I use HDMI on my Smart TV and just disabled wifi because I realized it was downloading more than half my bandwidth (a small amount, in fact). It could have been doing an update but I found no reason to leave it on. Occasionally I'll use YT or Prime since it doesn't have to be tethered to a PC, but overall it's nicer as a monitor than a streaming app.

Not that I believe it is used, but an ethernet connection can actually ride over HDMI. Possible to share your network connection by plugging in a display.

I believe that was eventually dropped from the standard due to disuse, but I might be mistaken.

I am curious if PoE (Power over ethernet) ever worked on HDMI. I know there is some minimal data sent, but would be hesitant to leave an HDMI cable plugged in if it has any Ethernet or power capabilities. I wouldn't be surprised the feature was dropped due to general security concerns (not that it's a useless feature- in fact I would prefer that in some cases, although newer monitors can also be powered by USB-C, negating some of that need.
