Digital View – ALT-1920 controller board

Product Overview

The ALT-1920 LCD controller is an equivalent alternative to the ALR-1920. It combines three of the most popular input formats, HDMI, Analog RGB (VGA) and DisplayPort in a compact general purpose solution for LCD panels up to 1920×1200 resolution. One of the key features of this compact highly reliable controller is the low signal latency from input signal to panel output signal. In addition the controller now uses ceramic capacitors to further improve reliability.
