DisplayLink uses an installed driver and the system CPU and GPU to convert graphics data on the system into data packets. The second and third displays will rely on the DisplayLink software. This requires no user driver installation. The HDMI or DisplayPort output uses Alternate Mode (Alt Mode), and as it is basically a pipeline directly to the system’s native GPU, it will behave just like if you hooked up a USB-C to HDMI dongle to your laptop. This entails making some adjustments in the Mac’s “Privacy” tab, but you are walked through it step by step. The most scary bit is when you need to enable “Screen Recording” to allow the DisplayLink Manager app to capture pixels and send them to your USB peripheral. Older versions did not support laptops’ closed-display/Clamshell mode, but 1.8.1 does support Clamshell mode if the MacBook is Intel-based running macOS 12 or if the MacBook is M1-based running macOS 11 or later. You may need to quit and restart DisplayLink Manager afterward. This can be found in System Preferences under Privacy in Security & Privacy navigate to Screen Recording in the list on the left, then tick the Screen Recording permission for DisplayLink Manager after unlocking the padlock using your admin password. The macOS requires the user to permit “Screen Recording” in order for DisplayLink devices to work properly. It can be managed via the DisplayLink icon in the Apple Menu bar. 1.8.1 is compatible with macOS Big Sur 11, Monterey 12 and Ventura 13. You’ll need to download the appropriate DisplayLink software from the dock manufacturer-full instructions later on.ĭisplayLink Manager Graphics Connectivity App v. DisplayLink USB-C docks or just USB-C docks require software drivers to enable data compression that make them almost as powerful as a Thunderbolt dock. This should work with most third-party docks, although some manufacturers, such as Caldigit, don’t recommend it.Ī whole new category of docks-many reviewed below-has appeared to solve the M1/M2/M3 Mac one-screen problem. You can use a combination of display technologies to get around the M1/M2/M3 MacBooks’ single-monitor limitation. Workaround #1: Install DisplayLink software drivers We also cover the basics of how to connect your Mac to an external monitor. But the M1 models of the MacBook Air and MacBook Pro lack an HDMI port and only support a single external display over Thunderbolt.Īpple doesn’t look like it will solve this problem for you-it would prefer you buy one of its more expensive laptops! We have this guide to monitors for M1 Macs and what you need to know before buying. While the M1, M2 or M3 MacBooks natively support just one monitor, the M1 and M2 Mac Mini does natively support up to two external monitors-one via the HDMI port and a second via USB-C. Apple states in the M1, M2 or M3 MacBook Air and MacBook Pro tech specs that they support only “one external display with up to 6K resolution at 60Hz”. Apple’s M1, M2 or M3 chips simply won’t allow it-at least natively. They received rave reviews for their speed improvements over Intel-based laptops, including here on Macworld.īut if your MacBook setup includes running more than one external display, you have a major problem. External displays: Big problem for M1 and M2 MacsĪpple’s Mac mini, MacBook Air, and 13-inch MacBook Pro were the first Macs to feature the Apple-designed M1 processor (CPU). Installing third-party software drivers leads to a slight risk that these might later be unsupported by future updates of the macOS, but the two drivers we recommend are recognized industry standards that we think will continue to be supported. USB graphics is a software-based technology that compresses the video signals from the computer to the monitor, enabling you to connect multiple external displays to your M1, M2 or M3 MacBook. The simplest solution is to get a USB graphics-enabled docking station or hub-and we’ve reviewed the best ones in this article.
