Bisjac, pefu... The reason you guys haven't come to a resolution yet (huehue, a pun) is because you forgot one very important thing: pixel density. Monitors, in general, have higher pixel densities than TVs for several reasons. A couple are:
Nearly 100% of the time you will be at least 5/7 or more feet away from your TV (if you're using it as a TV). Not true for monitors.
On a computer, you're not having data streamed to it wirelessly most of the time. Untrue for TVs. Most of the time, using a TV involves streaming data from somewhere, and the less data downloaded, the faster it displays it on your screen. Thus, lower screen res.
There are many other reasons, but that's the basic difference; dpi.
