I would leave the TV where it is; it is at the appropriate height for viewing. I would paint that wall to match the others in the room. It would diminish the contrast between the TV and wall. I would place minimal if any artwork around the TV. You are going to run into problems placing your pieces around the various switches. I don't see any lamps in your room. I would focus on lighting and window treatments next. I love your area rug - I would find some way to use that beautiful shade of blue as an accent color. And your pup is adorable!

I would do a wall unit in the center section and put the TV within that. And then I would get two matching pieces of furniture for the two side sections, some type of console or buffet type piece. I would wallpaper the three niches to give them some texture, and then hang your art work on top of that in the two outer sections

I agree that by itself the map is a bit muted but if you love the map idea, you could just add more in different colors, some brighter, etc for a gallery wall of maps. if you just want one large piece of art, it needs to be much larger for that wall, length should be 75% of the length of the sofa.

Thanks everyone! i like the idea of the series of framed prints and may go that route! I know the tv over the fireplace isnt ideal but that is where is was before we got here and unfortunately there is no other place that we feel would be good for it (I dont like the idea of using the back wall and putting the couch back to the fireplace), we will be getting a mantel and a mount that you can pull the TV downward to eye level but havent gotten there yet!
