Colorlight X4e LED video controller
Colorlight X4e combines HD video processing and LED sending with four Gigabit Ethernet outputs and up to 2.6 million-pixel loading. Its HDMI, DVI, DisplayPort and two SDI inputs provide source options for multi-picture LED displays.
Three-picture layouts and synchronization
Three pictures can be arranged with adjustable positions and sizes. The controller supports source switching and scaling, brightness and chromaticity adjustment, and improved low-brightness grayscale. HDMI and DVI provide loop connections, while Genlock input and loop output support synchronization.
A 1.8-inch LCD, rotary knob and front-panel buttons provide source selection and display controls. USB connects a PC for configuration and supports cascading between controllers. Check source timing, cabinet mapping and receiving-card compatibility when planning the system.

Frequently asked questions
What video inputs does Colorlight X4e provide?
It provides two SDI inputs plus one DisplayPort, one HDMI and one DVI input. HDMI and DVI include loop connections.
Does X4e accept 4K input through DisplayPort?
The linked specification lists DisplayPort, HDMI and DVI input up to 1920 × 1200 at 60 Hz. The presence of a DisplayPort connector does not establish 4K input capability.
Can X4e display three sources at once?
Yes. It supports three-picture display with independently adjustable positions and sizes within the supported LED canvas.
What does the X4e 4096-pixel dimension limit mean?
The maximum width or height is 4,096 pixels, but the total display must remain within 2.6 million pixels. It cannot be treated as a 4096 × 4096 full-capacity screen.
Can X4e be synchronized with other equipment?
The specification lists Genlock input and Genlock loop output. Confirm the reference source and complete system configuration before specifying synchronized operation.
