Review on EVICIV Portable External Computer Freesync Speakers: 16.5" 1920X1080 EV15602 HDMI - Enhanced Audio for Ultimate Computing Experience by Shane Chapa

I just ordered the second one. Image quality is good, as befits a 4K resolution, but the brightness and color balance leave a lot to be desired. Playing around with the settings (which is a little painful) gives good results but still doesn't match my Dell XPS 4K screen or my spouses Air 4K screen. Or of course he is more, but still. This is a good monitor to use as a second monitor. I found the USB-c ports on these models to be better than some of the competition - as one would hope, they can source or transmit power and handle video.
