I just need some clarification on running a cat 6 cable to behind my TV. The run is about 50 feet in total and I was just think about buying a 75ft premade monoprice patch cable like this, cutting off the ends and making a wall jack using a CAT6 keystone jack like this. I've been reading online but I can't really find any clarification whether this is possible or not so, if someone could shine some light on this that would be great!
Patch cables are normally stranded wire, not solid. You'll have a hard time getting stranded wire to punch on the keystones. You'd be better off buying a 50-100' small spool of cat5e / cat6 at Home Depot or other local hardware store...
I ran cat 6 throughout my entire house in this fashion. Quick, easy, and it works. I've got over 500' of these cables and a dozen or so of these couplers from monoprice. Make sure to test all your cables and these couplers first, just in case, although I had no issues.
Also, if you're as picky as me and want that decora look to match your outlets and switches, monoprice only sells the keystone wallplates as a whole plate. Leviton has the decora keystone inserts for 1, 2, 3, 4, or 6 keystones, and then you just use a standard trim ring and you can get those at Home Depot... couldn't find it on their site, but here's what I'm talking about:
