An easy way to boost contrast and ease eyestrain

If you want to improve the contrast of your TV without ponying up for a brand-new set, bias lighting makes for an easy and relatively inexpensive way to do it. Bias, in this context, means that light is projected at an angle to your TV; more specifically, onto the back of your TV or onto the wall behind it, so that it casts a dim halo around the display. Once installed, a bias light can boost the apparent contrast of your TV, making blacks and dark areas of the picture look deeper than they did before. Bias lighting can also help ease the strain of looking at a bright TV screen in a darkened room.
