The KYY X90G adds three portable screens to your laptop but has major portability limitations

Los Angeles: The KYY X90G is a portable monitor that adds three extra screens to your laptop. It has one screen that folds out to the left one to the right and one on top. Your laptop sits in the middle giving you four screens total.
When fully opened the device stretches nearly 46 inches wide and weighs 6.4 pounds. This makes it too big and heavy for true portability. The screens need lots of power up to 30 watts so you will need extra cables and a power outlet. Three USB-C cables are provided but this is not practical for coffee shops or travel.
Each screen has its own buttons to control brightness color and position. The default brightness was too low but you can make it brighter in the menu. Setting up the screens with Windows is simple through the display settings panel. You can arrange the three extra screens around your laptop screen.
The main problem is the screen resolution. Each screen only has 1080p resolution which means icons and text look very large. This limits how much work you can do on each screen. More pixels are needed to make the extra screens really useful for work tasks. For casual use though the screens work fine but serious workers will want higher resolution.
