What do you intend to keep? Is the cabinet built in or non negotiable?

I like a dark color on a wall behind a TV. It helps with the viewing. You have an exterior corner on the right, so ask the person installing the paneling how they intend to trim it. Do you have an image of the acoustic paneling you are considering? Is this wood paneling what you are talking about?

Hello heres a few im looking at i dont know which color

It's a small space, and crowded, Don't contrast anything on the TV wall.

If you need a light there, add a sconce rather than a lamp on the console.

For a cleaner look and to help with acoustics, extend the curtain rod beyond the window trim. (move it up as high on the wall as you can... even if you need to pull the console to the end of the wall).

Whatever color you choose, paint the console cabinet the same color.

yes, lower the TV

From what I can see? It's an element you are jamming into a space, that in all other regards does not suit what you want.

Show the rest? Someone may have a suggestion more suitable. Avoid the one from column A , one fro B, on from C approach......no matter the room you are designing.

There is no minimalism in the space now so maynbe try just eliminating stuff first to see if that is all you need. It is always a good idea to post pics of the whole space you are wotking with too.

I believe the ones you are looking at are all too busy. I would keep it more simple. Perhaps a low console and get rid of all the clutter and call it done. Or if you really want a panel of some kind one wood colour only

Everything on top of the cabinets will be gone i took photo of this during cleaning

I would change the cabinets below to be something for simple and seamless. All the different cupboards makes it look cluttered and is likely too high making you then want to put TV too high

Are those Besta units that you're using for your media console? I've seen some hacks that look really nice using Besta units.

Since you don't have a center speaker or sound bar on the top of the media console that is preventing you from lowering your tv, I'd still move the tv down a few inches.

If the media console is too deep for your room (hard to tell - but it looks like there isn't a lot of room between the console and where your seating is), you could always replace it with a less deep unit (and if it is Besta, maybe use the shorter units and float them on the wall). You can easily repurpose that media cabinet for some other use - people use Besta units for all types of storage needs.

Besta cabinet used for dining room:

Another way Besta units have been used to create built-in storage (split the media console into two units for each side of this built-in storage) with shelves installed above the units:

Besta units used for toy storage (changed doors to a lower drawer unit + two open shelves):

Of the three photos you posted of ones you're looking at, the third one fits the look of your space the best to me.

Or should i use a wallpaper?

Less is more and this room needs paring down. there is way way too much stuff on all the surfaces. also the fake plants should be donated or tossed.
