EVGA 8800GT Post/Boot Resolution

Recommended by Wim's BIOS...

Hi all,

I'm hoping someone here can shed some light on my problem. I'm using an 8800GT from EVGA. Previously I had an 7950GT. It's connected to a Denon 3806 HDMI A/V Receiver then to my projector. My problem is when I upgraded to my 8800GT, it doesn't seem to display the boot/post/bios screen at a resolution that my receiver or projector accepts. With my previous 7950GT, it would display at 640x480 or 1280x720, but the 8800GT output at post will not synch to my projector. Is it possible to edit the 8800GT's bios to force a specific resolution at bootup?

Thanks!
