Screen tearing on cloned display that is not preferred

I recently replaced my GTX 670 with a R9 290X.

I have 2 monitors connected via HDMI (1080 and 1050) and a 1080p TV via HDMI that duplicates the primary screen.


With the new AMD card I experience screen tearing in the bottom quarter (like vsync off but always the same spot) of the 1080p display that is currently not set as preferred.

Setting the color format to 4:2:2 on the TV output doesn't seem to fix this issue regardless of which screen is preferred.

Is there any way to operate these mirrored screens without having to tediously switch preferred displays?


Alternatively, is there a way to make a shortcut to switch preferred screens, perhaps by some registry edit?
