I've never actually looked into this so maybe this is a dumb question but how hard would it be to make a symmetrical HDMI cable with no "up" or "down"? USB-C was rightfully lauded for this but I personally have a much more frustrating history reaching around the back of tvs with an upside down HDMI cable.

Iirc hdmi has 19 wires. USB c is around 10 (but mirrored so ~20 on the connector). Making hdmi symetrical would require a 38 wire connector which would be large and prohibitively expensive.

USB-C uses 24 pins if you use the same criteria you're using for HDMI. Making HDMI symmetrical would be simple, albeit a connector redesign. USB-C already has the same high speed pins that HDMI does in a method that allows for symmetry.

The easiest to connect is the RCA connector. You can insert it at any rotation. With concentric rings it could provide more connections but it couldn't be as thin as USB-C.

It would probably also be a noisy connector.

How do you do the locking mechanism? I'm guessing that's why they're oriented

Where have you seen an HDMI locking mechanism? DisplayPort cables have the tabs, but I've never seen one on HDMI.
