Ryzen 2200G on an MSI B350M, latest bios and drivers. HDMI port only outputs 4k signal to 1080p monitors prior to OS coming up. VGA port works fine and syncs at 1080p. HDMI output was fine with the A6 loaner CPU provided by AMD but the Ryzen will not sync correctly. Tried on two monitors from different manufacturers with same result. Makes is impossible to get at BIOS with a 1080p monitor. MSI support isn't getting me any where. Could this be an issue with the cpu?
