I have spent 7 days on this, please do help!

OS: windows 7 ultimate 64 bit

when i boot, I can see display on both monitors, only till after that small 'window' icon, then the monitor on DVI shows no input siganl. The monitor on VGA connection always work. I can see both monitors on NVIDIA control panel, I tried a lot on the control panel, but the 2nd monitor just won't work. The latest driver has been installed for NVIDIA graphic card.

So let me recap, both monitors work fine, and they both can display the booting info, but after entering Windows, the one on DVI lost input signal.

One interesting thing is, the monitor that works is identified as #2 monitor on Nvidia control panel.

Thanks in advance !

Have you tried rightclick desktop -> screen res -> detect. If it doesnt see the screen, are you sure your graphics card has it's AGP/PCI power connector connected (if you built it, or if it has one, in the right up corner of the card, a six or eight pin connector). If still no picture, try to press detect, take out one monitor, press detect, and put the monitor back, and press detect.

Assuming the monitor connected via DVI is a LCD, check the refresh rate and make sure it isn't set above 60 Hz.

Also what resolutions are you running on the monitors, and are they set in clone or extended mode?

Yes, it has power connector and it's connected. I tried "detect", and it is not working.
I set the refresh rate to 60, and change resolution from800x600 to 1024x768, bbut none of them works. it's a LCD。

this video card is killing me.

the monitor on the DVI connection if you are using the DVI cable try going into the setup menu of the monitor and select DVI input

you may also try using a VGA cable with a VGA to DVI adapter at the card

i just had the same trouble. you need analogue not digital output. So in the Nvidea control panel, go to set up multiple displays and select displays 2 and 3 , instead of 1 and 2. this will activate the vga and dvi outputs
