Windows 8.1 with Dual Dell Monitors Issue

Hi all,

I have been working with Windows 8 and a single monitor for months now, I bought a second monitor today and it doesn't seem to want to work.

So the first main monitor I have is a Dell u2711 27-inch, the second which I bought today is a Dell 24" U2412M Widescreen.

When I plug in the second monitor, I get booted to the Windows 8 login or 'welcome' screen. I am asked for my password. While on this screen I can quite happily move my mouse over to the next monitor and all appears to be fine. But I pop in the password, press enter and then i'm booted back to the login screen.

The second monitor flashes blue after hitting enter.

My graphics card is: Gigabyte GTX 760 OC Windforce 2GB.

Something to note is that my 27" monitor uses a dual DVI link connection, whilst the secondary 24" uses a normal DVI connection. I thought it was something to do with this at first but I'm not entirely sure now.

Thank you for any help in advance!

go into windows display options and setup the second display ad desktop extended.

try the windows key + p and change to extended as an alternative, not sure if this works still in windows 8

Yea that's totally what I'd normally do, but as I say it won't let me get on to the desktop to do this, it keeps kicking me back to the login/welcome screen.

what happens when you start your pc with both monitors connected?

Yeah same thing, goes to the login screen and won't let me progress. The right hand screen flashes blue and then goes back to the login screen. Going to try reinstalling my GFX card drivers :S

it seems more like an os problem, could be something of a bug in 8.1 preview.

there are official 8.1 drivers out now, also grab driver fusion and run the nvidia driver cleaner after removing the current ones and not restarting then run driver fusion and restart.

Ah yes, I considered that too, very strange though considering there's very few issues with dual monitors for other people. Thanks for the help, going to try these two monitors connected to a friend's PC as well.

edit@ thanks i'll try that too

I just installed a 4th screen above my 3x eyefinity setup and had similar issues with 8.1. My gfx cards are AMD so its probably an OS glitch rather than your nvidia drivers. I couldn't get past the user log in screen, I'd enter my PW and all 4 would just go black. I don't really have much advice for a solution, I attempted to log in several times and then would hard reset. All 4 eventually made it to the desktop/metro after the 4th or 5th hard reset.

8.1 has been really glitchy for me. The mouse issues are driving me nuts.

In case anyone else has this, the answer is found in the latest beta drivers on guru 3d. (Guessing I can't provide a link here)

They have this:

Supports DisplayPort 1.2 for GeForce GTX 600 series GPUs.

Guessing that was it. Awesome, thanks for the replies mauller07 and bjaminnyc,

I know this says solved already but I just had this problem yesterday. After checking connections, updating drivers and looking online for an answer, I finally broke down and called tech support. After a few hours we figured out that Windows 8.1 was not supporting the analog cable I had the second monitor hooked up with. If you are struggling with this like I was, save yourself a couple hours and try a direct DVI connection. Between that and updated drivers it's working just fine now.
