Description

Is your feature request related to a problem? Please describe.
I have a very cheap, thin, portable monitor in a teleprompter with a beam splitter. Teleprompter software can flip its own content, but other software like PowerPoint presentations won't flip. I can only rotate the display in Windows 10, not flip it.

Describe the solution you'd like
I would like there to be an option in the new control panel to flip the virtual display. Then (hopefully) the flipped display could be cloned onto the teleprompter with other software.

Describe alternatives you've considered
The most popular alternative is to use OBS to capture a screen/window and flip it with the preview window on the teleprompter's display. This works, but I would prefer a more polished option that leaves OBS available for other things, like streaming different content to a virtual webcam or external server.

Another alternative is a hardware device that flips the image (they generally run around $400+) or a different monitor with built-in flip capability (also more expensive and thicker - so it won't fit in the tablet holder of the teleprompter as well).

There are limited commercial software options, but they seem to either flag for a trojan in virus total or haven't been updated in years, which are both cause for concern.
