Surround it with art. All the blacks in the art help to make the black screen not stick out so much.
Off-set the T.V. on the fireplace wall with another beautiful piece of art work/accessories. The T.V. is there -with no shame, just placed with other more interesting decorations that draw the attention.
Place the T.V. in a bookcase next to the fireplace.
Hang dark wallpaper behind the T.V. to camouflage it.
In a kitchen space, this website suggests treating a T.V. as an appliance among many on a wall, it becomes invisible in a way.
Keep the T.V. small in a kitchen space, and place near a corner. Not to mention, the gorgeous tiled wall (likely not so inexpensive:) behind it overshadows the small T.V.
This one takes some handy-work. The art pieces are mounted on tracks and slide to the left and right to reveal the T.V. Cool, huh? (Off the subject - look at that awesome chair that looks like its made out of a radiator)
So, what do think about displaying a T.V.? Do you care about disguising it? Do you have any other cool ideas for down-playing a T.V. in a room?
