I had my tv mounted on the wall really sturdy, and had acoustic panels to the sides. I always pull my speakers out far from the walls. Having it set up like this wasn't bad but no tv is the best.
If you are doing a tv then mount it on the wall and figure out a way to block it with a few acoustic panels.
I take my tv in and out of my rig but everytime I put it back in I wonder why... I'd rather be listening to music on my stereo than watching some crap movie.
