Specifically designed for use in long term digital signage applications, the MDT421S 42" slim-line display combines reliable engineering and manufacturing with a stylish design that's pleasing to the eye. Whether as standalone units, or connected together in huge, eye-catching "video wall" systems, the MDT421s can always be relied upon to deliver excellent visual performance.

Ideal for use in airports, shopping centres, public hotels, business foyers and anywhere else where digital signage is commonly used, the MDT421S comes equipped with a range of features for the best possible performance. The full HD 1080P native resolution, high brightness and contrast, as well as rapid response time allow the MDT421S to deliver bright, vivid high definition images that are free of ghosting. Colour accuracy has been given special attention, with features such as wide-range colour temperature control and six-axis colour adjustment giving the user full control over how image colours are portrayed on-screen.

Multiple screen saving functions such as Gamma control and Motion mode combined with the commercial grade LCD panel ensure the MDT421S can be run for extended periods of time without a problem. A scheduling function allows users to program up to seven different scheduled intervals by time, day of week and input port, as well as control display on/off times to help conserve power and further extend the panel life.

Multiple standard input and output connectors, including HDMI and DisplayPort, offer the user great flexibility when connecting devices to the display. The CAT-5 transmitter/receiver found with MDT521S display, which allows both video and control data signals to be transmitted over a single cable up to 150 metres in length, is an available option for the MDT421S.

With these and other features such as flexible orientation (Landscape and Portrait), front/rear ambient light sensors for automatic brightness control and optional speaker/stands, the MDT421s makes for the perfect digital signage display solution.
