KYY is counting the MacBook’s built-in screen in its quad lineup. The three it adds are larger than most we’ve seen of this type, with 15.6-inch screens larger than most MacBook screens, with the exception of the mighty 16-inch MacBook Pro.
The maximum resolution of each is 1920 x 1080 pixels (aka 1080p or Full HD) so some way off even the MacBook Neo’s 2408 x 1506 pixels, but still offering decent supplementary working spaces.

The screens fold up into a tidy but not insubstantial package measuring 15.4 x 8.9 x 1.3 inches (390 x 226 x 34mm) and weighing a hefty 6.4lbs (2.9kg).
In comparison, the two QHD-screen Mobile Pixels Trio 3 Pro measures 13.4 x 8.8 x 0.9 inches (34 x 22.4 x 2.3cm) folded up and weighs a more portable 4.13lbs (1.9kg). That makes it more carriable, but its 14-inch screens are smaller and fewer than what you get with the X90G.

Due to its collapsible form the X90G is a portable display, but it’s not an easy carry in your backpack. It’s fine for carrying between rooms or transporting by any means not on foot, which will suit you if you want to pack up your working space at the end of a working day or taking it on a long one-destination trip away from the office.
Hot-deskers with lockable cupboard space will find the X90G a handy display solution. If you prefer something more traditional, look to the larger but lower-footprint UPerfect Delta Max or Delta Mega that stack two screens on top of each other and fold away when you want a clear desk.
