Review on Enhance Your Display Experience with the GMK Portable Monitor: Full HD, Freesync 60Hz, HDR, IPS by Rob Williams

I took it out of the box to connect to my Samsung Note 20 Ultra and the screen just flashed some crazy nonsense and went blank! Then I tried to connect to my PC and the same thing happened! So I will return this product for another one or refund the money if the second one doesn't work! Edit: After getting the same monitor and this one working I can see that it is doing its job very well! Everything you touch on the screen looks like you're touching the phone directly! Although I do wish the cables used for the monitor were a bit longer and it would be nice to add a screen protector as that would be a fingerprint magnet in everyday use.
