To determine the version of your HDMI cable, you can follow these methods:

Check the Text on the Cable: Examine the text printed on the cable itself. Some HDMI cables indicate their version directly on the cable body.

Inspect the Packaging or Receipt: Look at the packaging the cable came in or check your purchase receipt. Sometimes, the cable version is mentioned there.

Test with Display Devices:

1. Connect the HDMI cable to your computer or TV.
2. Adjust the display settings:
3. Set the resolution to 4K.
4. Set the refresh rate to 60 Hz.
5. Set the color format to full RGB.

If the cable can handle these settings, it’s likely an HDMI 2.0 cable. Otherwise, it might be an HDMI 1.4 cable.

Remember that the HDMI interface version (found on input/output ports) is different from the HDMI cable version. The interface version determines the capabilities of your video connectivity, while the cable quality affects performance standards. So, check both aspects to ensure optimal performance!
