I agree, leave it empty. It gives the room breathing space and allows the art you already have in there to show well.

Select some more striking wall decor to use around the TV

yes, I don’t want it cluttered. Do you think I should move the pictures a little further away from the tv?

I think it looks good “as is“ - I wouldn’t move anything or add anything. The blank area allows the eyes to rest, and helps define the rooms (dining room to living room)

You have so much around the tv, the tv is now the focal point. Less is more, and yes move the prints over

Thanks For the great input.
