Windows 7: Dual Monitors

06 Dec 2009   #1

Windows 7 Ultimate
Dual Monitors

Hello everyone!

Here is my problem. I am running Windows 7 Ultimate Edition on my desktop PC. I installed a fairly old graphics card (dont need anything fancy for software programming). It is a Jaton 117PCI with 32MB memory. Also I have a ATI Radeon HD Pro 2600 Installed. I cahnged my BIOS to boot PCI first instead of PCIe. Windows will boot up but no display on the ATI Card. I go to device manger and it shows both cards, with no conflicts and working properly.

When i access the displays menu in Windows 7 it will only show my montior on the Jaton card and will not show my ATI card as being active.

Is there anything i can do to get these two cards to work together? (I thought i was really good at computers, but now haha this has thrown me for a loop)

I found this post:
Triple Screen troubles
it was identical to my problem except my setup was different, his method of fixing his problem i dont think is going to work for me.

Also, the ATI card has two DVI ports and a S-Video, i just dont have another monitor with DVI. When i use a DVI to VGA converter the monitor wont come on it will stay in power save mode. I know the ports on the card are working because I can remove the converter and plug it up to my other monitor that has DVI on it and it will power up.

So any help to solve either one of these problems will be greatly appreciated. If there is anymore information you may need please let me know!

Thanks, Jonathan.

P.S. Sorry for making another thread concidering I found one already that was close to my problem, I just couldnt find exactly what I was looking for.

When you right click on the desktop and select Resolutions do you get the option for both cards there?

If you dont, have a look in Device manager and see if they are both WDDM 1.1 Cards because i believe they have to be to run together.

If you do, try installing the actual drivers for your monitors, as that fixed similar problems mentioned at the end of my original thread...

Thanks for your reply. I installed all monitor drivers... unfortunately it didnt work. When i boot the PCI slot first both card show up in device manager and show to be operating perfectly. But when i boot to the PCIe first the old card in the PCI Slot (Jaton) shows up with a error in device manager. Error code 10 Device cannot start. I downloaded the updated drivers for that card and it still wont start. However, how do i tell if the cards are WDDM 1.1? i looked through every spec on the details tab and it shows nothing of that sort on either of the two cards.

Thanks again!

You can't use both cards in the same system under Windows 7. That 32 mb card will never have Aero, even if it was the only card in the system. So remove it from the system.

Install the monitor driver for the second monitor while attached to the ATI card.

Use safe mode and the device manager if necessary.

I have a DVI to VGA Converter. The Output on the Adapter is DVI and the only input on the monitor is VGA. Will this work? Ive read somewhere that it probably wouldnt work due to the fact that it cant convert a digital signal to a analog one.

However with this converter in place, the pc detects the monitor and displays the correct model number and manufacturer, however the monitor stays in a suspended state. (Power save mode) ive tried different resolutions and refresh rates, still nothing.

Is there anyway to get this monitor to work with the DVi-VGA Converter? The monitor is a Dell E151FP Flat Panel, its fairly old too, manufactured in 2001.

(I removed the 32MB card from my PC as you suggested, you were right it wasnt worth the hassle for something so out of date)

Thanks again for yalls help!

(Has anyone figured out a way to enable onboard video with a graphics adapter installed?)

Most motherboards do not allow integrated vga with a card installed too. Some do though, so you can check in the bios for settings.

The adapter should work. See if Dell has a monitor driver for it.

Run the latest video card driver if you aren't already.
