Yeah but using HDMI as I also found for a wo´workaround , but not quite. Even hdmi is not working as expected and it is not the best option.
HDMI can only support 144Hz and the Display port to 165Hz for the Aorus F127Q .
And when using HDMI I also had to change Windows text appearance, It went horrible to read text from any website or PDF/ MS Word-documents etc:
Start > just type Clear > in the list run Adjust clear type
Strange it differ from hdmi to displayport, but I can live with that (one time setting) as long a new working driver that address this crazy thing about locked to 640x480 on the Aorus F127Q monitor.
solve the issue for my on FI27Q
downgrade frimware F03
then install new driver
can used DP 2k on 165Hz hope another can fix it to....
Thank you @naigaxeon for the workaround. I can confirm, that it works with 21.4.1. After all procedure I upgraded my monitor back to F05 and it still works fine. Please be careful with Monitor firmware operations and connect it to the UPS, because any power loss will brick your monitor.
Loose your hope, I have F05 since last year. Today amd realised new drivers 21.4.1 the same story no fixed displayport
