The NovaStar MCTRL4K LED display controller supports a single-unit loading capacity up to 4096 × 2160 at 60 Hz. DisplayPort, HDMI and dual-link DVI inputs serve different source configurations, with 16 Neutrik Gigabit Ethernet ports and four optical ports for LED display connections.

Screen configuration and calibration
The controller supports front-panel screen configuration without a PC, manual brightness adjustment and cascading for uniform control. For dual-link DVI sources, mosaic and multi-card modes provide different ways to arrange the input images; multi-card mode allows the unit to operate as two controllers.
The original feature set includes NovaStar’s G4 engine, pixel-level calibration, white-balance calibration and color-gamut mapping. Set these functions for the receiving-card system and installed firmware rather than assuming one setting suits every LED cabinet.
Planning a 4K input and fiber connection
V1.1.0 specifies 4096 × 2160 at 60 Hz with NVIDIA graphics-card timing setup for the listed HDMI/DP modes. At 10-bit/12-bit RGB or YCbCr 4:4:4, its table instead lists 3840 × 1080 at 60 Hz. Select the interface, sampling format and bit depth together.
The same document maps OPT1 to Ethernet ports 1–8 and OPT2 to ports 9–16. OPT3 duplicates OPT1, and OPT4 duplicates OPT2 for backup. The four optical ports should not be treated as four independent additions to loading capacity.

MCTRL4K FAQ
Does MCTRL4K support 4096 × 2160 at 60 Hz?
Yes, this is its listed maximum capacity, with input-format and timing conditions. Check the HDMI/DP sampling and bit-depth requirements above before configuring the source.
Can I configure an MCTRL4K without a computer?
The controller supports front-panel screen configuration and manual brightness adjustment without a PC. Use the matching manual for the available setup options.
What do mosaic and multi-card modes do?
They are operating modes for the dual-link DVI inputs. Multi-card mode lets the MCTRL4K function as two controllers; choose the mode that matches the input-image arrangement.
Are all four optical ports independent outputs?
No. V1.1.0 assigns two primary optical channels and two duplicate backup channels. Review the port mapping above when planning redundancy.
Is MCTRL4K power consumption 10 W or 30 W?
The original page stated 10 W, but NovaStar V1.1.0 lists a rated 30 W. The discrepancy is retained explicitly; confirm the supplied unit’s rating before designing its power provision.
