Overview Kystar KSV8c 2-in-1 Controller supports 3-channel digital signal input and features 8 network port outputs, with a maximum load capacity of 5.2 million pixels. Adopting a pure hardware FPGA architecture, it enables 365×24 hours of continuous operation, fully meeting the configuration requirements of large-screen control systems for small-pitch applications. Features - Equipped with 8 network ports in a standalone unit, each supporting up to 65K pixels. The entire unit can load a maximum of 520K pixels, with a maximum resolution of 8180×4090 pixels. - Supports multiple digital signal interfaces, including 1 HDMI 1.3, 1 DVI-D, and 1 HDMI 1.4 input. - Enables three-screen display with arbitrary layout configuration. - Supports flexible cable routing; network port load is not restricted by rectangular boundaries, significantly improving network port utilization. - Outputs test patterns such as solid color, gradient, and scan line, facilitating on-site debugging and testing. - EDID configuration management: Supports reading, modifying, and customizing EDID (Extended Display Identification Data). - Features one-click black screen/freeze function for quick operation. - Border removal/cropping: Eliminates black borders generated by front-end signals and allows arbitrary cropping of any signal source while maintaining full-screen display. - Supports key lock to prevent accidental operations. The brightness and contrast of the overall output image can be adjusted quickly and in real time.

LED displays are now very well-known and widely used with audiences engaging on big screens in stadiums, billboards, and sometimes, street art. But, there appears to be a myriad of parts that are clustered together for it to work in unison. One of these components which is the sending card has in the past been crucial in the running of the LED screen. However, with advancements in technology, the question arises is a sending card always necessary?

The Sending Card: A Crucial “Translator”

In most LED displays, the sending cards act as a bridge between the content source (like a computer) and the LED screen itself. It receives the video signal (HDMI, DIV, etc.) and translates it into a format the screen can understand. This involves processing the data, splitting it into individual pixel information, and synchronizing the output to ensure a clear and cohesive image on the screen.

Advantages of Streamlining the System

Companies like Kystar, a leading innovator in LED technology, are pursuing the boundaries by developing systems that can potentially eliminate the need for dedicated sending cards. Through advancements in computer processing power and software optimization, these systems can handle the conversion task directly within the computer itself. This can offer several advantages:

SimplifiedSetup: Eliminating the sending card reduces one component in the system, streamlining the setup process for users.

CostReduction: By removing the need for a separate hardware component, the overall cost of the LED display system can potentially decrease.

EnhancedFlexibility: Integrating the sending function into the computer allows for greater flexibility in terms of content management and display options.

When is a Sending Card Still Relevent?

While the potential to bypass sending cards exists, their role remains valuable in certain scenarios.  Here is when a sending card might still be the preferred choice:

ComplexDisplays: For intricate LED setups with high-resolution screens or multiple connected panels, a dedicated sending card can offer better processing power and ensure smooth, synchronized visuals.

LegacySystems: For existing LED displays that rely on older technology, a sending card might be necessary for proper compatibility and functioning.

Advancedfeatures: Some sending cards offer advanced features like scaling, colour correction, and scheduling functionalities, which might not be readily available through a computer alone.
