Hey everyone,

I've just built a new computer and fitted it with a lovely Nvidia Palit Geforce GTX 450 video card (ebuyer page).
It sports two DVI ports, 1x HDMI and a VGA. I've got my main monitor plugged into the VGA for now but when I plug any monitor into either of the DVI ports, although it registers on the computer that the second screen is there, the monitor displays nothing. Any ideas why this could be?

Thanks

Josh

You may have to toggle the input source on the monitor. Not all of them will automatically input from a DVI input. They should, but they don't always do it.

While not free, there is no better multi-monitor utility than UltraMon.
