DisplayLink Brightness/Contrast Sliders Unmovable at 0

Hello,

I've been using a Plugable DisplayLink product for a very long time, and I know it works well with the two projectors I am using (that do not have support for brightness/contrast adjustment). However, the DisplayLink manager auto-updated to version 1.12.1 (it was previously on 1.12), which I believe introduced the brightness and contrast sliders. They are unmovable (since the projectors don't work with DDC tech) and stuck at zero.

This is why I think that I can no longer see anything outputting from both projectors. Is there any way to downgrade the software version?
