With so many China brands out there does anyone know where u can find a certified list of long distance cables? Hdmi 2.1 cable.

It's by certified bandwidth, not a vague hardware spec.

Rather than a list of cables meeting that specification as new OEMs come and go frequently, just go for the App.

To verify the cable has been tested and certified in compliance with the HDMI 2.1a Specification, the label can be scanned by the HDMI Cable Certification app available on the Apple App Store, Google Play Store and other Android app stores.

I used to have it on my iPhone and it works well.

Read more about it here Ultra High Speed HDMI Cable Certification Program

It basically states the Ultra High Speed HDMI Certification Program is a mandatory certification program for all Ultra High Speed HDMI Cables. So the packaging has to display the certification label on it prominently. You can first look at the packaging and if it doesn't have the certification label on it, then don't bother going any further - even if you don't have the App. When I was looking for new HDMI cables, that's what I did. Then I'd scan it just to make certain it wasn't a bogus label.

By the way, just how long a cable are you looking for?

50ft length. Thx states that the 50ft plus length has not been passed other than there's with pixelgen.

At 50 feet, I wouldn't be looking at a passive cable as I've never seen one pass spec at that length.

For long cables you have to use a hybrid optical cable. The video goes via optical and the audio via copper. Ruipro are a good example of a quality cable.

These cables need a converter at each end, so they are directional. None of these cables are certified, as they all draw too much current from the HDMI board and are ALL out of spec. So you need to use a voltage inserter with these cables so that you don't blow up the HDMI board.

If you need a cable longer than 12 ft. then you should be using a hybrid active cable and none of them can be certified.

That is just one of of many daft situations that HDMI with its HDCP specs causes to happen.

I have been using a 35' Ruipro hybrid HDMI cable with voltage inserter for four and a half years without issue.

If you have a cable that length make sure you place it in conduit, or you will be very sorry.

There are also various HDMI Extenders for UltraHD running over a single Cat6/Cat7 cable available. I have no experience with them, and you'd have to make certain it is to the Specs you are looking for. I even saw one for USB-C. Interesting solutions.

I think you have to be very careful achieving HDMI 2.1 with extenders and Cat 6 or 7. There can be degradation and latency issues apparently.

When all is said and done, you will now save money when you buy very high grade extenders. The simplest and best solution is to use hybrid HDMI cables.
