I just moved and am setting up my new project studio for audio. I am in need of a new monitor for my setup, but am thinking of saving some space and getting an LCD TV that I could use as both my monitor and TV. My budget is $500 and under. Would it be wise to try and set up my monitor for both my computer and cable box? I don't do much photo editing or anything where I need a killer display. Anyone have any advice? Thanks!
