Mick to add to what Tim said at the top.
Some years back our IT guys started looking at cheaper large screen text resolution for our nurse station walls (hospital).
720p didn't cut it.
1080p res is more crisp and legible with fine text if you are thinking TV with hdmi input.
1920x1080 = 1080p
(Had to edit, the late night cobwebs were effecting me when I first chimed in.)
