Actually not a bad idea. Ethernet speed is one gigabit per second. And there are high throughput devices like LIDARs (eg Velodyne LiDAR known from Google/Waymo self-driving cars) that are connected via Ethernet rather than USB. Having 1 GBit Ethernet LAN network since 2004, I would prefer the possibility to upgrade to 10Gbit home Ethernet in near future.

It's a terrible idea. USB-3 is faster than 1Gbit/s. and there's no way you can drive a 5K monitor with any current or near future Ethernet standard, the bandwidth demands are too punishing. Ethernet isn't optimized around short-haul signals, like computer to screen over a few metres at most, it's for 100m+ runs in datacentres. The signals have to be a lot more durable.

    You can do more than that if the run is rather short. Cat6 is used on the 20Gbit cross-links on many stackable rack-mounted switches.

    Still not as fast as USB-3+Thunderbolt which is already 40Gbit/s and intended to be pushed to at least 80Gbit/s to support 8K screens.

  > there's no way you can drive a 5K monitor with any current or near future Ethernet standard, the bandwidth demands are too punishing. Really? You need more than 100gbit for 5k monitor? Because there is an 40/100gbit ethernet phy standard right now (has been for a while, since 2011). And work is being done on up to 200gbit (due to be ratified in late 2018).

  "and there's no way you can drive a 5K monitor with any current or near future Ethernet standard" That's an outright lie. 20gbit switches (like the one sitting in my living room) most certainly have the bandwidth.

  5120 * 2880 * 32bits * 60FPS is only 28.3 Gbit and both 40Gbit and 100Gbit are well established standards. Granted 40GB cards are running 50$ and 100Gbit cards are running ~700$, but that's most from the low volumes involved. Really though the larger issue is Ethernet connectors are not designed to be plugged in and removed regularly.

    > "Ethernet connectors are not designed to be plugged in and removed regularly" Well could easily use a smaller and easier plug while still being pin compatible with ethernet.
