Hi guys,
Recently bought myself 3 new monitors, all work fine. I have 2 plugged into my graphics card, and the other into my mobo.

■ Graphics car = Nvidia Geforce GT 640
■ Motherboard = Asus P8Z77-V LX
■ Onboard Graphics = Intel HD Graphics 4000

My problem is, I want to play the same game on all three monitors stretched across, but Nvidia Control Panel will not find my third monitor which is plugged into my mobo - only the two plugged into my graphics card. What can I do?

Thanks a lot,
Dave

You don't understand, there is none, not only these are two different graphics cards, they are also two manufacturers. You could try and make a functional driver yourself, I'll even lend you my programming e-books. You should be able to learn enough to whip something up in... say 5-10 years.

Cards capable of 3 video exits are only enthusiast grade or higher. Maybe if you buy a super expensive card which aged gracefully on ebay for a low price, I don't see how you are going to fix this problem without a major pc overhaul.

That is not at all true. I'm using 2 monitors myself, but neither has HDMI slots, unfortunately, so I need to use the VGA slots, but there is only one on my Asus GeForce GTX 750 Ti, so I had to use the mobo (Asus Z97-K) VGA slot for the second monitor... When I built my PC, I never bothered installing the graphics driver for the system, because I used my GPU as my video output, so naturally when I plugged in the second monitor, into the mobo, nothing happened, but once I installed the graphics driver for the motherboard (a disk comes with the motherboard, your drivers are on it. if you didn'T build yours, just do a Start > Run > "dxdiag" (without quotes) and find what motherboard/graphics unit you have, and download the appropriate driver(s). For you, Dave, its Intel HD Graphics 4000, you already got it) then install the driver, restart the PC, plug in the monitor, and voila.. it works.

I'm personally using 2 ancient monitors, because 1, the main monitor, I've had before I built my PC, and the second is an pretty crappy one, but it matches the resolution (digital and physical size) of my main monitor, 1440*900 pixels, they synch well. Only my main monitor is plugged in to my GPU, and the secondary is plugged in the mobo.
