Frequently asked questions
What is the maximum CS20-8K display canvas?
The V2.0 specification lists a maximum whole-system output of 8192 × 4608 at 60 Hz. Confirm the LED controller inputs and output mapping for the planned canvas.
How are playback and operator-monitor connections separated?
Four Mini DP ports are listed for playback. The HDMI 2.0 and DP 1.2 operator-interface connections are specified separately, with up to 4096 × 2160 at 60 Hz for the editing/control display.
Does CS20-8K support 120 Hz output?
The feature summary describes four 4K at 60 Hz outputs, while the V2.0 table lists a single-channel maximum of 4096 × 2304 at 120 Hz. Confirm the validated timing and workload for the supplied configuration instead of assuming every output can use that maximum simultaneously.
Which capture interfaces are available?
The document lists optional HDMI, SDI, DP and DVI capture-card interfaces and NDI acquisition support. Confirm the installed capture hardware and required live-source format.
Can the server be controlled without a separate operator monitor?
A seven-inch front touch screen provides system information and some control functions while the playback software is running. Pad app, MIDI and central-control functions are also listed; the complete setup still needs configuration and testing.
