Kystar KSV12C LED video controller
The Kystar KSV12C combines video processing and sending for an LED receiving-card system. It has 12 Gigabit Ethernet outputs, a maximum total load of 7.8 million pixels and support for three-picture display layouts.
The model-specific specification retained on this page lists five digital video inputs. Its HDMI 1.4 and DP 1.1 paths support 3840 × 2160 at 30Hz; this is an input timing, separate from the LED output’s pixel budget.
KSV12C specifications

4K input does not equal a full 4K LED canvas
A 3840 × 2160 native LED canvas contains 8,294,400 pixels, exceeding the stated 7.8-million-pixel total. By comparison, 3840 × 2000 contains 7,680,000 pixels and fits the total budget before checking port mapping and receiving-card settings.
Calculate the actual width × height, then allocate each cabinet within the per-port limit. The maximum width and height are individual dimensions and cannot both be used at their largest value as one full rectangle.
Three-picture layouts and source timing
Arrange up to three pictures for presentations or multi-source LED content within the documented configuration. Specify the source formats and window sizes for the installation. Five input connectors do not imply five simultaneous display pictures.
Use the appropriate input connection for the required resolution and refresh rate. EDID reading, modification and custom timing management help match a supported source format; confirm compatibility before committing to a 4K60 source workflow.
Installation and operation tools
- Flexible routing: supports non-rectangular port layouts to improve utilization of irregular screens.
- Cropping and border removal: adjusts the source region while maintaining the intended display layout.
- Black/freeze and key lock: provides direct operational controls and protection against accidental button input.
- Built-in test patterns: solid colors, gradients and scan lines assist screen setup.
- Image adjustment: brightness and contrast can be adjusted for the display configuration.
Frequently asked questions
Does this KSV12C configuration accept 4K at 60Hz?
The retained specification lists 3840 × 2160 at 30Hz for HDMI 1.4 and DP 1.1. Check the exact supplied hardware revision and supported timing if a project requires 4K60 input.
How many pixels can it send to the LED screen?
Up to 7.8 million pixels across 12 Gigabit outputs, with up to 650,000 pixels per output at the documented 8-bit setting.
Does it need a separate sending box?
The sending function is integrated. Its Gigabit outputs connect to compatible receiving cards, which provide the connections to LED modules.
Can I use another KSV model’s specifications?
Use the exact KSV12C document for connector count, picture layout and loading limits. The separately specified KSV24C has different input and layer capabilities.
Conclusion
KSV12C suits LED systems that need integrated processing, 12-port sending and three-picture layouts within 7.8 million pixels. Match the source timing, native screen dimensions and receiving-card configuration to the exact supplied revision.
