Direct-Lit LED Display Direct-lit LED technology delivers sharp, high-resolution images, along with the uniform brightness typical of traditional CCFL-backlit displays. It also uses less energy, with savings of up to 50% over CCFL. Step up to the performance and efficiency benefits of LED. Optional Touch Overlay Add an optional IR touch overlay accessory to enable up to 6 simultaneous touch points. Simple Connectivity A simple feature set and connectivity are perfect for many applications. Inputs include VGA, HDMI and audio out. (There’s an AV audio out if you don’t want to use the built-in 10W x 2 stereo speakers.) Commercial Reliability Samsung is the largest manufacturer of LED panels in the world. So while the ED-C Series displays are affordable, they’re also every bit as reliable as our most expensive display panels. It’s why we back them with a 3-year onsite warranty. High Resolution Samsung ED-C Series displays feature 1920 x 1080, for crisp motion graphics and easily readable text. Brightness levels are 320 nits and contrast ratio is 5000:1, for detail even in the whites and blacks.
