I am looking for a remote desktop viewing software we can install on a few dozen machines. UltraVNC works but some people have suggested a tool called Radmin which actually performs better (better screen resolution and faster refresh rates). Ideally I would like something that has a portable install because it will make automated deployment easier.
Windows Remote Desktop won't work because it actually takes over the session. We need a real viewing software that doesn't change anything on its target machine.
Any suggestions? Are there better VNC versions than UltraVNC?
For performance, NoMachine[0] offers a near native experience on most connections, especially locally or in situations with sub-50ms latency.
For a portable client, AnyDesk[1] is created by an ex-TeamViewer developer and is very straightforward, while still maintaining better performance than VNC.
For general use, TeamViewer[2] is still a good choice.
Radmin still outperforms VNC in most cases, however it's competitors seem to currently outpace it, and many things about the company and software feel like a legacy environment.
