 Well, give yourself a gold star because you're right. Hanging a big old TV on a blank wall creates a big old focal point of black nothing. So compliment that by using black and white art and accessories around the television. Silhouette art is perfect for this. Use black frames, white mats, you get the picture. The black of the images will draw the eye away from the black screen. Another way to make the screen better looking is to freeze frame on a nice shot. Say maybe a guy with a bullhorn building houses. Hmm, and I wonder where you could find someone like that.
