I am looking into getting an external display to run with my macbook. It would become my main screen in a sense, but i also plan on getting EyeTV. I am going to mount the display on an arm so that it will be easily movable, and im not sure whether i should get a 20" tv, or a 20" display. I realize that the tv wouldnt look as good for computer purposes, but the display also wouldnt look as good for tv purposes. It looks likei am trying to spend less than $300. Should i go with a tv, or display?
