Configuration and image control
The R12 supports low-brightness grayscale processing, color transformation and arbitrary frequency multiplication. Point-by-point correction helps adjust brightness and color consistency across the display. Confirm driver-chip settings and the operating refresh rate during commissioning.
Configuration readback and repair tools support card replacement. Network diagnostics assist with cable checks, while pixel-mapping functions support special-shaped screens. Program write protection is also provided.
Frequently asked questions
What is the maximum load of the Kystar R12?
The listed maximum is 512 × 512 pixels without correction data. With correction data, the listed maximum is 512 × 320 pixels.
How many RGB data groups does the R12 output?
It outputs 24 groups of RGB data through 12 standard HUB interfaces.
Does the R12 support point-by-point calibration?
Yes. It supports brightness and chroma correction, with low-gray compensation. Use the lower specified load when correction data is enabled.
What tools are available for replacing a receiving card?
The R12 provides configuration readback and a one-key repair function. Check module wiring and configuration before putting the replacement card into service.
