HDMI cables are very common in today’s display industry. Computers, TVs, and some projectors even give HDMI capabilities. Being also capable of streaming sound through the cable, HDMI boasts a heavy way of sending heavy data.
It can stream at very high-quality resolutions and is most consistent when it comes to frame rate as well. Oh, and did you also know that HDMI can pass ethernet data using its own cable? Surely, using HDMI as your main display cable for home use is less daunting than other means!

How to test your HDMI cables
Testing HDMI cables is really easy and straightforward. There might be differences as per device, but in general, the procedures are the same.
A fully functional cable tester for HDMI
This is an example of a fully functional cable tester for HDMI, which can be used by homeowners and professionals alike. Housed in plastic, and can be detached from one another through hinges, giving it a portable and slick design. Easy storage? No problem, just detach them and put them over each other if you don’t have enough space.
Now, you may be able to see three ports. Two are for normal HDMIs (for input and output) and then the other is for HDMI Mini. There’s actually another port for output HDMI mini at the bottom of the smaller part of the device. The left side of the device (the larger part) checks for input, and the smaller part (the right side) checks for the output part. Why are there four ports instead of just two, you ask? That’s because with this device, not only you can test HDMI-to-HDMI connections, but also connections for mini HDMI!
It has a total of 20 lights per used port (20 on each side) which checks the wire connections for faulty issues like wrong circuits and crossed wires. Even for normal users, this just means that they’ll most likely get rid of the HDMI cable and buy a new one, professionals in displays and information technology will find it useful to check for errors and diagnosing devices.
For normal users though, do you want it to just be simple and not show you the unneeded details like there having issues with things like crossed wires on sectors 15/16 and such? Then you can just press the power button again on startup, and it will change modes; turning into a yes or no mode, where it just tells you if it works or not.
You just simply have to plug both ends of the cables into their ports, and you’re all good to go!
Now what you’ll need for the testers are, of course, a single 9-volt battery. This type of battery will last for hours of use and will probably live through dozens upon dozens of tests. Some tester devices shut off automatically if they aren’t used for ten to fifteen minutes though, so no worries if you accidentally forgot to shut it off!
When it’s time to install a new battery, the device will flash blue constantly, reminding you that its voltage is lower than normal and allowed. You can still use it though, but it will only last you a few tests probably.
Here are other examples of more compact testers, unlike the other one shown above, this can probably fit in your bag easily, or even your pockets. Don’t be fooled by its size though, it can still fix possibly any problem these wires will ever have under any normal circumstances!
Models like these show indicators through LED lights in the front part of the device, and unlike the other version only have two rows of indicators. This is definitely easier to read, especially for those who aren’t really looking for much details with their cables.

If you fancy more modern testers that are used by professionals because of more details, you can use these types of testers. Even finicky versions like HDMI 2.0 that have subtle problems are no match for these testers, which sense even the most unnoticeable problems your HDMI cable has! These more advanced testers also are rechargeable, unlike those previous versions that use batteries that have to be replaced each time.

How do I use HDMI testers?
Using these HDMI testers will follow the steps below:
- Turn the tester on by pressing the power button once.
- You simply have to plug an HDMI cable into both ports and it will go through the whole sequence of indicator lights.
- To know if the wiring is all correct, the lights on the first part of the device should also be the same as the right one (For example, light number 1 is lit up on the left side, the light number 1 should also be lit up in the right side).
- If there are any mismatches between these two, then there is most likely something wrong with the cables and it might need fixing or a replacement.
Is there a way to test HDMI cables?
The short answer is yes, testing HDMI cables is as easy as testing any other electrical cable. However, you need the right equipment.
Something as simple as using a multimeter will work, but something like that does not really show us details like data transmission or whatnot. It only shows us how much is going through and if it works. Basically, it only lets us know the very basic details like if it’s actually working, but there will be nothing said about the capability of transmitting a certain amount of data.
There are dedicated HDMI testers, though. From portable to bulky ones, you won’t run out of varieties too fast! Some have multiple HDMI versions compatible with them, while some are only dedicated to a certain type.
All you have to know is that testers have two main input ports, the output port, and the input port. You’ll just have to plug both sides in with the HDMI cable you’re testing, and you’re all good to go!
From testers to just knowing their types and capabilities, you will be able to get a good idea of what these cables are capable of. Not only that, you now know which type to pick for your next trip to the store!
However, be still on the lookout for bad products, especially from untrusted brands. Buying a cable because it’s cheaper might have consequences, and you’ll save a trip back into another store if you manage to pick the wrong one!
