Enabling Multiple Displays on GeForce 9500 GT
I installed an Nvidia 9500 GT graphics card with DVI, HDMI and S-video connectors in an HP p6240f with onboard graphics running Windows 7 Home Premium x64 upgraded to Ultimate. I installed the card in the x16 slot and changed the bios setup to use the PCIe x16 slot for graphics (three choices in the bios- onboard, x1 and x16.) I can't get dual display output on my LCD monitor (DVI) and my Panasonic TV (HDMI.) Trying to set up multiple displays in the Nvidia Control panel yields the error message "This GPU supports one display. To use two displays, reboot your computer." Rebooting doesn't change anything. I am guessing that this particular card doesn't support two displays since I've installed the latest x 64 drivers (196.75). I would like to ask if anyone has a fix for this problem before I give up and go out and buy an ATI graphics card (probably the HD 5670).

That card should definitely support two monitors. Have you tried playing with the windows display settings instead?

Hi. I've tried changing the windows display settings and find that the card detects the two displays (LCD and Panasonic Plasma) but even when I make the Panasonic my main display, the desktop just appears on the LCD. Extending the display and cloning the display are disabled with the error message "This GPU supports one display. To use two displays on the GPU reboot your computer." That might be a hint at a wrong bios setting but I don't know what else I can do besides enabling the PCIe x16 slot.
I have a 9500 GS running in another machine and it supports both the LDC and the TV at the same time under Windows Vista Ultimate. I've looked up different 9500 GT card specs and most of the cards seem to have dual DVI outputs. Mine has the DVI, HDMI and S-videa outputs. I'm wondering whether it is my card that's the problem or if it's the Windows 7 drivers. I found some similar complaints about Nvidia cards not supporting two displays under Windows 7 (but no solutions) on the Nvidia forum.

Update:
At the computer store today I looked at a lot of the graphic card boxes and found on some of them the mention that they needed to be supported by the motherboard chipset. I've found the specs of my motherboard at HP http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01746799&cc=us&lc=en&dlc=en&product=4006089 but there is no mention of whether the chipset supports using dual displays on the card in the PCIe x16 slot. I bought an ATI HD 5670 to replace the 9500 GT but am hesitating to open the box and install it in my computer until I figure out whether the computer motherboard might be the problem regarsing the multiple displays. Any ideas will be appreciated.

The grapic card was the problem. It wouldn't support more than one display at a time. Put in an ATI HD 5670 and now have support for three displays simultaneously along with HD audio 5.1 through the HDMI. Funny - both cards were the same price!
