Comment on If you can't buy it, make it: EN25 corner that fits HDMI cables.

$300 per connection: 2 display connections and two USB connections would cost $1200.

Does this answer your question?
My solution isn’t cheap either: 10m USB-C 10gbit: 50€ each(b-stock/customer returns, normally expect to pay 100€), 15m DisplayPort & HDMI: 40€ each.
Total is approx. $200-2500 between cables and building materials.
And more often than not I find myself having to change one thing to wireless
Wireless HDMI is pretty interesting but low quality and high latency. The 60 GHz never took off and wouldn’t work anyway as it can’t pass through walls.
Wireless USB was a thing with USB 2.0 but it is dead. There was also some 60GHz USB for VR but that also failed in the market.

Ah, I’ve never looked into what hardware is actually available at the consumer level. That is a lot of money to move a video signal from one place to another.
FWIW I just looked at the AliExpress-tier options and they are much cheaper, but I don’t know about latency situation even if they do hit advertised bandwidth.
I didn’t even know HDMI cables went up to 15m for the copper version.

Those low cost Aliexpress hdmi over RJ45 are “last gen” HDMI limiting yourself to 4k@30Hz. This place already has CAT7 cabling so this would have been so much easier but sadly it isn’t good enough and the current gen are to expensive.
They are fiber optic with copper for power supply and side channel. For some reason they are fairly affordable compared to OM3 fiber solutions. Probably due to them running multiple fibers allowing the transceiver to be slower and simpler. With OM4 cables there is only one fiber per direction. I think HDMI is 4 pairs so it is 5GB/s for 4 fiber compared to 20GB/s for the OM4 cable.
I personally hate copper cables. There are so many bad cables out there that it can be hard to find one that works reliably (2-5m range). Knowing now that you can buy 5m fiber optic for 30€ I probably will move forward only buying fiber optic and just coil up the excess length.
