HDMI connectivity enables single-jack porting of high-definition television and movie files from Mac and PC computers, as well as external drives or receivers. "SmartContrast" technology helps to increase overall clarity and vividness of colour, with automatically-adjusting parameters for the user's convenience. Manual interaction is achieved via "SmartTouch" controls, a set of touch-sensitive lighted sensors on the front of the unit. Users can also manually toggle between two primary aspect ratio modes, including the standard 4:3 setting as well as a widescreen 16:9 function. In addition, the 234EL2SB/27 features an integration stereo speaker system with a variety of customizable options, including front, rear, top and down-firing directions for optimal performance in any room type.
