HDMI cables

finding the right set of HDMI cables can sometimes be pain so here is a short non-comprehensive overview of what is out there.

Ordinary HDMI cables. They used to be expensive, fortunately now there are plenty of cheapo cables around with still acceptable quality. These can come in various sizes from 0,5m to 20m and longer. For building a small video rig 0,5m is fine but going to a mixer or display that sits at another end of the room, 5m or 10m is better. The connectors are fairly large and the cable is stiff and not so great to work with if you need to bend it etc. These cables are usually remarkably strong and built to last. Sometimes they come with golden (?) contacts so maybe it makes a difference but probably not. Sometimes the cables are advertised as “high speed”, “4K” or “3D” and agin, maybe it makes a difference but probably not.

Flat HDMI cables. All the same as the ordinary ones but the profile of the cable is flat instead of round. Flat cables have an advantage if you want to tape it to the floor or going under the door (or under any other obstacle). They are still pretty stiff but somewhat less than the round ones.

Flexible HDMI cables. Same as the ordinary HDMI cable but with flexible (usually thinner) cable that can be bent and moulded when building a video rig.

Small connector HDMI cables. Sometimes they come with thinner and more flexible cable and when they do they probably are the most convenient for a smallish video setup.

90 degrees angle HDMI cables (up or down). Both connectors can have the same angle but can also have a different one and there is an option for only one connector to be at an angle. Can be come also with a flat cable. Good for getting the cable out of sight but only if you buy the one with the angle that matches your equipment. ETC and Eyesy are having their HDMI port reversed so check your connections before buying one.

90 degrees angle HDMI cable (left or right). Can be come also with a flat cable. Good for getting the cable out of sight but only if you buy the one with the connector angle that matches your equipment.

Ribbon cable HDMI cables both with a straight connector or with one (or both) connector at an angle up/down or left/right. These are made for specific usage like for drones, raspberry pi etc. These cables are lacking plastic protective layer and are fragile when compared with consumer cables. However, these are very flexible and can be used to build custom video systems but you have to know what you are doing.

Adaptor cables. Good way to connect different formats like mini HDMI to HDMI.

HDMI adaptors. Come in different angles and in different sizes. Don’t use one. If you do, it’s probably fine.
