Thank you for choosing RGBlink D8.
This manual provides information on the device features, installation and operation.
Before using the device for the first time, please read this manual carefully to ensure safe and proper use of the product.
The maximum standard input resolution officially supported by the D8 and D8 Plus is 7680 × 4320@60 Hz.
Both models support stable transmission of standard audio and video signals at this resolution.
D8 and D8plus supports 8K EDID management.
For HDMI 2.1 comes from Windows based PC or server, 8K EDID management with horizontal beyond 7680 pixels or verticle beyond 3840 pixels is achievable based on the graphic card we recommend.
For HDMI 2.1 comes from macOS based PC or server, 8K EDID management with horizontal beyond 7680 pixels or verticle beyond 3840 pixels is not recommend.
As the signal is not stable from HDMI 2.1 input. In this kind of application, DP 1.4 with D8plus version is recommend.
If the custom resolution signal is still not recognized after testing both input interfaces, contact RGBlink Technical Support for assistance with further troubleshooting.
Due to hardware limitations, the devices are not guaranteed to support all arbitrary custom input resolutions. Actual compatibility depends on the device's hardware capabilities.
The RGBlink D Series is designed to deliver high-performance video processing for professional AV applications.
As the flagship 8K video processor in the D Series, the D8 supports signal processing up to 8K@60, providing exceptional image quality and reliable performance for large-scale LED displays, professional presentations, and premium audiovisual installations.
The D8 features two HDMI 2.1 input ports as standard, while the D8 PLUS offers one DP 1.4 input and one HDMI 2.1 input. Both models are equipped with four HDMI 2.0 outputs, enabling 8K signal processing and flexible multi-display deployment. A built-in 4-inch LCD touchscreen provides intuitive device control and real-time status monitoring.
