Incredible Picture Quality
Supporting four times the resolution of 4K, this DP 1.4 MST hub delivers the stunning quality of UHD at resolutions up to 7680×4320 at 30Hz on a single monitor and supports multi-monitor applications at lower resolutions and refresh rates, enabling a dynamic work environment whether you're in the office, at home or traveling. Both your source and destination must support DisplayPort 1.4 in order to achieve maximum resolution (8K 30Hz). Lower resolutions and refresh rates may also be supported.Multi-Tasking Made Easy

Using this multi-monitor video splitter, you can mirror your display onto multiple monitors, stream independent content to each display or extend your screen to create a video wall effect.Hassle-Free Setup
