In a viewing environment with a single direct-view display I recommend dividing the room lighting into a minimum of two independently dimmable lighting zones. One of the dimmable zones should be dedicated to the specific task of illuminating the wall behind your display. This form of lighting is referred to by some as “bias lighting.”
Though wall sconces are popular with many custom home theater owners and designers I recommend avoiding them if they’re not designed solely for indirect illumination. Ideally all illumination in an optimal viewing environment or home theater should be indirect and diffuse, especially the lighting used to illuminate the wall behind your TV screen. The bias lighting, which is very low level illuminance, is the only lighting that should be on during television viewing - all remaining lighting should be off.
For additional information please read my response to the following Yahoo! Answers question:
Where should light source be placed/located in the living room relative to the TV?

I am a very strong advocate of dimmable RGB LED lighting systems that are capable of full additive color mixing. This new solid-state lighting technology will allow you to easily produce white light with an optimum correlated color temperature (CCT) of approximately 6500 Kelvin while also providing a high color rendering index (CRI) of approximately 94 or higher. Solid-state lighting also offers other important advantages over other forms of lighting, i.e., it generates no UV radiation, produces a negligible amount of heat, and uses a minimum of electrical power. No other lighting solution currently offers this highly advantageous combination.
Another worthwhile lighting technology is light pipes or optical fiber systems. For more information I’ve posted additional resources below.
If neither of these lighting technologies is readily available or of little interest to you then your only other remaining option is to install specialty 6500 K (‘D65,’) high CRI, dimmable fluorescent lighting. Keep in mind that the colorimetric requirements for any room lighting that should be off during television viewing will not be as critical as is the case for lighting used to illuminate the wall behind your TV.
