HDMI TV Not displaying BIOS\Boot Screens
Strange little problem from the home this one. I have a media center PC running Vista Ultimate 32bit edition and a Gigabyte GA-73PVM-S2H motherboard with an onboard GeForce 7300 HDMI chipset. This worked fine when displaying boot and BIOS screens. I then fitted a GeForce 8500GT PCIe graphics card with HDMI out.
Now I can't see the boot\BIOS screens and only get to see the screen once Windows loads the drivers (the latest 169.25 release) and then it is fine. I can see the BIOS and boot screens if I connect the optional DVI output to the VGA port (via an adapter). The original on board graphics are disabled in the BIOS and Windows logs no unusual problems during booting.
Anyone have any hints?
