The living room sofa is too far from the TV background wall. It's going to make a partition behind the sofa, but I don't know what to put in the empty place behind it
Love a flower or a goldfish, can put a long narrow flower bed, or narrow long goldfish. Like calligraphy and painting, the wall can hang calligraphy and painting, or hang large decorative oil painting. Be sure not to be full. Leave the aisle, so elegant and atmospheric. It is also convenient for cleaning.
The sofa is in the center, and no partition is needed behind the sofa so that it forms an aisle between the wall and the wall. You can arrange anything you like with the wall, for example, like antiques, furnishings, and a large decorative cabinet.
