Troubleshooting
No signal on the display
Ensure both ends are firmly plugged into the HDMI ports and check that the correct source/input is selected on your TV or monitor.
Refresh rate capped at 60Hz
Verify that your graphics card and monitor both support HDMI 2.1 and that the display's 'HDMI Input Mode' is set to 2.1 or 'Enhanced' in the settings menu.
Audio not playing via soundbar
Confirm that your TV and soundbar are connected via the designated eARC ports and that eARC is enabled in the TV sound settings.

Setup, Compatibility & Care
To ensure peak performance, simply insert the connector into the designated HDMI port on both your source device (e.g., PS5, Xbox Series X, or GPU) and your output device (e.g., 4K/8K TV or gaming monitor). Because this is an active-capable high-speed cable, ensure both ends are firmly seated in the ports. When routing the cable, avoid sharp bends or heavy crimping, as this can degrade the internal shielding. Clean the connectors occasionally with a dry, lint-free cloth if dust accumulates, but avoid using liquid cleaners or abrasive materials. If you are not seeing 8K or 144Hz output, verify that your display settings are set to 'Enhanced' or 'HDMI 2.1' mode in the device menu.
