Install the appropriate version of the update package by running the Windows6.1-KB2592687 update file. 2. Restart the computer. 3. Open the Local Group Policy Editor. 4. Enable the Remote Desktop Protocol policy. The setting for this policy is under the following node: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment 5. If the UDP functionality is required, enable the RDP Transport policy, and then set the value to *Use both TCP and UDP*. The setting for the RDP Transport policy is under the following node: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections Note Configuring the RDP Transport policy also lets the firewall allow UDP port 3389. 6. Restart the computer. Very easy to do and now multimon works fully with 4K displays, or at least a 4K and FHD display.
