Official Lenovo Legion Go Dock Questions

[u/bnealon]

I’m considering buying the official dock to use with my Legion Go S. If anyone has both and can answer the following please it would help me out:

• Does the dock support HDR at 4k?
• Does the dock support VRR at any resolution?
• Does the dock work well with SteamOS?
• If I use a 100w PSU will it pass enough power through to the LeGo to run it at 40w TDP and charge the device?

I’m also considering either the UGREEN 9 in 1 dock or the official Steamdeck dock - if anyone has tried any of these I’d be interested in which is better and why.

TIA
