Looks like this person has a triple monitor setup, so that'd be either three DisplayPort/HDMI cables or a single DisplayPort cable if they can daisy chain them (only possible if these are all 1080p monitors). It is an appealing idea, though. I wish there were an easy thin client solution where everything from your actual computer just goes over cat6. Unfortunately cat6 can only handle about 10 Gbps, vs. a single DisplayPort 1.2 cable that handles 18 Gbps. Wouldn't work for multi-monitor 4k setups.

What is the main limitation for cables regarding transmission rates? Do we just need to move to fiber?

I was surprised recently looking into wifi options that apparently the new wifi 6 claims to handle 2400Mbps.

I assumed a wired connection would always trounce wireless (and I guess cat6 can do 4x that), but it seems like people are moving mostly to wireless setups. Is it solely because of the inconvenience of wiring things through a building?

The entire WiFi network can handle 2400Mbps.

While a 10Gbps CAT6 cable can handle a 10Gbps connection up and down stream per wire.

In short: 10Gbps CAT6 vs WiFi6 on "apples-to-apples" terms is 20Gbps (10Gbps per direction) vs WiFi 2.4Gbps.

Note that each additional CAT6 cable you add to the network increases your aggregate bandwidth by another 20Gbps (10Gbps duplex). A 8-port 10Gbps switch can be organizing 80Gbps duplex (80Gbps to, and from, every port), or 160Gbps in WiFi terms.

You still need to have multi gigabit switching and cabling to supply those WiFi6 points though!
