Review on PON-B15 Portable Computer Protector - 15.6" Waterproof, Frameless, Tilt Adjustment, Built-In Speakers, IPS with 60Hz Refresh Rate by Akira Givens

I bought this monitor in May 2021 to help work from home and it has been great. I was very pleased. In December 2021 it stopped working. It clearly has power, green lights are on next to the ports but the screen stays black. I haven't found any useful information on online tech forums to explain what's going on. I didn't have insurance on it, so I'm stuck with duds. I gave it two stars for how good it was for 7 months.
