I can use NVIDIA Quadro NVS 280 PCI video card to display dual moniors at HP DC7700 SFF computer in Window 7. But this video card driver can't list 1920x1080 resolution at "List All Modes". I do look at the driver's .inf file includes 1920x1080 mode. Don't know why it do not list it ? So I can't display 1080p widescreen. Any body has experience to modify the driver to show 1080p display?

This card is only 32bit therefore incompatible with Windows 7. This is stated on the manufacturers website. The driver that is driving your card will be a Microsoft generic driver which gives you the limitations you are having with it.
I am ahving the same trouble with a Dell 190L which has only 3 PCI slots and n0 AGP or PCI-E.
If you can get a 64bit card you may have a chance. That is my intention at the moment. Good luck my friend. I hope I have saved you some time. Cheers, Ray

I have solved the problem. Now I can display 3 monitors (even 4) using one NVS 280 PCI and one NVS 280 PCI-E video cards with my DC7700 SFF upgraded to Window 7 32-bit.
Normally PCI-E video card will stop the mobo integreted video, PCI card will not. But PCI-E card could work together with PCI card depending on machine. For my DC 7700 SFF, they can. Look at the HP link:
NVS 280 video card Window 7 driver 96.85 can be downloaded from Window Vista NVS 280 32/64-bit (Window 7 driver compatible with Vista), from link:
According to Nvidia for this video driver release:
This driver sometimes flashing when you click something. As I observation, if you load too large video signal, eg. opening many browers, it will. That's why I use two NVS 280 cards instead of using one NVS 280 PCI card and mobo VGA for three monitors.
For display 1920x1080p, you can read the driver's "mode" file, it does include 1080p mode. If ->Screen Resolution -> Adapter -> "List All Modes" doesn't show 1920x1080. Go to Monitor tag, uncheck "Hide modes that this monitor cannot display". Then go back to Adapter tag "List All Modes", you can see 1920x1080 mode.
For Microsoft generic driver, update driver, manually choose "NVIDIA Quadro NVS 55/280 PCI" or NVIDIA Quadro PCI-E Series" driver. You'll get it.

That works for you as you changed the card. Great stuff. My problem is that the Dell 170L has only 3 expansion slots and they are all just PCI, NO PCI-E or AGP slots on this board. My only choice is PCI. Cheers and I hope the new year is without stress LOL

My HP DC7700 SFF has 2 PCI slots, 1 PCI-E x16 and 1 PCI-e x1 slots. So I can use one PCI card and one PCI-E x16 card. For your all PCI slots, probably you can use 2 PCI cards to display 5 monitors as long as your video load is not that heavy since NVS 280 has only 64 MB mem.
Another consideration for me to use NVS 280 video cards instead of NVIDIA Geforce 6200, 8400, .... is NVS 280 has less power consumption (< 20W), and my HP DC 7700 SFF PCI/-E slots has only 25W each.
