HLT-1920 LCD Controller Board

The HLT-1920 LCD controller is the harsher environment version of the ALT-1920. It combines three of the most popular video input formats, HDMI, Analog RGB (VGA) and DisplayPort in a compact general purpose solution for LCD panels up to 1920x1200 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 uses ceramic capacitors to improve reliability and lifetime at elevated temperatures.
