Windows 7: 2nd monitor added but goes black after a few seconds..

04 Nov 2010   #11

Win 7 Ultimate x64

I swapped cables, same thing. I swapped ports, same thing. The only refresh rates are 59 and 60 Mhz..I tried all combinations.
I added my wives monitor to the 2nd port on my GPU, and it worked fine.
Perhaps the monitor isn't win7 compatible ? I couldn't find any drivers newer then Win XP..

Windows 7 Ultimate 64 bit

Try hooking up the monitor in question up to onther system (say a freinds) and see if it works....I leaning towards the monitor itself is defaulty in some way. If you hook it up to another system and it works ( on a system w/XP and one w/7). Then there is an underlying problem on your system.

Win 7 Ultimate
It's a bios thing

I have a system that's been running fine for years. I had the motherboard replaced (god bless the seven year HP warranty) and now when I plug in monitor number 2 they both go dark. The tech said something about maybe needing to do that before he left, and at the time both monitors worked fine, but now when I plug in both, both go dark. So I'm guessing he was right. Anyway, I'll keep you posted.

Win 7 Ultimate

I went into the bios and enabled monitor tracking. That seemed to fix it!
