macOS Mojave fixes problems with DisplayLink multiple monitor drivers

The ability to connect multiple extended DisplayLink monitors is fully functional in macOS Mojave after being impossible in later versions of macOS High Sierra, the creator of the format has confirmed.

The technology has been working in Mojave betas since July 30, DisplayLink said. The company is currently testing a beta of its v5.0 Mac software, and says it plans to release the finished version when Mojave ships on Sept. 24.

The release of macOS 10.13.4 in April broke multi-monitor setups based on DisplayLink, causing screens to go black. The problem has persisted through 10.13.6, even though secondary features like sound and Ethernet should work.

In the interim DisplayLink has encouraged people to use its v4.3 software, which has a workaround enabling a single extended display.

DisplayLink has become a fundamental technology in the computer industry, used in some USB-connected monitors, docks, and other adapters. It lets people output video over USB, instead of having to rely exclusively on formats like HDMI and DisplayPort.

DisplayLink has no relation to alternate modes in the USB-C protocol allowing for HDMI and DisplayPort connectivity, or video-out ports in Thunderbolt 3 docks.
