DisplayPort 1.2 to 1.2a / Adaptive Sync unlocking

post #1 of 3
Thread Starter 
Obligatory: I have UTFSE and didn't come up with much related to the DisplayPort versions. Hope this is in the correct forum section. I have to say that I really don't know what I'm talking about, so apologies for my lack of understanding/proper jargon.

Recently, AMD's FreeSync screen-tearing solution, a counter to NVIDIA's G-sync, was "spiritually" included in the DisplayPort 1.2a standard as Adaptive Sync. (Interestingly, Adaptive Sync Was NOT included in 1.3, but instead was included in 1.2a, which was released only a short time before 1.3.) AMD has said that the r9 290, for instance, will be able to utilize FreeSync, and possibly Adaptive Sync, despite being shipped with DisplayPort 1.2, not 1.2a.

NVIDIA, however, with its investment in G-Sync, will not allow its cards to use 1.2a - yet. Strikingly, the 900 series doesn't use the DisplayPort 1.2a standard. My question is this: can the features of 1.2a be unlocked with only driver or firmware changes? If so, even the 700 series might be able to take advantage of Adaptive Sync.

Edit: The r9 280x (which can't use FreeSync according to AMD, unless they're BSing for some profitable reason, aka r9 285) also shipped with DisplayPort 1.2. So it seems that there's more to this than I understand, to reference my intro.

Bump; anyone have insight?

DisplayPort 1.2a is an optional spec. Therefore unless it's advertised as 1.2a it won't have it.
