Thanks. I'll wait till Egbert is back.If it helps in any way, the
motherboard Asus M2A-VM has only two output VGA and DVI. It comes with
an add-on board that add HDMI, S_video, Digital audio out. However,
the HDMI output is disabled in BIOS by default. I don't use it. The
screen is blank if I connect my Monitor to it.

Also, I have only one monitor, Gateway FPD2275W. It's connected to the
computer using both DVI and VGA cable. Only VGA works properly. DVI
displays 1280x800 resolution. How do I force DVI_D 2 output to it ?

Thanks,

Toan
