Thanks for suggestions!

You need a larger more traditional TV stand such as this  https://www.lockstockandbarrel-uk.com/widescreen-mahogany-tv-cabinet-cbn055/

You can improve this room quite a lot without changing the furniture. I would move the small table away from the fireplace and centre it in front of the sofa, remove the lace runner, and place a bright bouquet on it instead.

Above the sofa, I would replace the small picture with one larger colourful artwork. Then I would pick two or three colours from that artwork and repeat them in decorative cushions on the sofa. I would also reduce the number of small frames on the mantel and keep only a few favourites so the fireplace looks less cluttered.

I used a similar approach in the $2,000 version of this living-room comparison — adding colour and character with affordable artwork, cushions and carefully chosen details rather than replacing everything. The links to the artwork and colourful decorative cushions are also in the video description:
