Shoma, your processor is your CPU. INSIDE the computer, socketed to the motherboard. Please for the love of god learn proper terminology, you're confusing us all. HDMI and DVI are compatible for video, but HDMI also carries audio. If you don't have a DVI socket on your motherboard (Onboard video) or your video card, you don't have DVI. You'll need to buy a newer video card that does have it if you want to use it. You CAN however hook up with a VGA cable, if your plans are to hook up to an HDTV, if said TV has VGA in. And you will be able to feed the TV HD signals (To 1080i)
