Treedix Cable Tester Board for HDMI Cable Tester Checker 20 LED Light Status Indictor to Check Disorder Short Open and Cross Connection for Standard HDMI Type A, Mini HDMI Type C, Micro HDMI Type D

It's nice to be able to quickly assess the quality of cords and connectors -- and throw out the faulty ones.

Works well for me. In my experience, 90% of HDMI cable problems I've encountered are due to broken wires in the cable, with breaks typically being at or around one of the connectors or just past the strain relief where there may be a sharp bend or kink in the cable. This is a quick and cheap way to check for breaks in the cable, and because it runs a continuous continuity check, you can "wiggle" the cable to see if one or more connections open up when twisted. I like it better than an older HDMI cable tester I have, because it shows all the connections at once, rather than cycling through them one-by-one like the old tester. It offers mini and micro HDMI ports, so you can test those weird cables you get with some cameras and video devices. And, it has a lithium coin battery so it is portable, although it does have a USB power input as well (just remember to keep the power switch turned off when not in use). The only negative is that it is an open frame circuit board with a transparent shield over it, not a closed box, so you have to be careful and gentle in handling it. But given the cost, that is something I can live with. This is not something you use to test an HDMI cable to see if meets specific HDMI version transmission standards; it is simple "light box" to check for broken wires. It is very similar to the old RS-232 "breakout boxes" we used back in the day, without the wire jumpers.

It works, what more do you want? Used this to cull my cable pile a bit. Good for figuring out which actually have all the pins they're supposed to have. The polycarbonate shield and screws are sort of cheap, FYI.

Needed a HDMI tester after wiring up the HDMI cable to my son's room only to find it didn't work.... I have multiple electronic testing devices but not ONE to test HDMI cables. Received well packaged and I tested its operation on 30, 50 and 100ft HDMI cables without fail. Works for me! Love the ability to see where the connection fail has occurred in the cable. I have two different testers now and they both work well!

Great for troubleshooting when a HDMI cable is to blame for not receiving ATMOS audio.

Works as advertised and very versatile

We needed a small, reliable tester for HDMI cables at a reasonable price. This wasn't for a business, just occasional household use. The basic, no frills, little tester has been accurate in our small sample. It quickly identified both good and bad cables which saved time in troubleshooting faulty devices. We actually like the look of the exposed circuit board and simple design.

This tool answered a lot of questions for me. In the HDMI plug there are 20 connections, BUT there are only fifteen that make it from the plug on one end of a cable to the plug on the other for EVERY cable. That is to say that yes there are some cables that all twenty circuits work, but not all. I am using HDMI for an unconventional application and was hoping to utilize 16, or maybe all 20, no such luck for me. But, at least this tool took the mystery out of why it was not working.
