I'm currently waiting to get a Dell UltraSharp 27" 4K U2723QE delivered. It's
~$630 and has a USB 3.2 Gen2 Hub:
- HDMI 2.2
- DisplayPort 1.4 Input
- DisplayPort 1.4 Output
- USB-C Upstream (PD 90W + DP 1.4 Alt Mode)
- USB-C Upstream (KVM)
- USB-C Downstream
- 5x USB-A Downstream
- Audio line-out
- LAN (RJ-45)
As far as I can tell it has the best connectivity and specs of any mainstream consumer monitor under $1k. It really doesn't feel worth it to spend $250-400 on a dock given the price point of these monitors.
It also doesn't have a power brick, which makes cable management a bit easier too.
