The NovaStar MCTRL600 is a standalone LED display controller, also called a sending box, that accepts one DVI, one HDMI 1.3 and one audio input and distributes the picture to LED panels through four Gigabit Ethernet outputs, each rated for up to 650,000 pixels. A single unit accepts input resolutions up to 1920×1200@60Hz, is configured from a PC with NovaStar NovaLCT software over a USB Type-B cable, and can be cascaded with up to 20 controllers over UART.

This page is the practical part of the MCTRL600 manual: verified specifications, indicator-light meanings, NovaLCT setup steps, manual and firmware downloads, what drives the price and the fixes for the most common setup problems. The specification figures come from NovaStar’s MCTRL600 LED Display Controller Specifications V2.3.4 (released 2025-06-05) and from NovaStar’s MCTRL600 product page.

In short: the MCTRL600 suits screens that run from a single 1920×1200@60Hz source and stay within 650,000 pixels per Ethernet output (2.6 million pixels across the four outputs, calculated from that per-port rating). It has no built-in media player, no multi-window switching, no 4K input and no network control port. If you need any of those, read section 9 before you buy.

The MCTRL600 is an LED display controller developed by Xi’an NovaStar Tech Co., Ltd. It is a controller rather than an all-in-one video processor: it converts a video signal into the data that LED receiving cards need and sends that data to the screen over Ethernet. NovaStar lists rental and fixed installations as its main applications, including concerts, live events, security monitoring centres and sports venues.

MCTRL600 key features

• Inputs: 1× SL-DVI, 1× HDMI 1.3 and 1× audio connector. The HDMI input is HDCP 1.4 compliant.
• Outputs: 4× RJ45 Gigabit Ethernet, up to 650,000 pixels per port, with redundancy between the Ethernet ports.
• Control: 1× Type-B USB 2.0 port for communication with a PC running NovaLCT.
• Cascading: 2× UART ports (IN/OUT) so that up to 20 MCTRL600 units can be linked and controlled together.
• Ambient light: a light sensor connector allows automatic screen brightness adjustment.
• Calibration: pixel-level brightness and chroma calibration when the controller works with NovaLCT and a calibration platform.
• Signal formats: RGB, YCrCb 4:2:2 and YCrCb 4:4:4.

Every value in the table below comes from NovaStar’s MCTRL600 LED Display Controller Specifications, document version V2.3.4, released on 2025-06-05. Where a second official source states a different figure, both values are listed underneath the table instead of being averaged.

Source note – where the two official documents differ. NovaStar’s specification PDF (V2.3.4, 2025-06-05) and the electrical/labelling table on NovaStar’s MCTRL600 product page do not agree on every value. The product page states a rated power consumption of 16 W, a weight of 2.9 kg, humidity from 0% RH to 90% RH, a 1U space requirement and certifications of FCC, RoHS, EAC, IC, PFOS, LVD and EMC; the PDF states 6.6 W, 2.5 kg, 10% RH to 90% RH and CE, FCC, IC, CB and PSE. The two documents also give different packing-box dimensions. Before you specify or ship a unit, confirm the value against the label on the controller you receive and against the hardware revision datasheet, because a change of revision can change the certification set.

The MCTRL600 has two video inputs, and each one has its own resolution ceiling that depends on the bit depth of the source. This is the part of the MCTRL600 specification that most often decides whether the controller fits a project.

Three further limits follow from the same document and are worth checking before a show:

• Interlaced sources are not supported on either input. Set the source to a progressive format before you connect it.
• Custom resolutions are supported up to 3840 pixels wide (3840×600@60Hz) or 3840 pixels high (548×3840@60Hz). LED walls that are wider or higher than 1920 or 1200 pixels therefore use a custom timing rather than a standard 16:9 one.
• 10-bit and 12-bit sources top out at 1440×900@60Hz. If your project needs both deep colour and full 1920×1200, the input cannot deliver both at 60Hz.

The front panel carries two indicator lights, and their flashing pattern tells you what the controller is doing. The descriptions below are the ones printed in NovaStar’s specification document.

Rear panel connectors

• Input: DVI IN (SL-DVI), HDMI IN and AUDIO.
• Output: 4× RJ45 Gigabit Ethernet ports for data to the receiving cards, with redundancy between the ports.
• Functionality: the light sensor connector for automatic brightness adjustment.
• Control: the Type-B USB 2.0 port for the control PC.
• Cascading: UART IN and UART OUT for linking up to 20 controllers.
• Power: AC 100-240V~50/60Hz. The controller must be placed horizontally and is not designed for vertical or upside-down mounting.

The MCTRL600 has no screen or buttons for configuration. Everything – screen size, receiving-card layout, input resolution and brightness – is set from a Windows PC through NovaStar’s NovaLCT software, using the USB Type-B port on the rear panel. The light sensor and the pixel-level brightness and chroma calibration are also handled inside that workflow, together with NovaStar’s calibration platform.

Documents and files for the MCTRL600

• MCTRL600 LED Display Controller Specifications, V2.3.2 (PDF) – the version hosted on this site. NovaStar has since released V2.3.4 (2025-06-05), which updates certification information and the video source specifications, so treat the V2.3.4 figures in section 2 above as the current ones.
• MCTRL600 firmware package V4.8.0.0 (ZIP) – a stored firmware build for the controller. NovaStar’s MCTRL600 product page currently lists firmware V4.9.3.0.STD, so check the release notes for the build your unit needs before you flash anything.
• Complete NovaLCT software download list – NovaLCT builds and their user manuals, including the LED configuration tool for synchronous control systems used with the MCTRL600.
• NovaStar LED software download page – the main software hub for NovaLCT, NovaStudio and the related NovaStar utilities.

Do you need a USB driver for the MCTRL600?

If the control PC does not detect the controller after you connect the USB cable, install the USB driver that ships with the NovaLCT installation package, then reconnect the cable and check the device in Windows Device Manager. A missing or outdated driver is the usual cause of a “controller not found” message, followed by a charge-only USB cable and the wrong USB port on the PC.

This sequence follows the order used in NovaStar’s controller documentation, and it applies to a single MCTRL600 working with NovaLCT on a Windows PC.

Step 1 – Install NovaLCT on the control PC

Download and install NovaLCT from the NovaLCT download list, then restart the PC so that the USB driver is registered before you connect the controller.

Step 2 – Connect power, video and Ethernet outputs

Connect the power cord, the DVI or HDMI source and the RJ45 cables that run to the receiving cards. Check that the source is set to a progressive format no higher than 1920×1200@60Hz, because interlaced signals are not accepted.

Step 3 – Connect the USB cable and confirm detection

Use the Type-B USB port. The RUN indicator should start flashing once a valid video input is present, and NovaLCT should list the controller. If it does not appear, see the driver note in section 5.

Step 4 – Create the screen and configure the receiving cards

In NovaLCT, create a screen with the real width and height of the LED wall, then map the receiving cards to the four Ethernet outputs. Each output is rated for up to 650,000 pixels and up to 512 receiving cards, so plan the cabinet layout inside those two limits.

Step 5 – Set the input resolution and check the picture

Set the wall output resolution and then confirm the incoming timing. If part of the picture is missing, reduce the source resolution or switch to a custom resolution that fits inside the width and height limits given in section 3.

Step 6 – Adjust brightness and run calibration

Set the screen brightness and use the light sensor connector if the installation should follow ambient light. For colour uniformity across cabinets, run the pixel-level brightness and chroma calibration with the calibration platform.

Step 7 – Save and back up the configuration

Send the configuration to the controller, then save a copy of the NovaLCT project file on the control PC and on a second drive. If a controller is replaced on site, the saved file is what makes a fast swap possible.

Most MCTRL600 faults show up in the indicator lights, in NovaLCT or in part of the picture. The table below links each symptom to the check that resolves it most often.

If a controller has to be replaced during an event, keep the saved NovaLCT configuration file and a spare unit with matching firmware so that the wall can be restored without rebuilding the screen map from scratch.

The MCTRL600 is normally quoted as part of a control system rather than as a single fixed list price, and the figure you see online often refers to a different configuration. These are the factors that move the price of a genuine NovaStar MCTRL600:

• What is included. A device-only controller, a complete set with carrying case, power cord, USB cable, DVI cable and cascading cable, and a full control package with receiving cards are three different quotations.
• Certification and market. The certification set differs between NovaStar’s documents (CE, FCC, IC, CB, PSE in the specification PDF; FCC, RoHS, EAC, IC, PFOS, LVD and EMC on the product page). If a project needs a specific approval, confirm it before you order.
• Quantity and spares. Events usually buy controllers in pairs or with a spare, which changes the per-unit price.
• Shipping, duty and lead time. Air freight, import duty and the delivery date for a project all sit on top of the unit price.
• Warranty and technical support. A warranty period, spare parts supply and configuration support from the supplier are part of the value, especially for rental companies.
• Software and documentation. NovaLCT, the firmware build and the calibration workflow should come with the controller; paying extra for the software that is required to configure the unit is a warning sign.

Because prices change with the market and the exchange rate, ask for a current quotation for the exact configuration you need: number of controllers, receiving cards, cables, certification and delivery date.

Decide this from the source resolution and the pixel count of the wall, not from the size of the cabinet. The comparison below uses the figures published for each controller.

Choose the MCTRL600 when

• The wall runs from one source at up to 1920×1200@60Hz and stays inside 650,000 pixels per Ethernet output.
• You want both DVI and HDMI available, for example a media player plus a laptop.
• The installation needs automatic brightness from a light sensor, or pixel-level calibration for a fixed installation.
• The screen is a rental or fixed wall that will be set up and re-used with a saved NovaLCT configuration.

Look at another NovaStar controller when

• The wall is smaller and two Ethernet outputs are enough: read the NovaStar MCTRL300 user manual, specs and NovaLCT setup guide.
• You need 4K input, several windows or scaled video: the Novastar MCTRL4K LED display controller guide covers that class of controller.
• You need more ports or a different capacity step: compare the Novastar MCTRL500 and the NovaStar MCTRL1600, and the MCTRL660 guide if the MCTRL660 family is also under consideration.
• Long cable runs between the control position and the wall are a concern: a fibre converter such as the Novastar CVT10 is added in front of the controller.

If you are still at the stage of choosing the wall itself, start with the LED screen buying guide and the rental LED display guide, then return to the controller choice.

The NovaStar MCTRL600 is a straightforward, well-documented controller: one DVI input, one HDMI 1.3 input, one audio input, four Gigabit Ethernet outputs at up to 650,000 pixels each, up to 20 cascaded units over UART, and configuration from a PC with NovaLCT. Its limits are just as clear – no 4K input, no interlaced signals, no built-in media player and no network control port.

If the wall you are planning fits those limits, the next step is to confirm the source resolution against section 3, plan the receiving-card map against the 650,000-pixel and 512-card limits per output, and keep a saved NovaLCT configuration with the spare controller. For the screens that the MCTRL600 typically drives, see the stage LED display, LED advertising screen and conference LED screen pages, or send us your wall size and source format and we will confirm the controller and the receiving-card plan.
