Its totally fine up to 40Hz, but blacks out at 33Hz.

How do I stop it going to 33Hz? I use the gsync demo by Nvidia, and it works great, but when i drop fps to 41, i expect the monitor to NOT go down to 41hz, because I limited the range. Instead, it carries on dropping to 33Hz, so instead of frame mismatches, I get black screens.

The monitor might not be able to handle the increased range correctly. FreeSync uses the max refresh rate as the base resolution, so that can affect the lower end as well. You might have to increase the lower end of the range. LFC is probably making it jump to 66 Hz when it's at 33 FPS.
