Review on 🖥️ StarTech.com USB 3.0 Dual DisplayPort Adapter 4K 60Hz, DisplayLink Certified Video Converter with External Graphics Card - Mac & PC (USB32DP24K60) by Laurie Thomas

I have decided to return this adapter. While it gets the job done, it doesn't support screen rotation, and as a developer I prefer to keep my left monitor in portrait mode rather than landscape. This adapter and macOS on the M1 MacBook Air do not give you this option. Also, the resolution options are limited, so this adapter is definitely not the same as using a direct-connected monitor. Also, some noticeable compression/video artifacts were noticeable. While this allows you to use your Mac m1 with multiple monitors, it is not the same as supporting the built-in external display. I agree, it just doesn't work for me as I need portrait/rotation support.
