Hi there, new user after using the trial for a couple of days, very impressed! One issue I do have is that the auto split function for Nvidia surround doesn't appear to be working. I've selected the auto 3 horizontal mode instead and adjusted the monitors slightly (3 x horizontal) and so I can't use the snap feature on the edge of each monitor bordering the next monitor if you get my drift.
I see another post just below with someone also having the same problem, just letting you know that it's not just him! Problem hasn't stopped me buying DF, couldn't imagine going back to not using it now after only a week.
Thanks for trying out DisplayFusion, glad to hear you like it! When using Surround, Windows sees the 3 monitors as one large display, so it doesn't actually know about the borders between the monitors. We haven't replicated the Aero Snap functionality in DF yet, so we can't tell the windows to snap at the monitor edges either. So, it's not really a bug, but more of a feature request/unimplemented feature.
We'll be sure to post an update if/when we're able to implement a clone of the Aero Snap functionality in DF
