Kystar KSV6C for a 3.9-million-pixel LED wall
The Kystar KSV6C combines video processing and LED sending in one controller. It has six Gigabit Ethernet outputs, supports up to 3.9 million LED pixels, and accepts three digital sources through HDMI 1.4, HDMI 1.3 and DVI-D. It is designed for small-pitch display control, including presentation walls that need more than one source on screen.
The six outputs provide an intermediate capacity between smaller controllers and higher-port models. Select the KSV6C by the actual LED canvas size and cabinet mapping, then check that each connected source meets the documented input timing.

Useful tools for screen configuration
- Three-picture display: arrange digital sources to suit a presentation or multi-source viewing layout.
- EDID management: read, modify or customize the source display information for the intended signal.
- Source cropping: remove borders or select the required part of an input image.
- Commissioning patterns: display solid colors, gradients and scanning lines while inspecting the LED screen.
- On-site operation: use black screen, freeze, key lock, brightness and contrast controls.
Plan the LED pixel budget before ordering
The HDMI 1.4 input can accept 3840 × 2160 at 30Hz, but the controller’s LED load remains 3.9 million pixels. A complete native 3840 × 2160 LED screen contains 8,294,400 pixels and exceeds that output budget. Likewise, 3840 × 1080 contains 4,147,200 pixels: accepting that source timing does not mean the whole image can be sent to an LED canvas at its native pixel count.
A 2560 × 1440 LED canvas contains 3,686,400 pixels, below the stated total limit. This is a pixel-count example; successful configuration still depends on cabinet geometry, receiving cards, output settings and keeping each Ethernet port within its own capacity. The maximum width and maximum height are separate constraints and cannot be combined into one maximum-size rectangle.
Confirm the receiving-card model, firmware, signal timings and cable plan for your project. The retained KSV6C specification shows Ethernet outputs; check the supplied hardware revision before planning fiber accessories. If the display needs more LED pixels, compare the 8-port KSV8C or 12-port KSV12C using their individual capacity and input specifications.
Frequently asked questions
What is the KSV6C maximum LED load?
The model-specific specification lists 3.9 million pixels across six Gigabit outputs, with up to 650,000 pixels per output at 8-bit output.
Can KSV6C accept full 4K at 60Hz?
The documented HDMI 1.4 timing is 3840 × 2160 at 30Hz, or 3840 × 1080 at 60Hz. Full 3840 × 2160 at 60Hz is not listed.
Is a separate sending box required?
LED sending is integrated with the video processor. A compatible LED receiving-card system remains necessary at the screen.
Conclusion
Choose KSV6C when your LED wall fits the 3.9-million-pixel output budget and needs three digital sources with flexible layouts. Verify the input timings and per-port mapping before deployment.
