graphics cardmotherboardvideo
I got this emachines ET1331G-03W with a built in integrated video card (GeForce 6150SE). I added another video card (e-GeForece 6200 LE) in the hopes that I utilize both and have a dual monitor. But once the additional card was installed, windows 7 does not recognize the integrated video.
Is it possible to use both video cards and have a dual monitor setup? Is there a switch on the motherboard that I have to turn on or off to enable the integrated video card along with the new card.
Thanks!
Many cards offer 3 display ports, but most can only drive 2 displays at a time.
I would like to expand to 3 monitors.
For this, you'll want a ATI Radeon HD 5xxx.
Drive three displays simultaneously with independent resolutions, refresh rates, color controls, and video overlays.
The ATI Radeon HD 5670 would be the entry level card, price around $100.
The ATI Radeon HD 5750 costs around $135.
All ATI Radeon HD 5xxx support Eyefinity multi-display technology:
It's and either/or situation. You typically can't use dual monitors across integrated graphics AND a graphics card. This is because the BIOS recognises the graphics card selects it as the device to display the screen. This is so the CPU (which renders the integrated graphics) can be left to do what it does best and the GPU then does what it does best.
This is a feature of the motherboard and can't be switched off as far as I know. If you want dual monitor support...
Update: While SOME mobo's can enable integrated graphics with an external graphics card (e.g. https://communities.intel.com/thread/42192) but from my research, the mobo has to be able to set the integrated graphics as the default. Unfortunately, your particular model doesn't enable integrated graphics as the default, only as a fall back. So what I said still stands.

You will have to go into the BIOS to find out. Check your system documentation to determine how to enter the BIOS at boot-up. From my experience, most BIOSes disable onboard video by default when you install a video card.
