C G2 dock, and then connect the monitor to the dock, the setup works! When I then take a peek in device manager, I see the screen is detected as “Generic Monitor (PL4580DQ)”, and it’s driven by the AMD Radeon 780M. In display settings, its resolution has 5120x1440, and supports up to 120 Hz (it’s advertised as 165 Hz).
I don’t really care for the refresh rate difference, but I would like to eliminate the need for the HP Dock. Why is it working via the dock, but not when the Framework is connected directly? The monitor does work when connecting a HP Zbook directly. Any help would be much appreciated! Thank you for your time.
