Uniformity of a monitor is the ability to display a single color across the screen. In our black uniformity tests, we want to see how well the monitor displays a fully black screen when there's a white highlight in the middle.

A TV’s black uniformity refers to how evenly a TV can display black all across the screen. It’s important when watching dark scenes in a dark room. For this test, we take a photo of the TV while it displays a mostly black frame.
