i have finally created enough shortcuts (and got use to using them) between the computer keyboard, mackie contorol, and an evolution mk461 midi controller with 12 knobs and 8 faders and a couple pieces of good ol analog that once I've done my edits the main screen goes off. I leave a smaller 15" monitor on, but placed to the side and usually only will display active plug-ins. Lighting is crucial to me. I've got to have it bright as possible when I'm doing edits and working the beginning of the mix, as I get closer to the end of the mix, the lights start going off a little at a time. By the end, maybe just a candle or 2 with a little light for the rack and controllers. My mixing has gone from completely amateur to "in the ball park" real quick since I've started this.
When I'm getting real close to hitting that magical point where the mix is where it wants to be, out go all the lights, I move from my chair to the couch near the back wall close my eyes and listen all the way through. If I don't hear anything to fix, I'll switch my monitoring from the nearfield/sub combo to a consumer onkyo reciever powering some old ass yamaha NSA180's and do it again. Eyes are always closed, lights are always off.
