We already asked about the size of your TV, so it is only fitting that we do a follow-up focusing on computer monitors. The choices after the break offer a basic range that should accommodate owners of most laptops, LCDs and CRTs. Just pick the number that is closest to the measurement of your viewable area (rounding up if necessary). That having been said, if you own a CRT, keep in mind that the two types of monitors are measured differently. Make sure your figure does not include the screen frame. UPDATE: TV monitor option added.
