Black borders around Window

In Options --> Full Screen, I tried all the options available for Scale to fit screen. It didn't help.Have you tried either changing the aspect ratio that Win10 expects to see, or resizing the window so it fits?
Where can I change the aspect ratio?
Think you're confusing terms. There's Full Screen and there's windowed (You were showing a windowed display):
1. Full Screen fills the whole display with the VM, with no windows (small 'w') involved. That's what Parallels' Full Screen and Scale to fit screen menu items are supposed to do. If you're in Full Screen, Win10 should also detect the screen aspect ratio and attempt to fill it. If not, you have to set Windows' own display settings to something like 2880x1800 in Settings->Display->Display Resolution (that's actually from Win11, but there's something similar in Win10).
2. Windowed is what you were showing, not Full Screen. You could have always just resized the height or width of the VM window by dragging the top/bottom or left/right borders in/out (respectively) to make the black borders go away. Or, you can still go into Window's Display Resolution settings as with Full Screen to make it fit it with the correct resolution/aspect ratio.

Thank you for the details.
When I am in the full screen, Win10 is also stretching and filling the screen. So, it works.
It is when I am windowed, it is not working. I tried changing the resolution (I actually tried different resolutions) but it didn't work. Manually resizing the window is also not working.
I also observed that the "Enter Coherence" menu item is grayed out.
I want to uninstall and reinstall Parallels Desktop but I am not sure if my Windows 10 activation key works with the new installation.

Hello, I have the same problem. Could you tell me please where you find Options -> Full Screen and Scale to fit screen? Is it Parallels? Windows? ThanksIn Options --> Full Screen, I tried all the options available for Scale to fit screen. It didn't help.

Hello MarcelD, please refer to the knowledge base article https://kb.parallels.com/116141 to use the Parallels Desktop in full screen. ThanksHi,
I am using Parallels Desktop 17 and Windows 10.
I see black borders around the window. How can I get a full screen (don't want to waste space with black borders)?
Thank you.
