Nothing over the TV and a long narrow watercolour behind the lamp.
I would do a wall length low cabinet in a light color. The TV and the present cabinet create two blobs of black.

thank you. Any chance I can have two narrow photo canvases one above another behind the lamp? This is the only wall in the room where I can display family pictures. This wall facing a wall of windows with a fire place in between and a painting above the fire place. Adding a long watercolor will clash with the paining.

Too high up.

Not the place to display family photos. Don't you have a hallway where the idea of two long photo frames could go? That would be best. I don't think they would work well on the TV wall at all.

So, my only option is a mirror behind the lamp? This wall needs something.

what color is the paint on the wall?

Sherwin Williams alpaca (some shade of grey)

You could put a large piece of art. Small pieces is what to avoid. Something large, like a big mirror that leans against the wall or a oversize piece of art. Or a large wood carving. Has to be large and interesting. You could put a interesting bookcase there as long as it is tall enough. Should be taller than the top of the TV.

I don't know the style of your furniture, but this type of item could work. You could display a few favorite family photos on this type of unit. This is $$$$ but just trying to give you some options to consider.

thank you! this is helpful!

No photos. Just keep the TV. I think the photos would be to busy which could distract your view of the TV.

I have my TV surrounded by movies, books and family photos. I manage to concentrate on the TV when I need to.

If this is a private family room and you want your photos in this room, it makes sense to put them there.

If this is your main living room where you have guests, perhaps there is a better place for the pictures.

I'm like you. I want my pictures around me.

This is similar to my TV room (way better designed, but similar.)

Other examples.

I bet there is a better wall for them in this room. Can we see the options?

I think the art/photos will compete with the TV. You may want to instead consider TVCoverUps, art or framed mirror adds to the room's decor- with the hidden TV beneath. Motorized or Manual lift options.

See how EASY it really is :

Art should not clash if you pick something right.
I am not a lover of family pictures anywhere except maybe bedroom or office.( I have some in my walk in closet) but you could do two of the same size,same frame , lengthwise.
Another thing that could be effective is to wall paper that whole wall. Something that stands out and needs no other adornments. on the wall.
