The NovaStar MCTRL R5 LED display controller combines HDMI, dual-link DVI and 6G-SDI inputs with optical transmission and screen rotation. The original 4K × 1K at 60 Hz description corresponds to the manufacturer’s stated 3840 × 1080 at 60 Hz loading capacity.

Planning a rotated LED screen
Rotation depends on the receiving card and SmartLCT configuration. NovaStar documentation identifies A8s and A10s-series options, with model names varying by document version. Check the exact receiving card and firmware before ordering. Configure the screen before applying rotation; the V1.0.5 manual excludes rotation with a 10-bit input.
Optical transmission
The 10 km specification applies to the stated single-mode optical arrangement, not every fiber cable or module. Match the transmitter, receiver, fiber and connectors to the installation. The second optical channel duplicates the first rather than adding a separate screen load.

MCTRL R5 FAQ
Does MCTRL R5 support a 4K UHD screen at 60 Hz?
Its stated loading resolution is 3840 × 1080 at 60 Hz, described as 4K × 1K. Do not interpret that as 3840 × 2160 at 60 Hz.
Can I rotate the LED screen image?
Yes, with a supported receiving card and the appropriate SmartLCT configuration. Check the exact card and firmware; 10-bit input is excluded from rotation in the V1.0.5 manual.
Does Dual DVI mean two DVI inputs?
No. The manufacturer specifies one dual-link DVI input connector, alongside HDMI 1.4 and 6G-SDI.
What is required for 10 km fiber transmission?
The specified arrangement uses single-mode twin-core fiber, LC connectors and 1310 nm optics. Confirm the complete optical link before installation.
Does OPT2 add extra loading capacity?
No. OPT2 is the duplicate channel of OPT1, which carries the data for Ethernet outputs 1–8.
