I recently purchase a new computer. THe computer I purchased has a 19 LCD and the hp did not put a dvi connection on the computer, obviously i have it on the lcd. My question is if I buy a vga to dvi converter/adapter ($10) will the adapter transmit the image is digital or as analog. Or should I just buy a video card with dvi connection ($50-$200)?

by why me worry?

I have an ATI All in Wonder video adapter with a native DVI output, but since my LCD is an analog VGA, I have to use an adapter which was provided with the video card. It works just fine converting from a digital output to an analogue display, but I dounbt it will work the other way around since you are trying to convert analogue to digital. Are you sure your LCD display isn't capable of an analogue video signal input? I doubt HP would sell you a machine that cannot interface with the LCD display if it's part of a complete system package.

It's converting the signal from digital to analog. As Why Me Worry says, you can't go the other way. If you want to hook up your monitor using the DVI interface, you should probably get another video card that supports it.

Yeah I figured I wouldn't be able to go from analog to digital. HP didn't send me an adapter, I had to use my vga cable. It's probably better that I stick with vga because I'm going to buy a kvm switch and the dvi switches are quite pricy. Thanks guys.

Why do you go around convertor which will add more noise. Instead add a graphics card from nvidia or radeon or ATI with DVI output and connect your monitor to this DVI output. By doing this the full path is digital.
