All VIVIFY fiber optic HDMI cables have to pass two rounds of functionality tests before going to market. A functionality test is performed during the design verification stage with a second verification test done after mass production.


Source and Display testing during the design verification stage


Two devices are used to test the cable functionality. First, the video analyzer QD780 checks all the channels and signals, then a source and display device is used to verify the image result. The inspection list includes:

From the QD780:

  1. +5 Voltage: Affects the signal transmission.
  2. Different resolution signals: Affects the functionality on different resolutions.
  3. High speed channels：Affects the screen flicker or blackout.
  4. Low speed channels：Affects the hot plug function.
  5. Consumer Electronics Control(CEC): Allow users to command and control devices connected through HDMI by using only one remote control.
  6. Display Data Channel (DDC): This is used to read the E-EDID data from the HDMI sink device to learn what audio/video format it can handle.

From the Source and Display devices:

  1. Source and display testing: connect to the actual display and source, 5 minutes visual inspection for any abnormalities.

If any of the items in the inspection list fail, the cable is then marked as defective. The cable will then be investigated to find out the issue and fix the relevant design or process.
