S3220DGF, AMD FreeSync on, brightness changes/flickering, #3

Hi.

I have just finished a triple monitor setup with S3220DGF but the things backlight/gamma something, flicker when AMD FreeSync is in use! Why? And unfortunately, searching for solutions I see I am not alone. C'mon how did this pass QC? Please, is there any firmware update that fixes this?

Thank you

Intel 9900k

Amd 5700XT latest drivers

Also tested with Nvidia 2080ti using latest drivers

Windows 10 1909..

Drivers are not responsible for this brightness/gamma flickering. I tested a few driver versions with both GPU with same results. Freesync enabled from GPU side and darn things flicker. Around 90Hz / 90 Fps it is so bad is makes me nauseous.

All Monitors are connected via display port, tested a few cables, same results.

I have tried multiple custom frequency 90 100 120 144 all of them flicker. I even tried changing freesync range with CRU, same results. They flicker when freesync is working, like all people are reporting all over the internet.

I am most definitely returning them because no manufacturer is going to solve this quickly and return window is getting short. I don't see dell having a user way to update monitor firmware so I am out of options. It is sad because monitors are very nice otherwise.
