I vote shelves- but another idea is to do black and white photo array. This would be fun and contemporary and adding a conversation piece to the room. Use photos you have or you can find some great ones at Homegoods or Aaron brothers.

its easy to call for ideas but suggestions come with a cost. not sure how much budget u have . still chose something sleak and long. legs and without a high wings or back panel. try a video channel on youtube. its claptrap , they have options

Hey Aly, One surefire and easy thing to do - a gallery wall. You could intersperse this with shelves and perhaps a couple of wall light fixtures! The rest of the ideas are already given to you! Wallpaper, Painted wall or full wall custom built TV unit. We hope this helps! Best, CUBSpaces Team

1st option Use the same rosewood/mdf on the TV modular wall to continue woodwork pattern as per the opp wall and add some storage as well. 2nd option make it a black TV cabinet with led strips behind. Change to light colored 3+2+1 sofas and consider using 2 Fancy Ceiling Fans with LED lights as the room looks dark.
