DP to DP adapter that supports dual display connection. - Type: DP to DP Adapter - Included Accessories: User Manual - Ports: 2 DisplayPort outputs - Compatibility: Supports DisplayPort connections only DisplayPort to Dual DisplayPort Splitter [Supports 4K@120Hz, 2 Display Ports + Power Port] DisplayPort Splitter 1 Input 2 Output Display Port 1.4 MST Hub Multi-Display Adapter 3 Screens Dual Monitor Duplicate/Extend Mode Compatible Connect 2 Monitors to a Computer Work From Home/Conference/Exhibition Lightweight Purchased for 3,390 yen on a certain online shopping site. My home PC has only one DP port, and I bought this to add a monitor and create a dual monitor setup. Indeed, two monitors displayed using one port. However, it seems that the resolution and refresh rate are sacrificed when using "two ports." Therefore, it doesn't suit my needs, so I am selling it. I only used it once to confirm its functionality.
