HDMI® Signal Tester

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 PID 8129 . For RJ45 testing only, use PID 8130.

HDMI cable tester

Pros: Nice concept

Cons: Instructions are almost non-existant ! Still don't know if tester will work with active cables (Redmere) and/or if tester is sensitive to directionality of Redmere cables.
OK for standard cables.

Great idea, but I can't tell if it's working the way it's supposed to on active cables (Redmere) ???

Thank you for your review. Keep in mind the HDMI signal tester will NOT work with Redmere. I hope this clarifies it for you. Thanks!

Awesome Tester

Pros: Small, Light, Bright LEDS.

Cons: The only reason I gave this a 9 instead of a 10 was because the unit was quite hard to separate into two pieces the first time. After the first time the tester comes apart fairly easily.

The best part is it is two separate pieces so the cable can already be installed. Most other testers you have to test both ends of the cable close together at the tester. This on separates for easy testing of installed cables. It works great!!
