I have the same monitor and use it with Freesync Premium Pro. No flickering for me.

What is the resolution and refresh rate you are running at?

@Vanadiel​ 
3440x1440 165Hz

Link added to original post. Was also very noticeable during display calibration with an X-Rite i1DP.

Interesting. I talked to my contact group, see what they come up with.

How are your frame times with and without Freesync Premium Pro?

@Vanadiel​ 

Was using Rivatuner with text+graph. Frametimes looked normal. I tried VRR off, Freesync Premium Pro, and basic Adaptive Sync (OSD HDR set to Off while in SDR mode).

The only recourse I could find was on pg.89 of the user manual which explicitly says to disable G-sync/Free-sync if Screen flickering occurs.

I've tried different cables, including cables with ferrite cores.

Maybe it's LFC (Low Framerate Compensation) triggering when it shouldn't? Theres other repeat examples like my video on YT.

AW3423DWF firmware M3B106 was released today February 6, 2024. It doesn't mention flicker but consider installing and testing it.

Fix to intermittent screen corruption and image degradation during heavy graphical load

@DELL-Chris M​ I am going to try that when I get home tonight. I will let you know how it worked out,

@Monitormans​ I had some higher than average frame times when using Freesync on this monitor on Diablo IV. I have now a more consistent frame time of around 6 msec at 165Hz using maxed out graphic settings. Before it was around 8-9 msec. the frame time graph is flatter without freesync.

I measure it both using rivatuner and Adrenalin software. I actually put the rivatuner graphics up on a second monitor so I can visually monitor whatever I want to monitor during actual game play.

@DELL-Chris M​ Success, fixes the flickering with Freesync Premium Pro in darker scenes. Will see if the frame time is more consistent also, but so far so good.

@DELL-Chris M​ Did not fix my issue. p89 manual flicker solution only recourse.

I have the same problem, the flickering with G-Sync compatible enabled is very annoying.

It seems its because of unstable frame times in games and LFC (low framerate compensation) and it darker areas its a way more noticeable. unfortunately there is no real fix, rather than turning VRR / GSync off completely.

@ch.sel​  yeah it occurs in quite a few games. unfortunate.

It's particularly bad in Alan Wake 2 as it's dark and its really really distracting.

I don't understand ... I bought an alienware desktop with an alienware QD OLED VRR monitor touted to be the best gaming monitor, and I find that it flickers when using VRR ... and it's mentioned in the official troubleshooting where the accepted soution is to disable VRR, one of the main features of the monitor?

I updated it to the latest firmware and it didnt fix it.

Another workaround found online is to switch to nvidia color settings in the Nvidia Control Panel / Change Resolution page, decrease the refresh rate from 156hz to 100hz (apply) then increase the output color depth from 8bpc to 10bpc.

But then why did I buy a 156 hz monitor worth £900+?

Surely Dell is doing something about this, where are the official updates on addressing this ? 

Yeah it's still present with firmware M3B107. I run VRR disabled to get rid of it per the user manual and do my best to smooth framerates with limiters most the time. bummer.
