ArbaroClara Displayport to Dual HDMI Splitter 1 in 2 Out, 4K 60Hz DP 1.4 to Dual HDMI 2.0 Adapter Port, for Laptop Computer Monitor MST/SST/Extend/Copy Display(Mac OS Mirror Only)

Extended and Mirror ModeThis DisplayPort to HDMI splitter supports Extended and Mirror Mode.
Extended Mode: The computer and two monitors can display three different images respectively (ABC).
Mirror Mode: The two monitors display the same image (AAA/ABB). ^^ Please check the device ports (input: DP port;
Output: HDMI) before purchasing. Most integrated graphics cards can only operate in mirror mode. If you are unable to obtain the extended mode, please update your graphics card driver to the latest version ^^ MacOS
Display Limitation: macOS does not support MST (Multi-Stream Transport), allowing only screen mirroring without extended display mode. This means Mac systems cannot drive two separate displays as extended desktops.
^^ Ultra HD Resolution: Supports 4K@60Hz resolution on a single display with backward compatibility; simultaneous dual-display output supports 4K@30Hz, delivering an Ultra HD visual experience. ^^ Before purchasing, ensure your computer is equipped with a DP (DisplayPort) interface. This product is incompatible with docks, hubs, or adapters.
(Note: HDMI cable not included) ^^ Before use, ensure display settings are in extend mode with external monitor connected and powered on. If extended display fails, adjust settings to extend mode and confirm monitor is on. ^^ If the graphics card does not support MST technology, cannot achieve an extended display across two monitors, and cannot use a DP-to-HDMI adapter to connect to the HDMI port of this product. ^^ This splitter adapter requires your computer's graphics card output interface to support DP 1.4 /DisplayPort++ or higher specifications. Use HDMI 2.0 or above certified HDMI cables, ensuring the cable length does not exceed 1.8 meters.
(Note: USB power supply is mandatory for stable adapter operation. ) ^^ Plug and play, no driver required. Connect the USB power cable first, then interface devices. (Power cable must be connected first to prevent display issues).
