Review on Portable Monitor BIGASUO Rechargeable Spearker 15.6", 1920X1080, 160Hz, B-157 by Gary Alexander

Very poor screen quality. I see very faint lines. It's hard to photograph, but you can see it. When connected to my Mac with a USB-C cable, my Mac tried to draw power from the battery in the device rather than the charger, so I went back to using an HDMI cable to avoid draining the battery . The device cannot be used in portrait mode without an additional stand. clay is garbage.
