Your welcome, sorry it took longer to identify the fix. 
I could be wrong. But I think @john2910 might have the 5kXR. If so he or @SweViver should be able to help identify model.
There is I believe is headset settings that only pertain to the oled model. And If has changed refresh is 85hz?. See refresh options.
It should also say “Pimax 5K XR” (I think) on the status page when headset is connected.
At least the other models are identified there when connected (Pimax 5K Plus, Pimax 8K)…

Your very welcome! The community here is very good with helping one another. With 85hz that should be the Oled 5kXR.
Congrats & enjoy! To help Support if everything is Resolved. Send them a message letting them know your headset issue has been fixed.
