I ended up using this in a large teleprompter setup to correct for the monitor's reflection in the mirror. My client couldn't get used to Linux (which can flip the video output natively in the OS), so I switched the machine to Windows and used it to flip the video output horizontally on the monitor. An expensive solution, but it worked like a champ. The instructions that came with it were pretty sparse, but after a lot of fiddling I got them working for my use case. On the plus side, it retains all internal settings even when powered off, so it's a good "set and forget" tool for me.
