I had been looking for a portable monitor with cheap price. The Lepow and Asus are not bad, but it is too expensive for me, so I decided to find out direct distributors of these things. some of those have the MOQ requirements, so i gave up on them. However, i found out a manufacturer who makes this things, and they starts to make its own brand called Viewshocker. you can check on their website, just Google viewshocker portable monitor. compared with other famous brand, it is cheaper while the quality is outstanding, the color gamut, resolution is find for me.
