Is there a way to make it use only 1 monitor? I currently have two 1920×1080 and one 3440×1440. The biggest problem I am running into is artifacts on the screen when using NoMachine and I was thinking this would go away if I was using harware encoding and it crushing my CPU.
At the moment, the only way not to use all monitors is unplugging them physically from the server. Artifacts could be due to a bug in the H.264 software encoder with such a high horizontal resolution. Please try to use a different codec: open Server preferences -> Performance tab, check ‘Use a specific display encoding’ and make sure VP8 is selected, then restart the server and connect again.
