Colorlight S20 4K LED Display Controller
The Colorlight S20 is an LED sending box with one DisplayPort 1.2 input, one HDMI 2.0 input and 20 Gigabit Ethernet outputs. It accepts video up to 4096 × 2160 at 60 Hz and drives up to 8.85 million LED pixels. Seamless source switching and Ethernet-port or controller redundancy support installations that need flexible signal routing.
Plan the screen and port loading
The maximum screen width or height is 8192 pixels, within the total loading capacity. Each Ethernet port supports up to 650,000 pixels and a maximum width or height of 4096 pixels. Per-port loading capacity decreases when the height exceeds 1280 pixels, so the port layout must be checked against the actual cabinet arrangement.
USB cascading and RS232 protocol control support system configuration. Separate audio input and output are provided. Optional 3D display support is listed in the specification; confirm the required configuration and accessories for a 3D installation. The S20 supports Colorlight receiving cards and multifunction cards.
