ALC-1920 LCD Controller

The ALC-1920 combines three of the most popular input formats, HDMI, DisplayPort, and USB-C in a compact general purpose solution for LCD panels up to 1920x1200 resolution. It is an excellent board to start with for panel and project evaluation as well as ideal for many display products. 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.

The ALC-1920 is similar to the long running models ALR-1920 and ALT-1920.
