This article covers Plugable USBディスプレイアダプタ USB3.0 VGA.

Overview

The Plugable USB 3.0 Display Adapter is a compact external video adapter that adds an extra monitor via a USB 3.0 port. It supports resolutions up to 1920×1200 at 60 Hz and comes with interchangeable adapter heads for VGA, DVI, or HDMI outputs. Powered by the DisplayLink DL-3100 chipset, it draws power directly from the USB bus, eliminating the need for an external power brick. This makes it an excellent companion for travelers or anyone who needs a quick second-screen setup on a laptop with limited video ports.

Connectivity & Compatibility

Connectivity is straightforward: plug the adapter into a USB 3.0 Type-A port (USB 2.0 works but may degrade performance) and Windows will automatically install the DisplayLink driver. It is compatible only with Windows 11, 10, and 8.x — macOS, Linux, and ChromeOS are unsupported. If your PC only has USB-C ports, you will need a separate USB-A to C adapter or a USB hub. Note that each adapter drives only one additional display, so for multiple monitors you need multiple units. A separate video cable for the target monitor (VGA, DVI, or HDMI) is also required.

Product Info

Released by Plugable, this adapter sits at the entry-to-mid level in the USB graphics adapter market. It carries a 2-year warranty and email support. At around ¥13,174 (as of June 2026), it offers fair value compared to other DisplayLink-based competitors. The package includes the main adapter unit plus VGA, DVI, and HDMI converter heads, along with a quick-start guide.

Best Use Cases

First, business users who need a second monitor for presentations, spreadsheets, or research — it is much lighter than carrying a separate dock. Second, home office workers with older desktop PCs that lack extra video outputs can add a third or fourth display without upgrading the graphics card. However, this adapter is not designed for gaming, 4K video editing, or any GPU-intensive workload; for those tasks a dedicated graphics card remains the better choice.
