Dual Monitors

By patb071 ·
I have an hp 6000pro desktop (windows 7). We are looking at running dual monitors. I have purchased an ATI Radeon HD 4650 Video Card
Thinking this supports dual vga, it has a dvi port and 2 display ports. the card also came with a dvi-vga converter and a display - dvi-d converter, and no one has a dvi-d to vga converter. Couple of questions 1st when i install the video card why isn't the built in video card showing in device manager? 2nd since my 6000 pro also has a built in display port can i get by without another video card, if i get a display port to vga converter?

I should think you can

If your built in graphics card has both vga and DisplayPort then there seems to be no reason why you couldn't run 2 x VGA displays from it with a DisplayPort to VGA adapter
The reason why your in built video card has "disappeared" from the device manager is likely to be because it gets disabled by the bios when you plug in a PCIe graphics card, removal of the ATI Radeon will restore functionality of the in build card I'm sure

Well as already stated when you plug in a PCI Express

Card the On Board Video gets disabled by the BIOS.

But according to the ATI Specifications of this card it has

Two independent display controllers
Drive two displays simultaneously with independent resolutions, refresh rates, color controls and video overlays for each display
Full 30-bit display processing
Programmable piecewise linear gamma correction, color correction, and color space conversion
Spatial/temporal dithering provides 30-bit color quality on 24-bit and 18-bit displays
High quality pre- and post-scaling engines, with underscan support for all display outputs
Content-adaptive de-flicker filtering for interlaced displays
Fast, glitch-free mode switching
Hardware cursor
Two integrated DVI display outputs
Primary supports 18-, 24-, and 30-bit digital displays at all resolutions up to 1920x1200 (single-link DVI) or 2560x1600 (dual-link DVI)2
decondary supports 18-, 24-, and 30-bit digital displays at all resolutions up to 1920x1200 (single-link DVI only)2
Each includes a dual-link HDCP encoder with on-chip key storage for high resolution playback of protected content3
Two integrated 400 MHz 30-bit RAMDACs
Each supports analog displays connected by VGA at all resolutions up to 2048x15362

So all that should be required here if the Card that you bought has 2 Video Outputs is to connect a suitable Monitor to each Output and then open the Catalyst Control Center and setup the Dual Display how you want it.

However depending on who made this particular Video Card it may not have made use of all of the available features of the ATI Chip Set so you'll need to read the manual that came with the Card.

As for the On Board Video if it has 2 Output Ports you could just as easily use this to give you a Dual Display though you may need to mess around a bit more to get it setup than what you would with the ATI Setup.
