I ran into an issue with my server where my Yamaha TSR-5810 (RX-V581) receiver connected to an Optoma projector would display a blank screen during the POST/BIOS phase. I immediately suspected that HP’s BIOS couldn’t handle the low resolution of 720x480 reported by the projector, with the main suspect being the vintage DisplayPort to HDMI 1080p converter I was using. The immeddiate diagnosis was that the HP’s BIOS couldn’t handle the low resolution of 720x480, as reported by the projector, and the main suspect was the vintage DisplayPort to HDMI 1080p converter I was using.
