The SRM-21.5 Series Sunlight Readable HD LCD monitors are designed to operate in direct bright sunlight, or in other high ambient-light conditions. These state-of-the-art monitors produce over 1,000/1,500 nits of brightness (vs. 250-300 nits for standard monitors). This results in amazingly bright, crystal-clear HD images, even with direct, bright sunlight on the face of the screen. The SRM-21.5 Series Sunlight Readable monitors are ideal for use in a wide range of industrial, law enforcement, aviation, marine, military, inspection, advertising and transportation applications where viewability in direct bright sunlight is crucial.
