ASUS P8P67 Deluxe B3 motherboard
XFX Radeon HD 5670 512 MB Video card
Vizio 37'' 720 HDTV

I am able to see only 40% of ASUS P8P67 - BIOS screen. Rest of the screen is cut off/scrambled. I am using HDMI cable to connect Video card & TV. Luckily I was able to change the boot options as those are visible.

Once OS boots, I am getting a perfect HD output. But somehow BIOS screen is not appearing correctly. I could see only Top Left portion.

Any help on how I can view the complete BIOS screen will be helpful.

Thanks.
