We'll show you how to tweak your TV's color, brightness, picture mode and more. It'll make a huge difference.

• A place to start is switching to the mode called Cinema, Movie, Calibrated or Filmmaker. These will dial back some of the picture's more garish aspects.

• So it may seem counterintuitive, but you should turn the sharpness control down, way down. Some TVs look best with the control at 0. Others look best within the first 10% or so of this control's range.
