While watching television, the lighting in
the room should be dimmer than the screen. Make sure that the lighting
doesn't reflect on the screen or cause a glare. Don't watch in very dim
light because the contrast in light is almost as bad as glare. Avoid
viewing from an angle which causes an unclear or glare effect. Sit in
front of the plasma screen about four or five times the width of the TV
screen away. This is just a rough guide.
