How to disable graphics card?

I've got a "Sparkle GeForce 9400 GT Video Card - 1GB DDR2, DVI, VGA, PCI-Express 2.0" and also a "Asus M3N78 PRO Motherboard - Socket AM2+, Geforce 8300, ATX, HDMI, SATA, Gbit LAN, Hybrid SLI". So my motherboard has its own graphics processor which I usurped with a better graphics card. I've been using my computer hooked up to a 22" LCD TV via VGA, but now I'm curious what the difference is if I use an HDMI cable.

My motherboard has an HDMI out slot and so does my TV. But my Sparkle graphics card only has VGA and DVI outputs. Plugging in the HDMI cable to the motherboard yields no picture. Is there a way to switch the computer's output of the image to make it go through the motherboard's HDMI slot rather than the separate graphics card? Is there a way to do this besides getting an HDMI-DVI adapter or without taking out the whole graphics card?
 
You will have to change the setting in the bios. Make sure the HDMI is enabled instead of onboard graphics.

Never mind, it doesn't have onboard graphics, just make sure the HDMI is enabled in the bios.

Are you talking about trying Hybird SLI with your onboard and Video card?
 
I couldn't figure out how to enable HDMI in the BIOS.
And no, I'm not trying Hybrid SLI.

I actually just removed my graphics card completely from the computer and then used the HDMI slot on the motherboard to hook up the monitor. Oddly, it didn't work very well. When I set the monitor to the resolution I use with VGA, it looked much worse with the HDMI cable. I'm sure that has something to do with the motherboard's inferior graphics capabilities, but I expected the HDMI to make a very clear picture. Is this a wrong assumption?
 
Your onboard graphics card shouldn't be "inferior" assuming you're referring to basic desktop/2D applications. But, HDMI won't be any better than DVI seeing as they are one and the same. DVI is a direct conversion to HDMI and vise-versa. The only real difference is HDMI cables carry audio and DVI can carry an analog video signal.
