The UGREEN CM620 is a practical HDMI splitter designed to distribute a single video source to four separate displays simultaneously, ensuring each screen shows the exact same content. It supports resolutions up to 4K Ultra HD at 30Hz using the HDMI 1.4 standard, while remaining backward compatible with lower resolutions for older monitors or projectors. To maintain high audio and video quality, the device handles a bandwidth of 340 MHz and transfer speeds up to 10.2 Gbps, supporting a wide range of formats including RGB, YCbCr, and advanced audio like Dolby TrueHD and LPCM 7.1. This black device features a robust housing and a simple interface with an on/off switch and LED indicators that let you know the power and signal status at a glance. Setting it up is straightforward since it works as plug-and-play without needing any drivers, powered by a DC 5V input. Depending on the cable gauge used, you can extend your signal up to 24 meters for 1080p content or 24 meters total for 4K signals, making it a reliable choice for those connecting a PC, gaming console, or Blu-ray player to multiple televisions in a commercial or home setting.
