UGREEN CM617 Wireless Smartphone Display Adapter
The UGREEN CM617 Wireless Smartphone Display Adapter is a versatile wireless HDMI screen casting solution that lets you mirror or extend your smartphone, tablet, or laptop display to a larger screen — such as a TV, monitor, or projector — without cables. Designed for seamless screen sharing, this adapter supports high-definition resolution up to 4K (3840×2160) and uses dual-band Wi-Fi (2.4 GHz & 5 GHz) for smoother, more stable wireless transmission with reduced interference. With easy plug-and-play setup, simply connect the adapter to the HDMI port on your display and cast from your device using built-in screen mirroring features (e.g., AirPlay for iOS/macOS, Miracast for Android/Windows). This makes it ideal for watching movies, sharing photos, gaming, delivering presentations or browsing content on a large screen with minimal lag. The CM617 supports both horizontal and vertical screen orientation with one-click switching, so you can effortlessly adapt between widescreen viewing and portrait content — perfect for social media feeds or short videos. It works with a wide range of devices including Android phones/tablets, iPhones, Windows laptops, and macOS computers, offering flexible compatibility for home, office and classroom environments.
