PremiumCord MST DisplayPort 1.4 to 3x HDMI 2.0 Adapter for Monitors up to 8K @30Hz (3x 4K), Extended+Mirror+Duplicate Modes, Black

Adapter to connect a DisplayPort 1.4 output to three LCD monitors - Single DisplayPort for multiple monitors - You can use it for the extended desktop.

Supports MST (Multi Stream Transport), transmission of three images via a DP port - DisplayPort 1.2 and higher, which supports MST, is required for proper operation

DisplayPort input connector (male) - output connectors 3x HDMI 2.0 (female)

Supports standard DisplayPort 1.4 and below, requires no SW, plug and play installation, HDR10, 3D, DSC (display stream compress) and 7.1 sound channel

MICRO USB PORT FOR ADDITIONAL POWER SUPPLY - An external power supply must normally be connected to ensure proper functionality - Micro USB power cable is included

Support for Windows 7, Windows 8, Windows 10, Android - macOS does not support multi-stream transport (MST), so Extended mode is not available, only Mirror and Duplicate - Apple devices themselves activate the MST feature but must be run with an operating system other than macOS

Note Please add the additional power supply and make sure that the device supports MST. The product must be connected to devices whose specifications meet the requirements and must be supplied with an external power supply.

Note If the laptop does not have DP1.2 or higher, the adapter will not work. This is the most common cause
