PC Extended Screen Pro

More Crazy Multiscreen This product consists of three 15.6-inch 4K screens, a built-in battery, and a built-in stand. It folds up to the size of a briefcase for easy transport and weighs 3 kg (6.6 lbs). It's compatible with Macs and PCs.

The stand is height-adjustable, with the trade-off being that the lower you position the screens, the more the supporting arms intrude into your workspace.
