Review on UPERFECT Portable 4K UHD Brightness FreeSync 15.6" Monitor, Frameless, Built-In Speakers, Glossy Screen, Model: MDS-156A23, HD by Paul Brooks

I like the fact that the picture quality is very sharp, which is definitely not bad for its price (for a 15-inch 4K portable display). For gaming it's decent, I won't complain. I have two points that seem to contradict this - #1. The default display is a bit yellowish (but you can fix that with a little fiddling). I have another 17.3 inch portable display from UPerfect, it has a solid metal stand which I liked, but this one comes with a thin faux leather case that takes a bit of effort to get it at a good viewing angle (looks like one of the other cheap monitors). I only wish they would keep the built-in metal stand as well as their 17.3 inch 1080p monitor. This one is more solid, but the screen doesn't have a yellow tint by default.
