Colorlight K10 receiving card
Colorlight K10 is a receiving card for fine-pitch rental and fixed LED screens. It supports up to 512 × 512 pixels, 12-bit video input/output, HDR10 and HLG. High-density connectors connect the card to a compatible cabinet HUB board or module.
Calibration and cabinet maintenance
Multi-layer and low-grayscale calibration process correction data for different brightness levels. Independent gamma adjustment, Infi-bit processing and grayscale refinement provide additional display adjustment tools. Grayscale refinement uses a luminance meter to measure the actual screen.
Cabinet highlight, OSD, seam correction and image rotation help with setup. A pre-stored picture can appear when the video signal is absent. The card supports firmware upgrades without a power restart, along with loop, receiving-card, power-supply, firmware, configuration and calibration-data redundancy. These system functions require the appropriate cabinet design and configuration.

Match the HUB pinout, driver IC, scan mode and firmware before replacing a card. High-frame-rate operation, including 120/144/240 Hz, changes loading capacity. Cabinet humidity, power, pixel and fan monitoring require supporting sensors and cabinet connections.
Frequently asked questions
What is the maximum loading capacity of Colorlight K10?
The specification lists 512 × 512 pixels. Enabled features and high frame rates can affect the available capacity, so verify the intended cabinet configuration.
Does K10 support 12-bit video and HDR?
Yes. The specification supports a maximum 12-bit video input/output path and lists HDR10 and HLG. Its 14-bit calibration accuracy is a separate parameter.
What does K10 multi-layer calibration do?
It stores correction coefficients for different brightness levels and adjusts them according to the displayed content to improve uniformity across gray levels.
Can K10 display an image when the video signal is lost?
Yes. The pre-stored picture function allows a customized image to be displayed when no video signal is present.
Can K10 replace another receiving card without configuration?
Do not assume direct interchangeability. Check the board model, connector pinout, HUB board, module driver IC, scan mapping, power supply and saved parameters before replacement.
