KYStar S6 LED sending box
The KYStar S6 connects an HDMI 1.3 or DVI video source to an LED display system through six Gigabit Ethernet outputs. It accepts input up to 2048 × 1152 at 60 Hz and supports a maximum total load of 2.35 million pixels.
Screen configuration and control
EDID management allows custom resolutions within the specified input limits. Arbitrary cross-connection lets unused areas remain outside the pixel load, while Ethernet hot backup supports redundant signal paths. The device also supports brightness and color-temperature adjustment and calibration with a compatible KYStar calibration system.
Use USB-B or the Gigabit control ports for PC communication. Up to eight units can be cascaded for control. Rental stages, conference rooms and exhibition screens are typical applications, subject to the receiving-card and screen configuration.

Frequently asked questions
Is the S6 a 4K-input sending box?
No. Its specified maximum HDMI and DVI input resolution is 2048 × 1152 at 60 Hz. Custom resolutions must remain within the documented limits.
Do six output ports provide 3.9 million pixels in total?
No. Although each Ethernet output supports up to 650,000 pixels, the total S6 load is limited to 2.35 million pixels.
Can multiple S6 units be controlled together?
Yes. The Gigabit control connections support cascade control for up to eight units.
Can the S6 calibrate an LED screen without a video source?
The specification supports source-independent brightness and color calibration when used with the compatible KYStar calibration system.
