Lenovo - M14d (63AAUAR6US)

My portable setup: Lenovo ThinkVision 14 inch Portable Monitor - M14d. It has a 16:10 aspect ratio Stand from Amazon https://a.co/d/3juUy8n

I have a Thinkvision M14 which I bought for Work trips but used it in the past as a secondary monitor. My main issue was that it was too small or too far down for my liking so I opted to not use it for that anymore. Maybe with a 16" or larger model this wouldn't be too much of an issue. Also 50$ at Amazon doesn't sound like its a very good display tbh. If you invested in a G9 you probably should match it with something nicer

I have one of those thinkvision displays (the M14 to be specific) and it works with basically everything using a bidirectional USB-C to Display Port Cable. You just need to supply power separateley. If you try to use just USB-C it probably does not carry a video stream. You can check whats supported by the Logo above the port on your PC

I use a ThinkVision M14 with my SGo3 (and other devices) without any issues.

I hate trackpads with a passion. So my mobile setup is either the Thinkvision M14 with a Apple wireless BT keyboard and Logitech MX Anywhere 2, or a Thinkpad Compact USB keyboard with integrated trackpoint (unfortunately this keyboard is too fragile to lug around without a hard shell to protect the keys).
