Easy Interactive Video Wall Without a Splitter 

Easy Interactive Video Wall Without a Splitter

Analog Daisy Chaining is the easiest way to build a video wall. You can simply connect up to 9 displays through VGA cables without using splitters; the screen can show a mirrored image or form a 3x3 configuration for an enlarged viewing area.

Picture-in-Picture (Pip) & Picture-by-Picture (PbP) Modes 

Picture-in-Picture (Pip) & Picture-by-Picture (PbP) Modes

The picture-in-picture and picture-by-picture modes enable the screen to display content from two independent video sources simultaneously for more convenience and flexibility. You can resize or relocate the picture anywhere on the screen for maximum effect.

Energy Saving Ambient Light Sensor

An integrated sensor automatically adjusts screen brightness according to the lighting condition of the surrounding environment to optimize the image and reduce power when it's not needed. As the brightness adjusts to the ambient light, the display can reduce energy consumption by 40% to 50%.
