Does not work on second monitor

[jojonaloha]

I have a second monitor plugged in and the app does not appear to work on the second monitor. I'm using a Macbook Pro with a Thunderbolt display and the Thunderbolt does not get the same treatment when I switch between Normal Vision and the other options.

I was able to get it to work if I changed the Thunderbolt to my primary display or by Mirroring the display.

I believe this is a known limitation of the software, no plans to fix at this time (but Pull Requests are welcome).

This problem exists.

Yeah, it's a bit anoying if we work with multiple monitors, it repeat the main monitor on all screens.

Why not just aply it on the main monitor or better, the monitor we choose in parameters ?
