Colorlight X3 LED display controller
The Colorlight X3 controls LED displays of up to 2.60 million pixels through four Gigabit Ethernet outputs. One HDMI and two DVI inputs accept video up to 1920×1200 at 60Hz. Input switching, scaling, cropping and screen offset let you fit a source to the display without changing the source layout.
Connections and operation
Front-panel keys select HDMI, DVI 1 or DVI 2 and adjust brightness. Connect USB IN to a computer for configuration; USB OUT connects to the next controller for cascading. The audio input works with a multifunction card. Brightness and chromaticity adjustments, low-brightness grayscale performance and HDCP 1.4 support are documented in the X3 specification.

Choosing the X3 for an LED screen
Compare the screen pixel count and cabinet mapping with the X3 loading limit. The maximum width and height are separate limits, not a supported 4096×2560 canvas. For an existing Colorlight installation, check the receiving-card configuration and required accessories before replacement or expansion.
