A new wireless device from UGreen, featuring a USB-C transmitter and a magnetic wireless HDMI receiver, has been evaluated by Ph. Adrian Kingsley-Hughes from ZDNET. The device aims to replace traditional HDMI cables by allowing users to transmit video signals wirelessly. The transmitter side connects to a device with a USB-C port, while the receiver side connects to a display such as a television or monitor. The system works with a wide range of devices, including Windows, macOS, and Linux computers, as well as iOS and Android smartphones and tablets, and devices with DisplayPort ports in alternate mode. The receiver needs to be powered using a 5 V/1 A power supply, which can be drawn from a USB port on the television or screen. The device operates on a 5.8 GHz wireless frequency, which is different from standard Wi-Fi networks, reducing the chance of interference. In optimal conditions, it can transmit 1080p resolution at 60 frames per second over distances of up to 50 meters. However, this range can be affected by obstacles like walls or furniture. The transmitter and receiver are connected using a magnetic clip, making it easy to attach them to each other or to a smartphone. Both components are equipped with a cooling system to manage heat during extended use, though they may warm up slightly. It is important to note that the device is limited to 1080p/60 Hz resolution and cannot send signals to multiple receivers at the same time. Priced at 83 euros, the device is marketed as a versatile solution for individuals, schools, businesses, and professionals who frequently work in different locations. It offers a convenient alternative to wired connections, though users should be aware of its limitations in terms of resolution and multi-receiver support.
