Hi,

I just upgraded to "AMD all in 1 with VGA driver ver:19.10.16_19H1_WHQL", however I noticed I'm no longer able to control the monitor's brightness settings trough the DDC-protocol when using that version.
Programs's such as the one provided by LG and ClickMonitorDDC no longer detect my monitor.
Downgrading to "AMD all in 1 with VGA driver ver:18.50.16.01_WHQL" solves the problem.
Monitor is a LG 27UK650 connected via displayport.
Is there anything else I can try? I would like the use the most recent driver..

Thanks!
