Displayport 1.4b to 2.1b? Firmware upgrade Hdmi 2.1a-2.1b?

Hi peoples,

Does anyone know if the hdmi port 2.1a to 2.1b on a rtx 4090 and dp 1.4a to 2.1b will be firmware upgradable?

Firmware 1.3 to 1.4a was available on my 3080 or 2080 ti a few years ago. I can't find any info about the new displayport and hdmi to be found on the 5000 series of graphic cards

Hi @soppingclam ,

thank you for the information you've provided. 
We've passed your details on to our relevant backend team for analysis. 
You mentioned that "previous RTX 3080 or 2080 Ti graphics cards can upgrade the HDMI and DisplayPort interface versions through a firmware update." Could you please provide more information on this? 

Have you previously upgraded the interface version of our graphics cards through a firmware update? If so, could you provide the full model number of your graphics card and specify which firmware version allowed the interface upgrade?

Your assistance in confirming this would be greatly appreciated.

Thank you.
