Test your HDMI® cables with the Monoprice HDMI® Tester 320 before making the connections and never connect a bad cable again!
Testing cables is as simple as plugging them into the tester. One end goes into the tester Master unit, while the other end connects to the Remote Terminator. Although the Remote Terminator is attached to the top of the Master unit for convenient storage, it can be easily removed if the ends of the cable cannot be brought to the same location.
The tester automatically turns on and tests the cable as soon as you plug it in. The LEDs will all illuminate if the cable is good and, if it is bad, the corresponding LED will fail to light up.
WARNING!!! Do not test live circuits as it could cause damage to the tester unit or personal injury.
Note: This product has a universal card packaging that is used for PIDs 8129, 8130, and 8131, with the individual model marked on the back. The front of the packaging includes functionality tags for all three testers combined. Therefore, the packaging erroneously indicates that this tester is capable of testing HDMI, Coax, and RJ12 cables, which it is not designed to do. For Coax, RJ45, and RJ12/11 testing, please use
