S3220DGF, AMD FreeSync on, brightness changes/flickering
Hi,
I have a problem with Dell S3220DGF. When AMD FreeSync is turned on. It is fine when it is off. When it is turned on, the screen is visibly flickering in games while in desktop mode it is fine. I have tried many things and I am starting to think that it is a panel problem. I have tried different driver versions from branches 18.x.x, 19.x.x, 20.x.x (used DDU every time). I have tried changing refresh rates and FreeSync FPS range. I mainly use MSI R9 290 but I checked also on RX580 and it is the same (full spec below). Monitor is connected directly to GPU via DP. The flickering looks like the one presented in this video (not mine):

Spec:
Monitor firmware: M3C101
Windows 10 (10.0.18363)
GIGABYTE GA-990FX-GAMING
AMD FX-8320
MSI R9 290 / Sapphire RX580
Hi,
I just got my new S3220DGF. Flickering is happening usually on some game loading screens.
Where the frame rate is rapidly changing and freesync is on.
I would like to submit this problem to dell for a firmware fix but no support is available.
Its a small issue for me. It would be nice if they fixed it.
Same issue in any full screen app, like youtube or twitch, also in games. Without FreeSync everything is ok. I noticed activating freesync in the monitor menu lowers to 164 hz the max frequency at system settings, may be bad sync because no integer fps scaling possible?
Is there any posibility of fixing frame rate to something more standard like 144 or 120 hz despite freesync is active or not? Just to check out.

I have tried several monitors and practically everyone has this problem in certain frequency ranges. I don't understand how they never talk about it in the reviews.
