Review on Eyoyo Touchscreen 1920X1080 Compatible Smartphone 13.3" - Portable, HDMI, IPS, 60Hz - UAEHLXZB0655YG by Thach Leighton

Finally found the perfect monitor for my Samsung Note 9. It can charge my phone via the USB port and the monitor itself can be easily powered with a separate USB cable. The touch screen just worked. Nice. Works well as a drawing pad for Autodesk Sketchbook. The speakers work and sound decent, but not very loud. The unit appears to be very well built and comes with a very nice gray "denim" textured cover that screws onto the monitor with thumbscrews. If you remove the thumbscrews, the monitor will have VESA mounting holes. It comes with all the necessary cables. One improvement I would suggest is that the small steering wheel is a little touchy. It's hard to press because it's so small, but once everything's set up you can only use it to adjust the volume, which works well. Also, the manual speaks of some kind of touch calibration that doesn't seem to be implemented or possibly unavailable with the original Android device.
