you can build a picture frame around it.

I am doing that with my 65" flat screen TV. I'm doing a painted frame that coordinates with my molding, panels, and chair rail and I'm painting to match my walls and moldings. I'm doing a reverse stepped picture frame since the TV protrudes three inches from the wall when mounted on the articulating arm. the picture frame is mounted on the wall and the TV can be pulled away and angled to meet my needs.

if your TV protrudes an inch or so, your picture frame could be similar to a regular picture frame and not have a reverse stepped frame. you can attach it to the wall as well. if you want to spend the money, you might go for some wood that can be stained. the picture frame style really depends on what you like and your budget.

there are companies that make these frames just search the Internet for "Flat Screen TV Picture Frame".

You could try incorporating the tv into a gallery wall (as if it were one of the photos). I think this looks especially good when done with black and white photos.
