Are there any setups where I can run TV through my computer to display on my monitor and use the computer sound but also lets me have a remote control? Will this also let a Playstation, Xbox, etc. be run to play on the monitor? Also, If i get a monitor with high enough resolution, can it run HDTV stuff? either 720 or 1080 stuff? Thinking of a big dell or apple monitor for my computer and just not get a TV for my bedroom.
