With a 3 monitor setup on your PC, it is quite easy to start having too many screens. What was needed was to have the option to have a TV when needed and be able to easily hide it from view when not in use. Some scrap plywood and two drawer slides are all that was needed.
I screwed a small piece of scrap to the back of my 22 inch TV and a attached the two drawer slides. I then took the other haves of the slides and mounted them to a piece of scrap that attached to the wall. After that, I slid the two pieces together and it gave me a sliding tv mount. I could slide the TV behind one of my 23 inch monitors out of view until it's needed.
