I posted pages back, but I use the 55B6 as a computer monitor. Honestly, in my opinion it is really less than ideal. How do you plan on setting it up? For use on desk or from your couch? I've got mine set on a desk. Sit about 3-4 feet away. 55 inches is really just too big for use outside of games. Scaling using windows @100,150,200,250% does not work well at this size. So I've set my scaling at 100%. Had to use this program,

Immersion is on another level for games though. After having this setup for close to a month, I feel like a 40-42 inch would be the ideal size for a desktop monitor, striking the perfect balance of function and immersion. EDIT: It's pretty insane to open an excel sheet at 100% scaling as one window... the number of cells is mind-blowing
