Seriously - do you own or rent?
There's no reason to run wire UP a wall! Just buy a stud sensor and cut a hole in your wall and use a bullnose cover to make a clean entry into and out of the wall. Into the wall from your equipment location, out of the wall behind the display.
Surface mount raceway is pretty clean, as is tucking the wire behind the carpet and baseboards. But, if you own and are staying, then seriously considering making the hard to run pathways by opening some walls, spackling, and repainting is well worth it for wiring which will be in place for the next 30 years.
