Review on ASUS ZenScreen MB16ACE Portable External 15.6" Monitor, Full HD 1920x1080, 60Hz Refresh Rate, Flicker-Free, Blue Light Filter, IPS Panel by Tyrone Brumfield

Very good product for the price. I use it along with my laptop for virtual board games and its very useful ping pong between apps. All you need to connect is a connection cable. If you want the screen to switch from landscape to portrait, all you have to do is download the extension as mentioned in the Revain description. You must have an application open on your desktop to turn pages, UT is really nice if you are reading a portrait pdf document. Image quality is decent. I have to lean a bit to get the best light, but it's definitely worth it. I had to invest in a separate tablet stand as the case only offers an unreliable viewing angle, but these options are quite cheap so it's still a good investment.
