Hi, I have a program that is giving me headaches when I want it to run on my primary display, even if I want the program to run on the second display, it continues to give me problems. I was informed I need to tell Windows that the primary display is really the second display, as if the primary display didn't exist and there is only one display. I know that may sound confusing, hopefully someone can expand on this ?

There can only be ~one~ primary display.

Fullscreen applications can ~only~ open on the primary display.

Ways to get around this:
-Temporarily change which display is primary.

For example, Steam Big Picture allows you to set up which display you want acting as the main display. Then, it will switch to those settings when you open it and it will switch them back when you close it.

With DisplayFusion, you could set up display profiles and have rules for each of them. That way, with a simple hotkey, you can make your second monitor your primary display and switch it back when you're done.
If need be, you can play around with Window Location rules for this profile so as to keep new windows in your (now) secondary display.

I'm sure the devs will be able to expand on this better than me.

What are the command lines I can use in Display Fusion, the manual doesn't have a list ?

Is there a keyboard short-cut in Display fusion CTRL+SHIFT+A that could cause a browser, in my case, chrome to minimize and maximize, it's interfering with another program I use. I'd like if the Dev Team could reply

This question is probably going to appear vague, I'm hoping you can help to figure this out. As you probably are aware there is another program called UltraMon, the issue I'm having with a program is that each time I want to load it up, it crashes.

This is what I was informed that needed to be done, using the program UltraMon, I know it's possible with Display Fusion. You can supposedly apply any COM window object in Windows itself. If I want a program to load up in the monitor on the right, with UltraMon you have to place the window 1280 pixels from the left-top origin to get it to appear on the secondary monitor.

I hope that makes sense, that is the absolute best way I can describe what I want told, as that was exactly how I was told.

Here is another representation of the above; the second monitor as to behave as though it's the first monitor, sounds confusing I know. I really hope you can help me figure out what is exactly the problem, that is the best I can describe. The problem is related to only one program, everything else at the time is fine.
