One morning as we were eating breakfast, Lindy (my wife) looked over to the other room where we had a TV sitting on a sofa table and commented that it looked "terrible" because of all the wires all over the place. This is basically license to knock down the entire wall and do whatever you like as long as she can't see those wires when you're done. I stopped short of that and just pulled a little part of the wall off.
As I see it - to hide the wires we'll need to put an outlet down by the lower shelf there, one behind the TV, and add low voltage boxes for the signal wires to go through. On the left there's a network cable running along the floor to the router (dunno why, I always hard-wire media devices). That's an easy one since it's one of those fancy new flat cables. I'll just tuck it under the baseboard. Here's the before photo:
Then I removed the drywall and found this. Note - there's a backing board in there (1/2" osb strip) - it's there to support the drywall joint... they didn't meet on a stud so they thought that'd be an awesome idea:
And then I installed the two outlets I needed and the low voltage boxes. Here the ones that will be behind the TV have plates on them already (not sure why, apparently I thought that was a good idea at the time):
Was all that shenanigans worth it? Yep. Looks pretty awesome. And Lindy's happy, so I get to point at the floating TV for a few months to justify my position in the relationship 😉
