If you want to display the images of multiple remote desktops on a single display at the same time, there is still no other. The technology or method provides centralized monitoring of multiple remote desktop images simultaneously.

In the technology of remote desktop applications, the Remote Desktop Protocol (RDP) technology developed by Microsoft has been widely used. When using RDP, the computer's central processing unit will have a lower burden. This is because the computer's operating system itself does not need to actually perform the drawing action, but instead sends a drawing instruction to the client via Ethernet. That is, the end of the user's operation makes it draw. Therefore, the RDP has the advantages of small transmission packet, no bandwidth, low computer operation consumption, and high frame rate of the client. However, the transmission protocol of RDP is only a one-to-one remote operation technology. Even if multiple users are connected to the server at the same time, each user is independent, and it cannot provide any user to display other uses at the same time. The picture of the person.

Therefore, there is still no way to achieve centralized monitoring of multiple remote desktop images on a single display while taking advantage of RDP.
