# UHD Quad Link config for AJA Kona 4

AJA cards need special handling when configured in QuadLink mode. Here's how to configure AJA Kona 4 to monitor UHD signal in QuadLink SDI configuration. 

We are going to be using DeckLink 8K Pro on sending side and AJA Kona 4 on receiving side.

### Wiring

Here's DeckLink port numbering:

### Configuring the sender

DeckLink connectors should be configured in SDI 1 to 4 In or Out way:

### Configuring the receiver

On the receiving end, configure AJA card using AJA ControlPanel to expect 4 SDI inputs in QuadLink configuration and make sure to check the QuadLink UHD option in the input settings in OmniScope:
