KYStar U4 LED video processor
The KYStar U4 is a multi-image display processor for spliced LED screens. The PDF identifies it as a four-window processor and describes independent window size, position and layer order. Four video outputs support horizontal, vertical and cross-spliced layouts.
Inputs and screen layouts
The listed inputs are one DVI, one HDMI, two VGA, two CVBS and one SDI, with one configurable expansion slot. Expansion choices include HDMI 1.4a, IP, DVI, HDMI 1.3 and CVBS; confirm the module fitted to the unit.
The specification gives 4096 × 2160 as the maximum input resolution for suitable HDMI 1.4 or Dual Link DVI configurations, without stating the frame rate at that resolution. Its output examples are 15360 × 400 and 960 × 6144. These are alternative layouts, not a combined 15360 × 6144 canvas.

Source clarification
The linked PDF contains inconsistent wording: its opening bullet mentions six windows, while its title and detailed U4 sections specify four. Its Ethernet-control section also names U6. This page follows the U4-specific four-window description and does not treat the U6 paragraph as verified U4 functionality. Confirm the exact hardware and software configuration if these functions are required.
U4-specific sections describe per-input brightness adjustment, transitions such as cuts, wipes and dissolves, and automatic switching to a selected backup source when the main signal fails.
Frequently asked questions
Does the U4 display four windows or six?
Its model heading and detailed U4 sections describe four windows. An opening six-window statement conflicts with those sections, so a six-window capability is not confirmed here.
Can the U4 create a 15360 × 6144 output?
The specification gives separate examples of 15360 × 400 and 960 × 6144. The maximum width and height must not be combined into an unsupported canvas.
Are all expansion input types included?
No. The expansion slot is configurable. Check the installed option for HDMI 1.4a, IP, DVI, HDMI 1.3 or CVBS input availability.
Can I add text or a logo over the video?
Yes. The U4-specific description supports an independent image/text overlay layer through KYStar control software, with stored overlay content.
