JOHNWILL Portable IPS Monitor Full HD Screen 1920 x 1080 Monitor Portable Ultra Thin Black CNC Metal Shell HDMI/USB Speaker Built-in, Raspberry Pi PS4 Display Gaming Monitor PC Monitors (15.6" CNC)

I needed a compact monitor for my portable video streaming desk, this works well, provides audio monitoring from the headphone socket (with an headphone amp added as it's not very loud), uses USB power and gives a decent picture.Not idea outdoors with the bright sky to contend with but at least the matt screen does not show strong reflections. I would probably have to pay three times as much for a better unit.The main reason I bought this model is that some of these screens can't handle different frame rates, this one says it's good for many uses so I assumed it would and it's fine with 60fps, 50fps, 30fps etc.

Got a refund, the 12 volt power supply plug had a plastic earth pin and didn't work. I also found to my dismay that the plug couldn't possibly fit in the cardboard packaging without breaking, never mind survive the June from China, the Country of manufacture. Amazon refunded my purchase so nothing lost fortunately. I would recommend you choose a different make.

I needed a monitor mainly for writing code that was sharp , non reflective, lightweight, easy on the eyes and that I could power just by using my portable power bank. Well this monitor checks all those boxes. Very happy!
