    Mac mini out of range signal

    Yesterday, I changed the resolution to x not a good idea and there was an "Input Signal Out of Range" error. So today I changed the resolution back, but the problem is still there. I've tried lowering the resolution all the way down to x but the problem still persists. I've noticed that under the "advanced display settings", the active signal resolution I guess the resolution that that the GPU is trying to send is still x , despite me setting the resolution back to its previous value, which is why the error is occurring, but I don't know why the GPU is doing this.

    However, this problem is only present with "extend these displays" with the dual monitors. If I select "duplicate these displays" so that the screen is identical on both monitors, the monitor works fine and the active signal resolution goes back to x so works perfectly. How can I fix this so that the monitor actually works again with "extend these displays"? View purplemackerel's answer. Hopefully this helps anyone with the same problem!
