Hey, yes, I am still working on this but I should be able to provide you with an update shortly.I contacted Dell very shortly after I got my monitor and realized the issue and they were actually fairly prompt in agreeing to do an exchange, but I think they misunderstood because they exchanged it for the exact same model (as I think I mentioned above).  So after that things got a bit muddy and I really had to press them.  I think posting here may have helped my case, and I was able to contact someone on the forum who gave me explicit instructions around describing my issue.  I should make it very clear that NOT ALL A03's are capable of 120hz 1440p.  It has to be an A03 Manufactured after June 2nd 2020 (mine was an A03 From May 2020). So when you contact dell support:"Tell Technical Support or Customer Care to open the Dell internal OKB (Oracle Knowledgebase). Tell them to search for SLN322482 = Dell S3220DGF Has a New 120Hz Refresh Mode with Firmware Revision A03 "Because I went back and forth with support for a while who assured me that my model was capable of 120hz 1440p.I have been shipped yet another monitor and I should be able to get it this evening... If I don't message on here again, it's because I'm blissfully gaming at 1440p and 120hz... if that's not the case you will hear back as I will be back on here talking about it.  
I live in Canada, which has caused issues in talking with support.  I recently purchased an S3220DGF for use with my Xbox Series X, however upon receiving the monitor I realized that it was unable to do 120hz at 1440p via HDMI.  I encountered many other posts online of this issue, wherein I discovered that a refurbished monitor exchange manufactured after June 2, 2020 was required to fix the issue with an updated monitor EDID.  I did the exchange and found that the monitor I received was the EXACT SAME with the same outdated EDID, manufactured May 2020 A03.I have tried to express this to Dell to no avail.  They have attempted to connect me to Customer Care multiple times and each time I get disconnected.  When I try and call the number they gave me I get general technical support.Please help me.  I just want to exchange this for a new monitor with the proper firmware and HDMI 2.1 port so I can play at 1440p and 120hz, which is why I bought the monitor in the first place!
S3220DGF, need exchange to revision A03 or later
