6.3.1 Cables
Use the correct HDMI cable or HDMI-DVI conversion cable depending on the system configuration.
For analog audio, select or fabricate cables to match the connectors as needed.
For 4K format video, the maximum TMDS data rate (transmission speed) is 18 Gbps. If a high-speed HDMI
cable that supports up to 10.2 Gbps rate is used, video cannot be displayed stably. Select an appropriate
18 Gbps high-speed cable depending on the 4K format.
The maximum distance may change depending on cable type and characteristics of source and sink
devices.
