I am confused. The websites say it is an edtv monitor, but that it can display in 720p and 1080i with a outside tuner i.e comcast hd box or whatever. SO isnt that a hdtv ready set? or is it both. I am looking at trading it for my 62 " MItsubishi dlp . JUst wanna make sure I am getting a tv that can broadcast real hdtv not edtv upscaled to hdtv. Any help would be greatly appreciated.
