Window layouts and spliced displays
Each of the six windows can be resized, positioned and layered independently. Horizontal, vertical and cross-splicing layouts are supported, along with custom output resolution and refresh-rate settings. The quoted horizontal and vertical limits describe different layouts; they do not form a single 15360 × 6144 output canvas.
The U6 also supports image and text overlays through Kystar control software. Window and preset transitions include cuts, dissolves and wipes. CPT+FST splicing processing and image scaling are provided for LED display layouts.
Monitoring and source backup
Local monitoring can show the output, preview six inputs or combine both views. Ethernet control provides parameter adjustment, layout management and monitoring through the control software. A selected backup input can take over when the primary source fails and return to the primary source when it recovers.
Frequently asked questions
How many windows can the Kystar U6 display?
It supports six simultaneous image windows with independent size, position and layer order.
Does every U6 input accept 4K?
No. The listed 4096 × 2160 input capability requires a suitable 4K input configuration, such as the specified HDMI 1.4 or Dual Link DVI arrangement. Check the installed input option and supported timing.
How many DVI outputs does it have?
The U6 has four DVI outputs for spliced display layouts. Listed examples include 15360 × 600 and 1536 × 6144.
Can I preview the sources before switching?
Yes. Local monitoring supports output monitoring, six-input preview and combined monitoring/preview. Ethernet monitoring is also listed.
What happens if an input signal fails?
The hot-backup function can switch to a configured backup source and return when the primary signal recovers. A backup source must be connected and configured.
