NovaStar MCTRL R5 LED display controller
The NovaStar MCTRL R5, also searched as MCTRLR5, is an independent LED controller for displays that require rotation and flexible screen layouts. The manufacturer’s V1.0.1 specification lists a loading capacity of 3840 × 1080 at 60 Hz. This is the documented 4K × 1K format, rather than a full 3840 × 2160 at 60 Hz screen.
Screen rotation and receiver compatibility
Arbitrary-angle rotation requires the MCTRL R5 to work with A8s or A10s receiving cards and SmartLCT. Confirm those receiving cards and the intended screen layout before selecting the controller for a rotated LED installation.
The controller also supports front-panel screen configuration, manual brightness adjustment, pixel-level calibration, white-balance calibration and color-gamut mapping. The front USB port accepts a USB drive for firmware upgrade; computer control uses the rear Ethernet or USB IN connection.

Fiber connection planning
OPT1 carries the data corresponding to all eight Ethernet outputs, while OPT2 is its backup. The previous listing stated a 10 km transmission distance, but the linked V1.0.1 specification does not define the optical module or fiber conditions for that distance. Confirm the optical modules, fiber type and required distance before installation.
Use the input connector that matches the source, then check the screen pixel map and rotation requirements. Do not connect the Type-A USB interface directly to the control computer; the specification identifies USB IN and Ethernet as the computer-control paths.

Frequently Asked Questions
Can the MCTRL R5 rotate an LED screen at any angle?
Yes, the documented rotation function works with A8s or A10s receiving cards and SmartLCT. Verify this receiver and software combination for the planned screen.
Does the MCTRL R5 support a full 4K UHD screen at 60 Hz?
The linked specification lists 3840 × 1080 at 60 Hz loading, commonly described as 4K × 1K. It does not specify 3840 × 2160 at 60 Hz as the loading capacity.
Which video inputs are available on the MCTRL R5?
It has one HDMI 1.4 input, one dual-link DVI input and one 6G-SDI input. Choose the input path to match the video source and required timing.
What is the difference between OPT1 and OPT2?
OPT1 corresponds to Ethernet outputs 1–8. OPT2 is the backup optical channel for OPT1, according to the V1.0.1 specification.
Is a 10 km fiber connection guaranteed with every MCTRL R5 setup?
No universal 10 km connection is established by the linked specification. That distance appeared in the original listing, but the module and fiber requirements were not documented there. Confirm the actual optical components and link distance before ordering.
