Review on Take Your Productivity Anywhere with the Portable INNOCN Touchscreen Monitor - 15.6" HD, USB-C & HDMI Connectivity, Built-In Speakers". by Steve Brodhacker

So disappointed! Despite connecting a USB-A to USB-C cable and an HDMI cable, the touchscreen does not work with a 2021 MacBook Pro (14-inch). It works with my Samsung Galaxy ZFold 2 and the picture quality is great! The sound is minimal and not big, but acceptable. With all the cables and adapters needed to connect everything to my Macbook, it was a mess. I could live with that if the touchscreen worked with my Macbook.
