LED screens do not function alone. They need components and equipment to achieve their functions and maximum features. Some of the parts you will need is an LED display controller. 

There are various LED controllers you’ll see in the market; however, this equipment is designed with sole purposes and for designated LED screen types. That’s why to ease and shorten your finding time, let us give you some ideas.

The MCTRL 4K is an LED screen controller developed by Novastar. It is commonly used as an XR LED display solution; however, you can also apply it for fixed and rental installations. The device works compatibly with low pixel-pitched LED screens ranging from P1 to P2.9. 

Its technical features, appearance, and parameters are below. Should you have questions, please don’t hesitate to contact us or email us at


  1. What Is The MCTRL 4K?

The MCTRL 4k is an LED display controller developed by Novastar. It is equipped with an ultra-large loading capacity in which a single unit has a loading capacity of 4096 2160 @ 60 Hz. 

It comes with many industry-leading technologies, including HDR, individual gamma adjustment for RGB, 3D, chroma calibration, pixel-level brightness, and low latency. 

The MCTRL 4K LED screen controller is a robust, reliable, and stable product you can use. Also, it provides you with the ultimate visual clarity and experience and supports custom resolutions with a height or width of up to 7680 pixels. 

Furthermore, it is a typical solution for XR LED screens, a newly introduced technology for film and movies; however, you can also apply it for rental and fixed installation uses. 

  1. What Are Its Certifications?

The MCTRL 4K LED screen processor is certified with FCC, CE, EAC, UL&CUL, IC, CB, RCM, and KC. Certifications, such as the mentioned, may vary from country to country, therefore, if there are any required certifications before you can avail the product, please contact us immediately. 

  1. What Are Its Features?

  • Various Input Connectors

The MCTRL 4K LED processor has the following input connectors; 1 DP1.2, 1 HDMI2.0, and 2 DL-DVI.

  • Numerous Ethernet Ports

Each unit has 16 Neutrik Gigabit Ethernet ports and four optical ports. It also has a maximum output height and width of 7680 pixels. It also has high bit-depth inputs such as 8, 10, and 12. Here are also some things you can note; 

  • The DP/HDMI input has a maximum loading capacity of 8.8 million pixels.
  • The DVI input has a maximum loading capacity of 8.3 million pixels. 
  • HDR

The MCTRL 4K supports HDR10 and HLG and can compatibly work with receiving cards that also support HDR. These significantly enhance the image quality making it ultra-clear and with the best details. 

  • 3D

It can work with the 3D emitter EMT200 and 3D glasses. The 3D emitter and 3D glasses allow you to achieve 3D display effects on your device. 

  • Gamma Adjustment

This function adjusts the red, green, and blue gammas to control the image effectively. It creates uniformity in low grayscale conditions and white balance offset. This results in more prominent and quality content or appearance. However, it only applies to 10-bit and 12-bit inputs. 

  • Low Latency

Lower latency means minimal delay times. Hence, if you enable low latency and the input source sync, it can significantly reduce the delay between the receiving card and the input source. 

  • RGB Limited To RGB Full

RGB limited to RGB full happens when the color range of the input source converts the function to display natural black in low grayscale images. 

  • Chroma Calibration

This feature ensures that chroma and your device’s brightness are consistent. The calibration system removes brightness and chroma differences so the device can show up in a uniform visual. 

  • High-resolution Input

The MCTRL 4K LED screen processor supports settings for ultra-high resolution using an NVIDIA graphics card. The NVIDIA graphics card integrates AI technology and real-time functions. 

  • Easy Cascading

Cascading is connecting numerous units to perform a uniform function. The MCTRL 4K can be cascaded over up to 10 teams. So, if you have a massive screen for a big event, you don’t have to worry about graphics, refresh rate, and image clarity. Also, configuring screens, uploading, and you can do other functions on the web.
