Touch Screen Monitor,JOHNWILL 15.6 Inch Portable Touchscreen Monitor IPS LCD 1920x1080P Monitor HDMI/USB/Speaker for Raspberry Pi PS3 PS4 Xbox 360 Compatible PC Monitors

I tested it with a number of devices, including: the new Raspberry Pi4, my laptop, my old Samsung Galaxy S7, my son's iPad and an XBoxOne. All seemed to perform exceptionally well with the exception of my old S7 (screen mirroring seemed a bit laggy). But, not too concerned about the S7 because my main reason for purchasing this monitor was for the RPi4 and it worked admirably as it did with my laptop. The construction of the unit is solid, I expect it to last for several years. Seems like a great product and one I currently recommend! My video review will be available on Oct 1st on my YT channel 'wagnerstechtalk' if interested.
