1.16K DP 1.4 Switch: Supports 16K@30Hz, 8K@30Hz, 4K@240Hz, 1080P@240Hz, offering transfer rates up to 48Gbps and is backward compatible with all previous DP standards. (A standard DP 2.1 cable is required to enjoy visual effects. If screen flickering occurs during use, try reconnecting or using a shorter cable.) 2.BiDirectional DP Switch: This DisplayPort switcher allows you to connect two DP sources to one DP display or switch one DP source between two displays. (Note: Two displays cannot be active simultaneously. Press the 'Select' button to toggle between them. When connecting to a source or display, use the included USB cable to power the splitter; otherwise, the display will not function. Avoid using excessively long cables—total length should not exceed 3 meters between the switch and connected devices.) 3.PlugandPlay (Not a USBC/HDMI Switcher/Splitter): Requires an external power supply. The DP switch box is easy to set up and operate. During use, press the 'Select' button to switch signals between two sources or displays—indicator lights will reflect the active status. Remember: Two displays cannot be active at the same time.
