Review on NexiGo 2021 4K Portable Monitor Computer: Premium 15.6" Screen, Stunning 3840X2160P Resolution, PM4K15-AM02, HD Display by Travis Jarvis

I am testing for the first time. Can only be powered on with my 2017 Macbook Pro 13 USB C model. Can also be charged via USB which is great. But I don't like the rocker switch as it's finicky and I'm not sure my settings will stay after I set it up. It doesn't seem to be. I always seem to have to set it to my preferred settings before I'm happy with it, as the default brightness just washed out for me.
