Expand Your Desktop: Plugable USB 3.0 to HDMI 4K Adapter

Need an extra screen without cracking open your laptop or PC? The Plugable USB 3.0 to HDMI 4K DisplayLink Adapter is a simple, powerful solution for adding another monitor—even if your computer doesn’t have a built-in HDMI output.

What It Does

This adapter converts a USB 3.0 port into a full 4K HDMI display output. That means you can plug it into just about any modern Windows, macOS, or ChromeOS machine and instantly run an additional monitor up to 3840x2160 resolution at 30Hz.

Perfect for work-from-home setups, dual monitor workflows, or just giving yourself more breathing room on the desktop.

Key Features

  • Supports resolutions up to 3840x2160 @ 30Hz

  • Fully compatible with Windows, macOS, and ChromeOS

  • Powered by DisplayLink technology

  • Works over standard USB 3.0 Type-A ports

  • Adds a second (or third, fourth, etc.) monitor without opening your system

  • Multiple adapters can be used to drive up to six displays on Windows

  • Ideal for office use, light video playback, and extended workspaces

Who It’s For

  • Professionals running multi-monitor setups on laptops or small form factor desktops

  • Remote workers with limited video outputs on their computer

  • Mac users wanting to bypass the single-display limitation on base M1/M2 systems

  • Anyone who wants a quick, plug-and-play way to add an external display without upgrading their entire machine As an Amazon Associate, we may earn from qualifying purchases. This helps support the work we do, at no additional cost to you.

Thank you so much for this post! I have an older HP Notebook, and have spent way too much time and money trying to find a solution to a multi-monitor set-up. 👍
