Before opening the issue, have you...?

• Searched for existing issues
• Read through the Monitor-Troubleshooting Wiki
• Updated MonitorControl to the latest version (if applicable)

Describe the issue

In MonitorControl = 100% Brightness translates to "100" in the ProArt PA32UCDM Brightness OSD...while the OSD for Brightness can go to 400. Even if I quit MonitorControl, I need to physically bring up the monitor OSD and manually adjust the brightness setting to anything above 100.

I haven't done any other testing with different color gamuts thus far (only Rec.709 and Native).

Expected behavior

Control brightness through MonitorControl GUI where 100% = 400 on the monitor's brightness OSD, or control the exact brightness value from 1-400 in MonitorControl rather than a percentage.

Anything else?

In this image, you can see MonitorControl is set to 100. This set my monitor to Brightness:100. I then manually adjusted the monitor brightness OSD to 200.
