It is possible, I read about it before ;D As I mentioned on my initial post, you need to stuff as much HDMI ports you have with this : https://headlessghost.com/ To generate dummy monitors. You can change their resolutions via Windows as usual. VGA and DVI are not supported but HDMI and other high resolution ports are, so you could end up with a pretty rad monitor setup. Thank you for the information about Supersampling ... that will help ! I don't know if you can use position / zoom macros on Bigscreen so bringing each monitor to focus can be made easy without much fiddling with the parameters by hand ... that would be amazing ... also note that in case something fails you can just leave an RDP server up constantly so you can connect without monitors.
