Hello,

I've recently purchased a TV to connect my PC through, however my old GTX 570 couldn't support dual monitors AND an HDMI connection, so I've purchased a GTX 770, however now I'm having issues with the second DVI monitor connection.

On the GTX 570, both monitors and the TV were displayed in the multiple displays area in Windows 7, however it would just not allow me to run 3 monitors.

On the GTX 770, only one DVI monitor (in the top plug slot) and the TV through HDMI are displaying. The second DVI monitor just isn't showing up. It's not in device manager either.

I've swapped the monitor connectors and both of them work, so it just seems to be the bottom slot on the GTX 770. Unplugging and plugging it back in makes the second monitor display 'No Signal'.

Does anyone have any idea what might be causing this and a possible solution? Any assistance would be greatly appreciated.

I am going to suggest it doesn't help you whatsoever, but I have the same problem with a brand new GTX 770, but it's the DVI-D slot (the top slot) that isn't working.

My old card (8800 GTX, yes, it's been a while since upgrade!) displayed two DVI outputs easily. However, the 770 doesn't seem to. Which is annoying.

I've had a good look around but can't seem to find any solutions yet.

Just replaced the 770 with the old 8800 and both monitors worked fine automatically, extending the desktop across them both without even having to lift a finger. It must be a 770 GTX issue, although I'd be surprised if it's a card fault?
