    I have set up a dual-monitor set up with an Acer 22 inch monitor as my normal monitor. I have been attempting to use my 19 inch Toshiba LED TV as the secondary monitor. Earlier this week, I had a PSU problem. I replaced the PSU and re-set the BIOS. Now my TV is the monitor that displays the POST boot screen.

    Acer monitor is on the "top-most" DVI connector (new the card to case screw-down.)
    Toshiba TV is on the bottom most DVI, with HDMI adapter.

    Does anyone now which is the primary DVI port (for the POST boot display "connector?")

    The one closest to the motherboard/PCI slot.

    Usually and when in doubt, just switch. Had the same problem once, switching them solved it.

    I've swapped them. Now nVidia Control Panel is stating my Acer is connected vid a "Composte" connector, with S-Video option avalible. I can not statin DVI.

    The Toshiba TV is still listed as HDMI on the second "top" port.
