Colorlight CS16K Multimedia Server
The Colorlight CS16K is a 5U multimedia playback and control server for complex LED display layouts. With GrandShow software, it can decode and play two 8K videos and deliver eight 4K@60Hz video outputs. It is suited to ultra-wide screens, irregular canvases and multi-screen installations that need scene control and synchronized playback.
Key capabilities
- Eight DP 1.4 outputs: up to 4096×2304@60Hz per output, with a maximum overall output of 16384×4608@60Hz.
- Flexible content: play video, graphics, presentations, text, web pages and streaming media; 10-bit HDR decoding and playback is supported.
- GrandShow workflows: edit, preview, save and switch scenes; use multiple layers, timeline playback, transitions and scheduled operations.
- Creative LED layouts: arrange split screens, rotated content, ultra-wide canvases and irregularly shaped displays.
- Control and monitoring: NDI reception, MIDI control, central-control protocol, Pad app control, output preview, performance logs and fault warnings.
- Continuity: supports multi-server master/slave backup and server 3D sync signals.

Frequently asked questions
What is the maximum CS16K output?
The CS16K datasheet specifies eight DP 1.4 outputs and a maximum overall point-to-point output of 16384×4608@60Hz. Each DP output supports up to 4096×2304@60Hz.
Can CS16K play content on irregular LED screens?
Yes. GrandShow supports screen splitting, irregular splicing, rotation, multiple layers and scene switching. The actual layout depends on the downstream display configuration.
Are HDMI, SDI and DVI inputs included?
The datasheet lists HDMI, SDI and DVI capture cards as optional. Check the chosen configuration before purchase.
