RGBlink D4 modular 4K video processor
The RGBlink D4 scales and switches video for LED screen and presentation systems. Its dual-channel 4K output scalers use 12-bit processing with internal YUV 4:4:4 color processing. Modular inputs accommodate different source connections, while standard HDMI 2.0 outputs and an optional DisplayPort module provide output choices.
Output formats and screen splicing
D4 supports 4K at 60Hz on compatible HDMI and DisplayPort outputs, plus output splicing up to 8K2K. These describe different operating arrangements: a spliced canvas is not the same as a single 8K2K output connector. Select the output mode and timing for the connected display system.

Frequently asked questions
Does the RGBlink D4 output 4K at 60Hz?
Yes. The specification lists 4K at 60Hz for HDMI 2.0 and DisplayPort 1.2 output configurations. DisplayPort requires the appropriate optional module.
What does 8K2K splicing mean on D4?
It describes the supported combined output-splicing arrangement. Check each output timing and the intended screen layout separately; it does not mean every connector provides one 8K2K signal.
Are SDI inputs built into every D4?
SDI is a module option. Choose the required 3G SDI or 12G SDI configuration when specifying the processor.
Does D4 support HDR and EDID management?
Yes. HDR signal support and EDID management are listed features. Confirm source and display compatibility for the complete signal path.
Where can I find the D4 connector and timing specifications?
Use the original D4 specification PDF below. It lists module choices, connectors and supported input/output resolutions.
