42" LED, Commercial-Grade Large-Screen Display w/ Integrated Tuner
The 42” NEC E423, an LED, commercial-grade display, is ideal for education, corporate and other digital signage applications. Compared to previous generation displays, this model’s edge-lit LED backlighting allows for reduced power consumption, a thinner depth and lighter weight. Full HD resolution delivers stunning image quality for a variety of content, and the E423’s integrated tuner and speakers allow users to enjoy high-definition broadcast capabilities. This display can be monitored remotely through the RS-232C networking feature, which also provides customers the ability to synchronize multiple displays, remotely power on/off and lock out external buttons to prevent unwanted changes in the display’s setting.
