G-sync firmware update to work with AMD cards

Does anyone know if it is possible to get firmware yourself to upgrade g-sync monitors to work with AMD cards?

I just researched this. The TLDR is there are 3 versions of Gsync;

1) Gsync supported (Software V-Sync)
2) Gsync v1.0 (Hardware Vsync, AKA original G-Sync)
3) Gsync v2.0 (newer hardware vsync)

1 and 3 are AMD supported. If your monitor is Gsync 1.0, there wont be a firmware update for AMD freesync support.

There are articles out saying that the 'old' Gsync cards would get updated. To date that has not happened. Adaptive sync requires compliance with a DP implementation, which Gen 1 Gsync doesnt have apparently.

I've heard reports of a couple monitors running the gsync v1 working with AMD cards, such as the AW3420DW that rtings.com tested. But dell is clear that this isn't officially supported and they only support gsync with nvidia cards if you need technical support. So the original gsync are capable with a firmware update from what I've researched. Are you saying that it would be limited to HDMI on the v1 monitors?

A monitor will 'work with' anything. Adding in sync is different; Adaptive sync is DP 1.2a only, it has nothing to do with HDMI.

Gsync is hardware pushing to other outputs. This is one of the reasons that v1 wont work with adaptive sync without a firmware update.

(Also, the 20dw has 2.0 gsync in it.)

By work I meant the adaptive sync (i.e. freesync). Hmmm, I thought the AW3420DW was the passive not active cooled gsync modle, which I think of as v1.
