I have an issue, where if I add/remove a monitor, my main monitor retains the splits I have set, but the other monitors "forget" that they had a split set up. This requires me to re-establish the splits every time I change monitor configurations. Is there a way to get the splits to save to the monitor? I'd imagine this is similar to docking/undocking a laptop, but in my case, I have a 4th monitor that I use for my work computer during the day, and I use a displayport switchbox to connect it back to my main PC during nights and weekends.

So I played around a bit, and found that if I manually select the profiles, the splits are there, but it doesn't automatically switch profiles. I also had this problem prior to 10.0, and after updating, my issue was unaffected.

so I have 4 monitors total, but have the 4th monitor connected to my work computer during the day, so when I'm off of work, I'm effectively connecting the 4th monitor. All the monitors have at least 1 split enabled. When I start work, I'm effectively disconnecting the 4th monitor, and going back to 3. I have a 3 monitor and a 4 monitor profile with the splits all set, and can manually select the profile and am off to the races. If I don't select the profile manually, only my primary monitor's splits are remembered.

Yes that sums it up. I am able to manually select the profile so I don't have to re-create the splits every time, but there's still a manual step involved.

Thanks for the reply. I did notice the monitor numbers were changing, and thought that might have something to do with it. I wonder if it has anything to do with the order of the ports the monitors are connected to, because this issue started when I moved some monitors around and likely plugged the monitors into different ports.
