I would add an end table next to your seating, and just put a piece of art on the wall to the right of the tv. Post more photos of the whole room. Do you need a floor lamp or table lamp for the end table? A bookshelf might work on the wall under the window, but it depends on the rest of the space.

Not enough information about your room, how it is used, who uses it and what your style is to say much about a single corner photographed out of context.

If you can find a longer, more substantial TV console, you might not feel like the corner needs its own piece of furniture or decor.

snake plant in a tall planter. maybe a basket next to it to hold small clutter.

I had a snake plant there! But it started to droop, I may just replace with a fuller one because I miss having it there.

It’s just or TV/family room. Open to the kitchen.

a shorter fiddle leaf fig? A plant with more fullness than snake plant. Maybe some staggered thin shelves on wall to make family photo gallery & get those pics off the window sill. Room seems functional if a bit bare & sterile so I think the addition of greenery & something on the wall would add warmth. Hard to kill a snake plant & you have a window for light. If it was drooping from lack of care maybe think about a good quality fake plant. 😊

I think i over watered it. I’ve moved it to a new pot and hoping it perks up. Yea thinking a bigger plant maybe

Yes, too much water will make leaves mushy at base & outer leaves will fall over. You can cut the bent outer stalks off, let the ends dry & stick dried cut end into soil to root. New plant! But if snake plant gets too wide & tall, the outer stalks may also get creased at base & fall over too from the pressure of inner stalks pushing on outer & outer ones have nothing to support them. Same deal, cut off & start new plants. Just in case you were interested....nothing to do with your decor question!

I would do this. Additionally, paint that vent same color as wall. You want to draw attention away from vent and window. You also look like you could use more storage. So I added cabinet with drawers and I would buy baskets for storing miscellaneous items on TV stand. It will help control clutter and help keep things organized. I added a couple zebra striped pillows to sofa to repeat black frames on drawer unit.

Longer TV console eith drawers or doors to store stuff. Ikea has some that are not too tall and you can align two pieces to get the look you want. If the console extends a bit more toward the window, that is not Centered under the tv, you can add a plant on top.

Get a wider TV stand maybe Besta fro IKea and run that right acroos that whol wall

Closed-door/drawer cabinet furniture would help control the clutter. Move the giant black footstool away from the sofa or out of the house. Add some color (a couple of plants, art, two or three accessories, a couple of pillows). Don’t put anything on the high ledge over the tv if you ever have had an earthquake. Your children will grow up and you won’t need toys in the room forever.

Possibly a longer and more sophisticated TV cabinet.

jennamart snake plants are known to be really easy to care for. if it drooped in that corner, don't get a new one! maybe you don't have enough light for a plant there. in that case, I think the wider TV console suggested above will work to fill that space.

I would get a much longer tv cabinet - it should span much of the current wall - keep it low like the current one. Then, put a tall plant or vase or a piece of art in the corner on top of the cabinet (whatever you choose, have it extend higher than the tv to marry the tv, upper wall space, and window). Add a side table with a lamp near the end of the sofa.

Christmas tree?

I’m really liking the idea of a long TV cabinet. The current one is 66”, but the wall is 130”.

Not sure i can find a long enough cabinet. Maybe a custom build (a girl can dream!)

what about the longest cabinet you can find, and then put a floor lamp on either side.

something that's soft, on a dimmer, so it doesn't hurt your eyes while facing the TV (and you can turn it up brighter when people are not watching tv).
