Edit : For wired connections such as videos, or anything that needs a high bandwidth
In: Technology
Ethernet has pretty good bandwidth and pretty good speed which is fine for networking but not helpful for many other tasks.
Cat6 cable supports 10 Gigabit Ethernet over a distance of 100 meters which seems pretty good until you start comparing it to other standards.
HDMI 2.1 will handle 48 Gbps over a much shorter distance, and Display Port 1.4 can do 26 Gbps. These bandwidths are needed for displays as 4k 60 Hz video is a minimum of 12 Gbps and could be higher with HDR.
Coax cable was good for cable tv back in the day because while it has less bandwidth than we’ve squeaked out of ethernet today, it could run for hundreds of meters without a signal booster which was great for running it down streets on telephone poles
