I have an lcd monitor that I want to use to watch tv. I know I can buy a video card with a tv tuner with hdtv support or, theoretically, I could get a hdtv tuner and a cable that's vga or dvi on one end and has hd inputs on the other end and then use the remote from the tuner to change channels (I think). Either way, will I be able get HD quality tv signal on my lcd? My monitor is a pc, lcd monitor, not a tv/monitor and not hdtv enabled. What can I do to get full quality hdtv on my lcd monitor? Thanks
