Is there a program to visually work with 3 monitors from the main screen?

Question

Multimonitor

There is a system in which 4 monitors. 1 is on my pc and 3 are in another room. I need to put different pictures on these 3 and expand them to full screen. to do this is very inconvenient to have to ask a person to command where I should move the mouse. Is there a program that could be used to move windows that are already fully open to other monitors? Or a program in which, for example, all monitors will be displayed and I can place windows in them from the main one? or something like that.

Answer 1

Ibik aster, an application, allows you to make visually several independent windows from one computer with windows (not a server version!) and several monitors of mice and keyboards (each has its own windows user or even the same ones). Mice and keyboards are not required, each one can run its own instance of the vnc server and manage it remotely.
ps win32 api allows you to create a desktop (there was even a working example in the sdk) and bind each desktop to its own monitor, i.e. you can write a simple application that displays pictures, controlled remotely
pps linux has similar functionality out of the box
unfortunately it is convenient only if each workplace has its own video card, otherwise you can create a monster from Xephyr (this is a built-in xserver version that raises a full-fledged server inside any window in another instance of xserver)
pps you can deploy your own virtual machine on the monitors you need, controlling each one remotely using vnc /anydesk/teamviewer/... from the point of view of a person working at a computer, applications are running, if they are not touched, everything will work
