NewerTech has introduced a new Display Adapter for Macs that lets users add an extra display. The adapter plugs into a USB 2.0 port, and supports displays via an HDMI, DVI, or VGA port. Multiple adapters can be used on one computer for adding an extra display, with Macs supporting up to four while Windows-based PCs can run up to six screens. The accessory is available now for $96 on OWC’s eShop.
