USB to DisplayPort Adapter - Add External Displays up to 2560x1440

In this review of the Plugable USB to DisplayPort Adapter, the bottom line is simple: this adapter is for anyone who needs to add extra DisplayPort monitors to a Mac, Windows, or ChromeOS system without a native multidisplay TypeC Alt Mode. The adapter's hybrid 2in1 cable makes it easy to connect to either a USB 3.0 Type A port or a TypeC port, and it supports up to 2560x1440 at 60Hz, so it restores multimonitor workflows on modern M1, M2 and M3 Macs and works with many docks and Thunderbolt ports.

Key Features

• Hybrid 2in1 cable: lets the adapter connect to either a USB 3.0 Type A or a TypeC port so it fits laptops, desktops, and docking stations without extra cables.
• High resolution output: supports up to 2560x1440 at 60Hz so you get sharp, smooth text and sufficient desktop space for productivity tasks.
• Broad compatibility: works with Windows 10/11, macOS 10.14 or later, and ChromeOS 100.x or later when the required SMI driver is installed.
• Works without Alt Mode: functions even if the TypeC port lacks USBC Alt Mode, which lets you attach a DisplayPort monitor to devices that otherwise would be limited to one external screen.
• Scalable multimonitor setups: Windows and ChromeOS users can use multiple adapters with a dock to add several 1440p displays for expanded workspaces.

Who It's For

The adapter is aimed at professionals and power users who need extra screen real estate for spreadsheets, video calls, coding, and general multitasking and who may own Mac systems (including M1, M2, M3) that are restricted to a single external monitor. It is also useful for Windows and ChromeOS users who want an easy way to add a DisplayPort monitor without replacing docks or ports.

Users who need HDCP playback for streaming services should look elsewhere because the device does not support playback of HDCPprotected content like Netflix or Hulu. Also, users who expect plugandplay without installing any drivers should note that an SMI driver is required for operation.

Pros & Cons

Pros

• Restores multiple external displays on modern Mac systems that are otherwise limited to one, increasing productivity.
• Connects to both USB Type A and TypeC ports via the hybrid cable, adding flexibility for many host devices.
• Supports up to 2560x1440 at 60Hz for clear, usable desktop space on external monitors.

Cons

• Requires installation of the SMI driver and is not compatible with DisplayLink drivers, adding a setup step.
• Does not support HDCP playback, so it cannot be used for protected streaming content.

Our Verdict

For users who need to add one or more DisplayPort monitors without relying on USBC Alt Mode, this adapter delivers clear value: flexible connections, solid 1440p output at 60Hz, and compatibility across macOS, Windows, and ChromeOS when the SMI driver is installed. It is a practical, costeffective way to expand desktop space, though not suitable for HDCP streaming or those wanting a driverless plugandplay experience.
