No, the size of the display doesn't matter at all. The only thing that matters is how many pixels you're trying to drive. 30" computer monitors require dual video cards, because they are running resolutions like 2560x1600.

When you are driving a HDTV, the resolution is going to cap out at 1080 vertical, and usually 1920w. So an actual 30" computer monitor will be driving over four million pixels (and thus require two gpu's) while a flatscreen TV is only going to be pushing just over two million pixels. (Multiply HxW, just like finding area)

When you are using a flatscreen TV for your computer monitor, it needs to be far away from you. At least four feet. Do NOT use a TV as your display up close if you value your eyesight.

And the best cable option is DVI, the computer (4+ year old) monitor display standard, which many TV's will accept. This should let the computer auto detect your resolution.
