Colorlight Z4 LED controller overview
The Colorlight Z4 brings video processing, splicing and LED sending together in one controller for rental LED walls and fixed installations. It accepts multiple video sources, scales the image to the screen layout and supports an adjustable picture-in-picture (PIP) window. The Z4 is designed for projects that need coordinated output across multiple controllers.

Plan the input and output connections
Colorlight’s Z4 specification V1.6 lists one HDMI input with loop, one DVI input with loop, two SDI inputs and one DP input. The earlier description of this listing names VGA instead of DP. Check the rear-panel image and the exact hardware revision before ordering or preparing cables. This page retains both original panel photos for that check.
The current listing identifies four Gigabit Ethernet outputs and two LC fiber outputs. Confirm the receiving-card and fiber-converter arrangement against your project design and the linked manual before installation.
What does “4K” mean for this Z4 listing?
The legacy product name and URL include “4K UHD.” Colorlight’s Z4 documentation specifies a maximum input of 1920 × 1200 at 60 Hz and a total LED load of 2.3 million pixels. The 4096-pixel width and height figures are separate dimension limits; they do not mean the unit can drive a full 4096 × 2160 canvas from one controller. Use the documented input and total-load limits when sizing a display.

Conclusion
The Z4 is a combined LED controller and video processor suited to a 2.3-million-pixel display design with PIP and synchronized multi-controller operation. Size the project using its documented 1920 × 1200@60 Hz input and total pixel capacity, and verify the physical input ports on the supplied unit.
