Mobo : ASUS Pro A520M-C ii/CSM CPU : AMD Ryzen 5 4600G w/ Integrated Radeon Graphics OS : W11 PSU : 500W BIOS : Most recent for MoBo (can't recall exact version number) When linked to VGA, the system starts without issues and boots fully normally. On HDMI it starts but emits a long series of three short beeps, which I interpreted as a GPU or memory fault; after that it boots and displays a desktop at around 600x600 resolution. I replaced the RAM for safety and updated the BIOS to the latest release, but graphics drivers remain unresponsive. I’m struggling to locate anything in the BIOS settings and would prefer HDMI availability over VGA.
Run PowerShell or CMD as admin. The system info will display extensive details about your mainboard in the BIOS version. No external software needed. VGA supports resolutions beyond 800x600, but a compatible driver is required. It’s unclear if HDMI follows the same rule.
