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.

It might not be possible. –  BenjiWiebe Feb 20 '13 at 3:40
    
What I can imagine is to use two monitors. Then you use a screen capture program to "film" the other. And then somehow you replay that video in real time on the other monitor, with a mirror "filter" enabled. OR you could just look into finding someone to design you a set of actual mirrors. Surely that's doable. –  Ariane Dec 1 '13 at 16:54
    
With old CRT monitors you'd get someone to swap the leads on the yoke. Dunno of a way to do that here. But it seems to me that the problem is with your simulator software -- it ought to be capable of flipping to the opposite orientation -- a very simple thing at that level. Have you contacted the outfit that created that software? –  Daniel R Hicks Jan 4 at 13:50

Try CONTROL+ALT then one of the arrow keys on the keyboard (up,down,left,right). Depends on your OS and keyboard but it usually does the trick. Hope this is what you're looking for.

http://www.minaware.com/ there you have Deskmirror inside that pack DeskMirror mirrors (reflects/reverses) half of your display onto the other half. You can play with its options to fit your needs (I didnt try 2 monitors enabled, just installed and it works) I hope it would be usefull for you
