The UGREEN 55452 is a specialized display solution designed for users who juggle multiple devices but have limited monitor inputs. This 2-in-1 switcher allows you to connect two different video sources—one via USB-C and one via HDMI—to a single HDMI display, making it an ideal companion for professionals using a MacBook alongside a gaming console or a Windows laptop. Visual performance is a priority, with the switch supporting resolutions up to 4K@60Hz. It is backward compatible with 4K@30Hz, 1080P@60Hz, and lower resolutions. For a truly cinematic experience, the device supports 3D, HDR, HDCP 2.2, Dolby Vision, and Dolby Atmos for immersive audio, ensuring that high-quality content is delivered with minimal latency and stable signal transmission via an 18Gbps bandwidth. Designed for versatility, the switch is compatible with a wide array of hardware, including MacBook Air/Pro, iPad Pro, Steam Deck, ASUS ROG Ally, PS5, Xbox Series X/S, and Apple TV. To ensure functionality, the connected USB-C device must support DP Alt Mode. The device is strictly a 2-in-1-out switcher; it is not bi-directional and cannot be used in a 1-in-2-out configuration. Build quality combines a durable aluminum shell with ABS material, providing a scratch-resistant exterior and efficient heat dissipation. The compact, plug-and-play design requires no drivers, allowing you to toggle between your active inputs instantly using a manual selection button. To maintain peak performance, UGREEN recommends using a Thunderbolt 4 or fully functional USB-C cable (not exceeding 1 meter) for the USB-C input. While the device includes a USB-A to C cable for power supply, please note that a separate power adapter and HDMI cables are not included in the box.
