Windows 7: Motherboard video and video card in same PC

Motherboard video and video card in same PC

I'm running Windows 7 Ultimate. The HP I have has onboard video. I wanted to be able to add a video card and attach a cable to it for using my Vizio TV for DVD's. I connected a regular video cable from the TV and wanted to connect it to the video card. I had an old NVideo card that I installed and I installed it BUT when I rebooted the PC I got no video for the PC. What I was expecting was that I would be able to keep the video cable connected to the card and when I changed the input on the TV from computer to TV the TV monitor would kick in and I wouldn't have to keep bending over and unplugging the cable for the PC monitor and plugging in the TV cable. When I turned the PC on I got no video from the PC monitor. Any suggestions?

typically, when you add a video card, you must disable onboard video.

Actually not typically. However, in this case you are correct.

You need to make sure that the "primary" display adapter is the onboard one instead of the add in card... There should be no problem running both onboard and add in display adapter in tandem these days...

As was said above not typicaly reason why most motherboards when a gpu is installed it automaticly overrides the onboard but here and there some models you have to do it yourself

Most of the time when updating a video card you make sure it will support it and enough power to use it also drivers must be eliminated and some installed

the best way to know for sure is to consult you're owners manual mb and gpu

My idea was to be able to change the input on my TV to computer and my flatscreen TV will actually be the PC monitor to watch movies, etc. and still have the PC's regular monitor to use for whatever at the same time. Then when I was done I could just change the TV input back to TV and wouldn't have to switch cables out. In other words be able to use the TV for movies and still use the PC for whatever at the same time.

Then you just need to right click desktop, select screen resolution and from the "multiple display" drop-down select extend these displays then save.

Ahh, I see what you mean... It's easy then, set the onboard display adapter as primary, add in card as secondary, then in Windows (as RST101 said earlier) set your TV as a secondary display (extend desktop to this display) and be done with it.

The down side, if you switch to TV, and your TV doesn't send HDMI off signal to your PC, on the PC side, your desktop will still shows as extended to 2 monitors (1 your real PC monitor, the other one is the TV).

One thing that would help is this,

or failing that the full model number of the computer as well as the model of Nvidia card that was added.
