How to reset monoitor vsync under Windows 10

I need to support a multichannel visual system based on several PCs with the same HW and the same type of monitors attached.

One of the synchronization problems is a different phase of monitors vsync. I’m using 60Hz monitors and sometimes the resulting difference between not corresponding frames on neighbors monitors is noticeable.

Unfortunately, the monitors do not support G or Free sync.

The idea is to use network broadcasts and somehow to reset monitors vsync to the same definite phase.

So does anybody know a proper method for doing that under Win10?

I know that in some rather short time the monitors would be desynchronized so it would be nice if the method would be possible to call periodically.

Thanks for reading.
