The Colorlight X20 is a 4K LED display controller with a maximum loading capacity of 13 million pixels. HDMI 2.0 and DP 1.2 inputs accept sources up to 4096 × 2160 at 60 Hz, while 20 Gigabit Ethernet outputs or two 10G optical outputs connect the controller to the LED system.
Source layouts and 16 scene presets
Switch, scale and crop video sources, and position overlapping windows on the screen. Up to six windows are supported, depending on the source combination. With one 4K source and four HD sources, five windows are available; with two 4K sources, the layout is limited to two windows. The minimum window and crop size is 64 × 64 pixels.
Store and recall 16 scenes for repeatable layouts. Brightness and color-temperature adjustments and improved grayscale at low brightness are supported. Precision color management requires a receiving card that supports the feature.
Output selection and optional 3D
Ethernet and optical output modes cannot be used simultaneously. Select the mode to suit the cabling and receiving system. 3D display requires corresponding accessories purchased separately; the optional 3D sync connection is used with an emitter and active 3D glasses.
