Great portable monitor to move around with while working from home. Love the fact that you don't need multiple wires and it is powered by the same cable that connects video. Could be a reason you can't adjust the brightness. Overall its a good monitor for what I'm trying to accomplish although the one thing I would change is the ability to adjust the brightness.
"Working mostly on a Surface Book, this is an excellent addition! Having a second display (and one that is larger than my main screen) makes me more productive while working. Now, on to the review of this product: I purchased this after doing some research and reading reviews and this particular model, UPERFECT 15.6 Inch IPS HDR 1920X1080 FHD, looked like a good choice. The price was right and it seemed all inclusive. After receiving my order, the box it came in was actually nice; form fit and very similar to my Surface Book packaging. Inside were all the items and more. Everything was well labeled and easy to find. All the cords (HDMI to mini display, USB C to USB C, USB C to Mini USB -for power, power adapter, screen protector, carrying case and stand -even a squeegee to help put the screen protector on! After powering up, and plugging into my surface it worked brilliantly right away. So far, I'm very happy with this product and highly recommend it! "
