Fullscreen apps to specified monitor?

Hi,

My setup has one monitor that is always on, and one LG OLED TV that only gets turned on for fullscreen games.

I'd like to have things set up so that any windowed program defaults to the monitor, and anything that maximizes or goes into exclusive fullscreen mode goes to the TV. Is there any way to do this without setting up triggers for each individual game?

Failing this, I'd want to set the monitor as primary, so the miscellaneous small windows would just stay in place no matter whether the TV was on or off. But with the monitor as primary, games would always open on the monitor. Some games were fine being moved to the TV, either manually, with hotkeys, or with the setting to move new windows to the location of the parent window, but others would crash, lose their HDR support, or have other issues. So to avoid that, I had to set the TV as primary.

But this means that when the computer goes between monitor-only and monitor+TV profiles, all the windows get moved around, and the taskbar goes to the TV. I was able to set up a window position profile and set it to automatically restore when the monitor+TV profile is loaded, but this isn't ideal, as it only saves the specific programs I had open when I saved it. What would be preferable would be a setting that says that any windows and taskbars on the monitor should stay exactly where they are, regardless of a new primary display being set or unset.

Is there anything that would solve these issues? Sorry if this is kind of scattershot -- I've looked through everything I can find, and it's annoying because I can see a number of different ways that this all could work correctly, but none of them seem to actually exist.

Thanks!

There isn't a way to prevent the Windows taskbar from being moved, unfortunately.

As for the window positions though, you can set key combinations on the "Save Window Positions" and "Restore Window Positions From Last Save" functions on the DisplayFusion Settings > Functions tab.

If you run the "Save" hotkey before loading the profile, then run the "Restore" hotkey after, it should put all the windows back where they were.

Unfortunately for the most part, DisplayFusion can't force native full screen games to a non-primary monitor.

Please let us know if you have any further questions at all.

Thanks!

Thanks for confirming. Is there any way to force the system not to change display profiles, and lock it to the current profile? Just have it pretend that the TV is always connected so it doesn't try to reconfigure things whenever it turns off and on? I know some things might get lost on the missing screen, but gathering them with the hotkey would be easy enough compared to having to move them back.

There isn't a way to do that in software no. If the TV is connected via HDMI, some customers have reported success with a device like this, which basically just blocks the HDMI pin that tells Windows that the TV is off: http://monitordetectkiller.com/
