This article covers Plugable USB3.0 HDMI グラフィック変換アダプタ DisplayLinkチップ.

Overview

The Plugable USB 3.0 HDMI Graphics Adapter (DL-5500) is a compact external graphics adapter that lets you add an HDMI monitor to your computer via a USB 3.0 port. It supports resolutions up to 3840×2160 (4K) at 30Hz, and 2560×1600/1440 at 60Hz, making it a practical solution for expanding your desktop workspace. The adapter works on Windows, macOS, and ChromeOS, including Apple Silicon Macs (M1/M2/M3) after installing the DisplayLink driver. Because it relies on DisplayLink technology and USB bandwidth, it is not intended for gaming or video editing, but for productivity tasks like document editing, web browsing, and coding, it performs reliably. The device is bus-powered, weighs almost nothing, and is roughly the size of a credit card, ideal for travelers and remote workers.\n\n

Connectivity & Compatibility

\n\nThe adapter connects via a USB 3.0 Type-A port and provides a single HDMI output. It requires a separate HDMI cable to connect to your monitor. Maximum supported resolution is 3840×2160 at 30Hz, and lower resolutions (2560×1600, 2560×1440, 1920×1080) can achieve 60Hz. Compatible operating systems: Windows 11/10, macOS 10.15 or newer (with manual DisplayLink driver installation), and ChromeOS 100+. On macOS, some features such as screen rotation and clamshell mode have limitations. The adapter does not support HDCP, so it cannot play protected content. For systems with only USB-C ports, a USB-A to C adapter or hub (sold separately) is required. Multiple monitors can be added, each requiring its own adapter.\n\n

Product Info

\n\nThe Plugable USB 3.0 HDMI Graphics Adapter was released by Plugable and is widely available on Japan and other retailers. The typical retail price is around ¥13,154 (approx. $90 USD). The device measures just 25×25×25mm and weighs very little, making it one of the most portable monitor adapters on the market. It is fully bus-powered – no external power supply needed. Plugable offers a 2-year warranty and Japanese-language support. Internally, the adapter uses the DisplayLink DL-5500 chipset. In terms of market positioning, it is an entry-to-mid-range product aimed at business users and remote workers who need an affordable way to add extra monitors to laptops or PCs with limited video outputs.\n\n

Best Use Cases

\n\n- Remote workers or home office users who need extra screen real estate for productivity tasks like spreadsheet management, email, coding, or document editing. The adapter is perfect for turning a single-port laptop into a dual-monitor workstation without opening the chassis. Avoid for gaming or hardware-accelerated video editing.\n- Apple Silicon Mac owners who want to bypass the built-in external display limit (e.g., M1 MacBook Air supports only one external display). This adapter works with M1/M2/M3 Macs after installing the DisplayLink driver, though some features like screen rotation are limited. It is not a perfect solution but is the simplest way to add a second external screen.\n- Frequent travelers or on-site presenters who need a lightweight, no-power-brick solution to set up a second monitor quickly in hotel rooms or meeting rooms. The adapter fits easily in a laptop bag and can be deployed instantly. Note that if your laptop only has USB-C ports, you'll need a separate USB-A adapter.
