Command line support for CONTRAST?

[DRSAgile]

Hi,

My monitors' overall brightness is so high for my overly sensitive eyes, so it is always set to zero, and the only parameter I control is contrast. (And if I were to set contrast to a low value and would use brightness instead, then I get a washed out, low contrast picture, so it is not a variant.)

Thus, if possible, I would ask to add command line support for adjusting contrast. I would need it in my attempt to build a script that automatically updates monitors' settings depending on data from a light sensor.

Thanks in advance.

This is already supported via the --VCP flag, using the VCP code 0x12. For example:

"%LocalAppData%\Programs\twinkle-tray\Twinkle Tray.exe" --MonitorNum=1 --VCP="0x12:50" ... will set monitor 1's contrast to 50 and ...

"%LocalAppData%\Programs\twinkle-tray\Twinkle Tray.exe" --MonitorNum=1 --VCP="0x12:75" ... will set it to 75.

Thanks. Could you please add this example to the documentation?

It would be nice the app to have user friendly name for changing contrast and RGB via command line instead of using VCP flag. Like ClickMonitorDDC.
