Yeah, the free version and even the cheaper paid version is no use if you have multiple monitors. You need the expensive 'Pro' version for that. I prefer Mouse Without Borders from Microsoft Garage anyway. I've been using it for years to control several PCs. It's not perfect (a simple script or two automatically deal with the occasional glitch) but I couldn't live without it. Well, I could, but it would be a pain.
I use RAdmin for years already with great success! Just recently got a problem that one friends computer couldn't be accessed using RAdmin. Digged and found that the problem is TCP IP v6 isn't supported by RAdmin yet, just TCP IP v4!
RAdmin just gives you up to 100% Remote Control over the other computer, not only on local LAN, over the Internet as well, without the need of any other 3.party service than a internet connection! If looking at the System Requirements of ShareMouse, that's just terrible! And I would never pay any single cent for such apps! With those limits, it wouldn't suit's my requirements of such software!
ShareMouse does not bring the monitor of the remote computer to the local computer. I think it is different from Radmin. Ramin is similar to TeamView, RealVNC, or Remote Desktop. ShareMouse is similar to Synergy, Mouse without Borders, or Multiplicity.
For that, I could just use a simple KVM Switch. without to use the Video function, would be exactly the same, or maybe even better! I use RAdmin for Remote Control in my work because it's secure and fast, even over the Internet! TeamViewer, as example, would run over an 3.party System/Server, while RAdmin is directly connected to the Target.
I know that. I just want to discover a software program that is similar to KVM Swich. I don't need it for my work
