Computer to TV is blurry and cropped

I'm trying to hook my computer up to my TV a Samsung HC-R4245W which is an 1080i TV. I am using a HDMI from my computer to a DVI to the TV by way of a small plug converter. No matter what I try the screen is still blurry and cropped cutting off a chunk of the screen on each side. I've changed the picture mode, the screen resolution, sharpness, and checked on the zoom, but I can't adjust that. Even my PS3 has the same problems. Any ideas on how to fix it?
