[BUG or My Computer] Monitors Don't show up in Nvidia Panel
Describe the bug I have been having an issue with games where I can't dictate what screen to use, I have to place steam on the screen I want the game to launch and I chacked Nvidia panel and my monitors don't show up. I also have been having and issue where the settings would revert back to default for one screen and they would change the order.
Expected behavior See my monitors in Nvidia panel and also be able to set what screen to use in game settings.
Screenshots
Desktop (please complete the following information):
- OS: Pop!_OS 24.04 (Upgrade from Pop!_OS 22.04)
Additional context I can add more information if needed, I am just not sure what is needed from me to help with this or this expected behaiver for now.

Does this work on Gnome Wayland, or other Wayland desktops?
It doesn't. The app is mostly informational on Wayland (with some OC options).
It should be the same on any other Wayland environment (e.g. Plasma Wayland).
Sorry, I am trying to understand what you mean, do I understand you correctly, right now this is a expected behavior because NVidia Panel is based on different Wayland and currently it won't really be useful. Sorry if I am asking this again I am just trying to understand this more and expand my understanding.
The NVIDIA Settings app was created at the time X11 was used, which is an decades-old (and insecure) protocol, which also can't properly support modern use cases (e.g. multiple monitors with different refresh rates or scaling, HDR, etc), since all displays are merged into one big display there in the background.
Wayland is the modern replacement for it, and almost everything is handled by the Wayland compositor (cosmic-comp in this case). That includes displays, and basically everything you see (the compositor interacts with the driver) or input.
The NVIDIA app could have display management options (similar to wdisplays), but there are already Settings apps that do that on each desktop environment (with potentially some unique features), and wdisplays as backup, so there isn't really a need.
There isn't a concept of a primary display on Wayland, but you can use a compatibility option in Settings > Applications > Legacy applications to choose a primary display to be advertised to legacy apps.
