LED DISPLAY CONTROLLER FAQ

What is an LED Display Controller? How does it relate to a video processor?

The controller is the "brain" of the LED system. It receives video signals from a processor or PC and converts them into serial data that the LED pixels can recognize.

  • Relationship: While a video processor focuses on "optimizing and scaling the signal," the controller focuses on "distributing and driving the image." In the 2026 market, most devices are "All-in-One" Video Controllers that combine both functions.
What is the difference between "Synchronous" and "Asynchronous" control?
  • Synchronous Control: Displays content from a PC or media player in real-time with ultra-low latency. Ideal for live events and conferences.
  • Asynchronous Control:
    The controller has its own memory and OS (e.g., Android). Content is uploaded via Wi-Fi/4G/USB and played offline. Ideal for advertising signage and digital posters.
How is the loading capacity of an Ethernet port defined?

Theoretically, a standard 1G Ethernet port can carry up to 655,360 pixels.

  • Pro Tip: In practical engineering, it is recommended to leave a 10%-15% redundancy for stability. Most technicians calculate based on 550,000 to 600,000 pixels per port.
What are "Ultra-large Capacity" and "5G Transmission" in 2026?

By 2026, mainstream controllers have adopted 5G bandwidth transmission (5Gbps Ethernet ports, not 5G cellular). Compared to traditional 1G ports, a 5G port increases the loading capacity per cable by 5 times, significantly reducing the complexity of rear wiring for 4K/8K screens.

How does the controller support high refresh rates (e.g., 7680Hz)?

The refresh rate depends on the synergy between the controller, receiving cards, and driver ICs. The controller must provide sufficient processing bandwidth to ensure flicker-free visuals even at high brightness levels.

Why is the screen garbled or black after replacing a controller?
  1. Configuration Files (RCG/RCFG): Every LED module has specific driver parameters. You must send the correct "configuration file" to the receiving cards via control software.
  2. Connection Logic: Ensure the physical cabling order (Port 1, 2, 3...) matches the "Screen Connection" map in the software.
How do I fix a specific area of the screen that is not lighting up?
  • Check if the Ethernet port indicator light on the controller is flashing normally.
  • If an entire string is dark, it is usually a controller port or first receiving card failure. If only a few middle panels are dark, it is likely a damaged cascading Ethernet cable.
How do modern controllers achieve "Pixel-level Calibration"?

High-precision cameras capture the screen to identify brightness and color variances
in every pixel. The controller generates a coefficient map stored in the receiving cards. 2026-gen controllers support One-click Calibration Recovery, automatically applying parameters to new modules to ensure color uniformity.

How can I monitor the controller status remotely?

Most 2026 controllers support cloud-based management platforms (e.g., NovaStar VNNOX). Users can check screen temperature, smoke alarms, and even take real-time screenshots of the current playback via a smartphone.

LED VIDEO PROCESSOR FAQ

What is the primary role of an LED video processor?

It acts as the "translator" between signal sources (PC, camera, media player) and the LED display. Its main functions include:

  • Image Scaling: Scaling signals of various resolutions to match the pixel-to-pixel size of the LED screen.
  • Signal Conversion: Converting different formats (HDMI, DP, SDI, etc.) into a unified processing signal.
  • Image Enhancement: Performing color correction, noise reduction, and edge sharpening.
What is the difference between a processor and a Sending Card?

A Sending Card is responsible for packaging image data and transmitting it to the receiving cards via Ethernet cables. A Processor handles signal selection, scaling, and optimization. Most modern devices use an "All-in-One" design, where the sending card functionality is integrated into the processor.

What is "Loading Capacity" and how is it calculated?

Loading capacity refers to the maximum number of pixels a processor can drive.
Typically, a single Ethernet port carries about 650,000 pixels. To calculate, multiply the screen's width by its height; ensure the total pixels do not exceed the processor's maximum output (e.g., 1920×1080 = 2.07 million pixels).

Why is there a delay (latency) on my LED screen?

Latency usually comes from three sources: the signal source output, the processor's algorithm, and the sync process of the sending/receiving cards. High-performance processors supporting Low Latency Mode can reduce this delay to within 1 frame (approx. 16ms).

What does "Seamless Switching" mean?

It refers to the ability to switch between two input signals (e.g., switching from a PPT to a video) without the screen going black, blue, or flickering. It often involves transition effects like "Fade in/Fade out."

What should I do if the screen displays "No Signal"?
  1. Check physical connections (ensure HDMI/DP cables are secure).
  2. Verify if the signal source (PC) resolution exceeds the processor's supported input range.
  3. Manually switch the input source channel via the processor's menu.
How do I fix an incorrect aspect ratio (stretched or compressed image)?

Go to "Output Settings" or "Scaling Mode" in the processor menu. Choose "Full Screen" to automatically fill the display or "Pixel-to-Pixel" to maintain the original ratio (which may result in black bars).

Which core parameters should I focus on when buying a processor in 2026?
  • 4K/8K Support: Whether it supports 4K@60Hz or higher inputs.
  • HDR Support: Compatibility with HDR10 or HLG for enhanced contrast.
  • Multi-Window/Layering: Support for Picture-in-Picture (PIP) or multi-source splicing.
  • Control Protocols: Support for remote network control or integration with central control systems.

LED DISPLAYS FAQ

What is an LED display? How does it work?

An LED display is a large screen composed of multiple LED panels seamlessly joined together to form a complete video screen.It uses light-emitting diodes (LEDs) to produce bright, high-resolution images, making it ideal for various events, concerts, conferences, or outdoor advertising.

What events are suitable for LED displays?

LED displays are suitable for a wide range of events, including corporate presentations, trade shows, concerts, sporting events, weddings, festivals, and outdoor marketing campaigns.They provide a powerful visual impact, attracting large audiences.

How big can an LED display be?

LED displays can be customized in various sizes to meet your event needs.Whether you need a screen for a small gathering or a giant display for a large event, the size can be adjusted by adding or removing panels.Common sizes are 16 ft x 9 ft and 20 ft x 40 ft.Custom sizes are also available to suit your specific requirements.

Can LED walls be used both indoors and outdoors?

Yes, LED walls are versatile and can be used both indoors and outdoors.Outdoor LED walls are weather-resistant and can function normally under various lighting conditions, even in direct sunlight.

What is the resolution of my LED display?

The resolution of an LED display depends on the pixel pitch, which is the distance between the individual LED beads.The smaller the pixel pitch, the higher the resolution.We offer various pixel pitches to meet the different needs of your event.

How do I choose the right LED display size and resolution for my event?

Please consider factors such as viewing distance, venue size, and the type of content you want to display.The appropriate size and resolution will be determined based on your specific needs.

How much does an LED display cost?

The cost of an LED display depends on various factors, such as size, usage duration, and additional services such as installation and technical support.

How many power does an LED display require?

LED displays require a stable power supply, and the required power depends on the size of the display.

Can I display custom content on an LED screen?
