Been trying for a little over a week now to achieve a dual monitor setup. What I have found out is that my motherboard's onboard video does not work when I have a monitor plugged into my video card. I have tried configuring the BIOS, but, nothing. If anyone can help, it'll be greatly appreciated! Thanks,
When you add a gpu, your motherboards onboard graphics is disabled (unless you have one of those mobos that support integrated graphics) & you must connect both monitors to the new gpu. You should then be able to configure your 2nd monitor through windows control panel.
