Can you remove the brick hearth. Then you can add a console on the floor that's almost the full length of the wall to hide cords.

what you really need is a console to fit the size of that wall and the tv. what you currently have is far too small. (and, if you can mount the tv to the wall, even better)

Any of these options would look way better

and, what is with that brick hearth? is there a fireplace there or what?

The entertainment center is way to small. I think until you fix this it will never look right..Plus it will help hid the cords. Some great examples have been posted. I am a bit confused on what is on the floor in front of your console.

I'm in a rental and can't mount my t.v. I opt to put a entertainment center on top of the fireplace. The fireplace doesn't work. There isn't anywhere else to put it without the seating being off 🤦🏾‍♀️

then get a longer, taller unit that spans about 2/3rds of that wall. if you get something with legs, it should be enough to sit over the brick ok.

check 'credenzas' or media cabinets on wayfair

then do some pictures around it
