MCTRL660 Independent LED Display Controller
The NovaStar MCTRL660 sends HDMI or DVI video to an LED display through four Gigabit Ethernet outputs. Its LCD, control knob and BACK button allow screen configuration and manual brightness adjustment without a computer, supporting rental and fixed installations.

Resolution and Model Selection
The retained PDF describes MCTRL660. It is not a specification for MCTRL660 Pro. Its video-format table distinguishes standard 8-bit input from customized 10-bit/12-bit input; the higher bit depths must not be assumed to retain the 8-bit resolution limit.
The older listing also names 2048 × 1152 and 2560 × 960 resolutions, YCrCb 4:2:2/4:4:4 formats and a light-sensor interface. These claims are not confirmed by the retained V1.4.1 connector and video-format tables. For a custom timing or those features, check the exact unit and configuration before selection.
Front-Panel Setup and Status
Press the knob to open or select menus and rotate it to choose items or adjust values. BACK returns to the previous menu. Holding the knob and BACK together for five seconds locks or unlocks the buttons. NovaStar calibration technology and the G4 engine are listed among the controller’s display functions.
The RUN indicator flashes slowly when no video is available and normally when video input is present. Rapid flashing indicates a startup image; a breathing pattern indicates Ethernet-port redundancy. The STA indicator remains on during normal operation.
Frequently Asked Questions
Can MCTRL660 configure an LED screen without a computer?
Yes. Screen configuration and manual brightness adjustment are available through the front-panel LCD, knob and BACK button. A USB Type-B connection is also provided for PC control.
What is the MCTRL660 input resolution at 10-bit or 12-bit?
V1.4.1 lists customized 10-bit/12-bit input at 1440 × 900 @ 60 Hz. Its standard 8-bit RGB 4:4:4 entry is 1920 × 1200 @ 60 Hz.
How many Ethernet outputs does MCTRL660 have?
It has four Gigabit Ethernet outputs, with a listed maximum of 650,000 pixels per port and support for redundancy between ports.
Is this specification for MCTRL660 Pro?
No. The linked V1.4.1 document is for MCTRL660. Some retained reference images had Plus/Pro filenames or labels; those images do not establish Pro specifications for this listing.
Why is the RUN indicator flashing slowly?
The retained specification identifies slow RUN flashing as video input unavailable. Check the selected input and source signal; normal flashing indicates an available video input.
Retained Reference Images
These original images are retained. Their previous filenames or labels refer to Plus/Pro; use the MCTRL660 specification for the parameters above and confirm the supplied unit’s model and panel layout.
