Hi Group:
I have an Asus brd with a NVidea on board video.
When I have had two different HD TVS connected via the HDMI cable. (I have also used an HDMI cable with opto-couplers), the computer refuses to boot, shows the blue screen of death and shuts down.

I can disconnect the HDMI cable from the TV, and my system boots normally. I then plug in the HDMI cable to the TV and can operate in clone mode.

Any suggestions?
Joe
