Hi to all,
I also own an HiBook Pro from GearBest.
I have no problems with screen, Windows activation is OK (even after full format – reinstall with Windows anniversary 1604).
Yes maybe the 2K resolution is too much for Atom x5, it slows down smoothness BUT you can easly change it in Windows settings for a Full HD mode (1920×1200). There is also a way to do it in Android (need ROOT and Resolution Changer app). Mine is set at 2K in Windows and 1080p in Android in order to play games like RealRacing 3 ?
HiBook Pro’s Full laminated screen is just wonderfull in comparaison of other model: you get better brightness, vivid colors and permits you outdoor use ! I did an outdoor test with HiBook Pro and Hi12 tablets, the results are uncomparable ! HiBook Pro wins ?
