yes, you could
hook it to your TV... but why would
The monitor is progressive scan (like HD tv is) high-res while your 27" tv is interlaced low-res picture. You can also change the res on your monitor and on the TV you can't. Running your TV would be roughly the equivalent of running a game at 640x480 and then displaying only half
of the display info at one time.
Even a 17" monitor, lcd or crt, will look better (especially close up) than any
analog TV... and most HD tvs.
