Colorlight Z4 Pro 4K LED Video Controller
The Colorlight Z4 Pro (Z4Pro) is a professional video processor and LED display controller for live events, broadcast, television and filming. It accepts 4K sources through HDMI 2.0, DisplayPort 1.2 and 12G-SDI, then crops, scales and arranges the picture for the LED wall.
This model provides 10 Gigabit Ethernet outputs and one 10G fiber output, with the output mode selected between Ethernet and fiber. Its maximum load is 6.55 million pixels at 60Hz with 8bit output. Input resolution and LED output capacity are different specifications; check both when planning a screen.

Video Processing for Events and Broadcast
4K source handling and three-layer layouts
Connect a media server, presentation computer or compatible broadcast source through the appropriate video input. Use cropping and scaling to fit content to the wall, and arrange up to three layers for a presentation, live camera feed or event graphics. Check the source timing and each layer’s requirements during system design.
HDR, Genlock and latency
HDR10 and HLG support provides a path for HDR content when the source, receiving cards and LED display are configured appropriately. Genlock input and loop help synchronize controllers to an external reference. The specification lists a minimum one-frame low-latency mode and a minimum zero-frame processing mode; actual system latency depends on the operating mode and the complete signal chain.
Color adjustment and control
Adjust hue, saturation, contrast, brightness compensation, color temperature and individual RGB channels. USB, RS232 and LAN connections support device control and integration. Configure Ethernet port backup or controller redundancy to suit the installation’s continuity requirements.
Plan Your LED Display Connection
- Calculate the wall’s pixel count: multiply its pixel width by its pixel height, then check the capacity for the intended frame rate and color depth.
- Plan each output port: distribute cabinets within the per-port limits and allow for the chosen backup arrangement.
- Choose Ethernet or fiber: the fiber output carries the data corresponding to Ethernet ports 1–10. It does not add a second independent pixel budget.
- Confirm the receiving system: verify your LED receiving cards, cabinet configuration and firmware before installation.

Frequently Asked Questions
Does the Z4 Pro have 10 or 20 Ethernet outputs?
The Z4 Pro has 10 Gigabit Ethernet outputs. Use the model-specific Z4 Pro specification when comparing products listed together in Colorlight’s Z5/Z4 Pro range.
Can one Z4 Pro drive a full 3840 × 2160 LED wall at 60Hz?
That wall contains 8,294,400 pixels, which exceeds the Z4 Pro’s 6.55-million-pixel limit at 60Hz/8bit. Accepting a 4K source does not mean one unit can drive every pixel of a native 4K LED wall. Choose a suitable controller arrangement for the actual output load.
Is the optical module included?
The specification identifies the 10G SFP+ optical module as a separate purchase. Confirm the module, fiber type and receiving-end equipment for the required transmission distance.
Is Z4 Pro the same model as Colorlight Z4?
No. This listing is for Colorlight Z4 Pro. Match the complete model name when selecting hardware, manuals and firmware.

Conclusion
The Colorlight Z4 Pro combines 4K input, three-layer processing, HDR and Genlock with a 10-port LED output system. It is a practical choice for projects within its frame-rate and color-depth capacity limits. Confirm the screen load, receiving cards and fiber accessories to build a compatible installation.
