Please post more photos of the space. There is no reason for the t v to be in front of the slider. Yikes! What floor are you on? View looks great so I would suggest that area be unencumbered.

Yes the tv will go where the wall is (currently sofa)

just struggeling to find a nice matching rug, coffee table and tv stand. the floors are very very light grey

Frame the slider with drapes; put t v on that solid wall, with sofa facing t v. You probably will have some wiggle room for at least one more chair, possibly two,on either side of the t v wall.

A rug will ground the area.

Thank you. i am striggeling with the colors i should choose

The floating sofa, facing the new t v wall, try pulling it back into the area where the watch art is. Leave the slider and view unobstructed.

Thats where the dining room goes

So, my suggestions are null and void, because you haven't added more photos of the space, as I asked. Do you see the waste of my time trying to help you? You have no mention of a dining room...there is a room?

This is a picture facing the wall where th tv gies

All colors go with white. Choose colors you like.

Choose a rug that looks good with your wall art.

You definitely should re-think your furniture arrangement, the tv is not in a good spot, You have a good start, you just need to add some finishing touches.

If we could see the balance of the room, we'd have better suggestions, but perhaps the TV should be placed on this wall next to the sliding doors.

I woll try to get more pictures. where you ahve placed the tv will be the dining room

This looks like an apartment in a high rise building. Often their floor plans with measurements are online. Can you find and upload your floor plan?

It would definitely help to have a floor plan for your open layout. As for colour suggestions for your decor, there is nothing in your idea book so do you like any colour(s) in particular? do you like soft of bold colours? In the meantime until you give us a floor plan, maybe a layout like this can work in your room.

With a white sofa you actually have a lot of freedom, so I’d choose the overall mood first and then pick the rug, lighting and coffee table around that. Those three things can completely change the character of the room without replacing the sofa.

I recently transformed the same living room in four completely different ways — it might help you visualize a few different directions before you start buying pieces:
