Acer's SpatialLabs division aims to bring a 3D stereoscopic experience back in a major way in 2022. To this end, it has brought this technology to portable monitors in the form of the View and View Pro. They are both 4K and weigh under 1.5kg (3.3lb); however, the Pro variant is pitched more strongly at enterprise use-cases with a retail-friendly design and support for popular rendering and editing programs.
