Long run of HDMI required for 4K

[Jac Hawk]

What does the HDMI spec say about cable length?

It usually gives a max length that a cable (meeting the spec) will support the signal.
I've not looked at the specs for a while, a few years back, I tried a 12m run that failed, when I checked the HDMI spec for the cable, it said max 10m in ideal conditions. People were selling terminated 30m lengths of this cable at the time, which was pointless.


Just check the relevant HDMI spec before you buy anything.

I work for a pro A/V company, we obviously use the correct cable for the job and wouldn't go over 10m on HDMI especially if you plan on transmitting 4K, we would use an Extron DTP HDMI 4K 230 Tx and a DTP HDMI 4K 230 Rx https://www.extron.com/product/produ...d=dtphdmi230tx, you use CAT5 cable to bridge the gap, simples.
