The NovaStar CX80 Pro COEX LED display controller uses selectable input cards, sixteen 5 Gbps Ethernet outputs and two 40 Gbps optical ports. It supports VMP control for high-resolution LED systems. Choose the input card and signal format together; the 8K label does not apply equally to every connector.

Input card 1: connector-specific limits
The linked V1.1.2 manual specifies HDMI 2.1 input at 7680 × 4320 with frame rates up to 60 Hz. Its DP 1.4 input uses 7680 × 4320 at 30, 25 or 24 Hz. Each 12G-SDI connector is limited to 4096 × 2160 at 60 Hz; SDI mosaic combines sources.
On that card, HDMI and DP are documented for the stated 7680 × 4320 timings rather than arbitrary custom resolutions. Higher bit depth and color sampling impose further timing conditions. Verify the exact source format in the manual before choosing the card.
LED system planning
Keep the two Ethernet control ports separate from the sixteen LED output ports in the wiring plan. Match the controller outputs to supported receiving equipment and the chosen optical link. Connector bandwidth alone is not a complete screen-loading specification.

CX80 Pro FAQ
Does every CX80 Pro connector accept 8K at 60 Hz?
No. On input card 1, HDMI 2.1 supports the documented 8K timings up to 60 Hz, while DP 1.4 is listed up to 30 Hz at 7680 × 4320. Individual 12G-SDI inputs are 4K-class.
Which input card has four HDMI 2.0 connectors?
Input card 2 combines four HDMI 2.0 and four 12G-SDI connectors.
Can multiple input signals be spliced?
Input mosaic is supported for the listed 12G-SDI and HDMI 2.0 interfaces. Follow the card-specific timing and mosaic settings.
Are the two control Ethernet ports extra LED outputs?
No. They are listed as control connections, separately from the sixteen 5 Gbps LED output ports.
Does CX80 Pro provide digital audio and Genlock?
Yes. It has SPDIF digital audio output and a Genlock input with loop output.
