Colorlight S4 LED Display Controller Box
The Colorlight S4 is a 1U LED display sending box for connecting an HDMI or DVI video source to a Colorlight receiving-card system. Its four Gigabit Ethernet outputs carry display data to LED cabinets and support flexible screen splicing. The S4 supports an input resolution up to 1920 × 1200 pixels and an LED screen loading capacity up to 2.3 million pixels.

How the S4 fits an LED display system
Connect the video source to the S4’s HDMI or DVI input, then connect its Ethernet outputs to the display’s receiving-card chain. Use the USB interfaces for PC configuration and cascading multiple sending boxes where the installation requires them. Screen mapping must stay within both the 2.3 million-pixel total and the stated maximum width and height; the input-resolution limit describes the source signal, not a promise that every 4096 × 2560 canvas can be loaded.
Practical features
- Four Gigabit Ethernet outputs support flexible splicing across the LED screen.
- Brightness and chromaticity adjustment help tune the display.
- Improved grayscale performance at low brightness.
- HDCP support for applicable protected sources.
Frequently asked questions
What is the S4’s maximum loading capacity?
Up to 2.3 million LED pixels in total. The 4096-pixel maximum width and 2560-pixel maximum height are separate dimension limits, not a 4096 × 2560-pixel loading specification.
How many LED outputs does the Colorlight S4 have?
It has four Gigabit Ethernet outputs for connections to Colorlight receiving cards.
Can the S4 accept HDMI and DVI sources?
Yes. It provides HDMI and DVI signal inputs, with a maximum input resolution of 1920 × 1200 pixels.
