So I’ve had someone give me a 22 inch HD (720p) LCD TV. Is this something that would have the same quality as a 22 inch LCD monitor, or is there some other difference besides the tuner? I’m trying to figure out if this is worth using, or whether I should sell it and buy a straight LCD monitor? It has HDMI/DVI inputs, as well as all the other connections you’d expect in such a device (component, etc).

The main difference would be resolution. If the TV is 720p, that means it is 1280x720 pixels. That's not very much, less than even the most basic MacBook. A 22-inch LCD computer monitor is usually 1680 x 1050 -- almost twice the number of pixels when you do the math.
On the other hand, the TV is a TV -- it probably has a tuner and you can hook up cable or a DVD player to it. Video game consoles too.
