I have searched dozens of forums for this solution on multiple occasions, and the answers are always instructions on monitor rotation or simply, Why do you need to do that anyway?
Yes, I can rotate my monitor, but that doesn't address my need. I work with amputees and have a virtual model of a right arm that they control in real time using advanced surface electrode control strategies. I've been stuck using this right hand virtual arm with individuals who lost their left arms, and that can be distracting. Until an identical model exists for both arms, I'd like to simply flip or invert the screen horizontally to produce a mirror image. This would give me a left arm model that would function just like the right. I make the arm a full screen image, so there is no concern about backwards text, etc. It would be nice to toggle back and forth with this monitor flipping, but that's not critical.
I run the signal processing, decoding, and visualization on an ASUS G75 with the NVidia GeForce GTX 660M. The computer can handle quite a bit, so even if the proposed solution was CPU intensive, I don't think that would keep me from running the real-time simulations I use.
There are no built-in inverting features in the NVidia control panel that I can find. There are plenty of flipping options, but there are no mirroring or inverting options. Any suggestions are much appreciated.
Updates: I am using Windows 7. The Ctrl+Alt+Arrows are shortcut keys to rotate the display. Suggested answers to the identical question from a couple years ago are all either 1) rotation tips, 2) Why do this anyway? or 3) use your video card's built-in features. I addressed all of these in previous paragraphs. Perhaps it is not possible with my NVidia GeForce GTX 660M and Windows 7.

Try UltraMon. It lets you flip both vertically and horizantally (independently). It also provides a number of other useful features for using multiple monitors.
