Screen layout and processing
Video-controller mode provides layer and scaling functions. For irregular screen arrangements, loading is calculated from the combined cabinet resolutions rather than an enclosing rectangle; blank areas do not count toward the load. Confirm the cabinet mapping, port allocation and input format for the proposed screen.
Calibration, delay and monitoring
Full-grayscale calibration works with the NovaStar high-precision calibration system and C3200 scientific-grade camera to generate coefficients for gray levels. Pixel-level brightness and chromaticity calibration helps align output across the display. These functions depend on the corresponding calibration equipment and configuration.
The listed low-latency figure applies at the controller, not the entire camera-to-screen chain. Low-latency operation is described without a load reduction; additional frame delay can also be configured when required. Device and display status monitoring provide fault and alarm information.

KU20 FAQ
What is the KU20 maximum loading capacity?
The listing specifies up to 3.9 million pixels through six network outputs. Check the selected input and screen configuration against the manual.
Does KU20 have an HDMI loop output?
Yes. Its HDMI 1.3 input includes a loop output.
Which operating mode provides scaling?
Video-controller mode provides layer and scaling functions. The listed scaling options are custom and pixel-to-pixel.
Does zero-frame latency mean the entire system has no delay?
No. The stated zero-frame, less-than-1-ms figure applies to the controller side. Source processing, receiving cards and the display contribute separately to system latency.
Do blank areas of an irregular screen consume loading capacity?
The described mapping uses the sum of cabinet resolutions, so blank areas outside the mapped cabinets do not count toward the load. Keep the actual cabinet and port configuration within the supported limits.
