A month ago or so I went through Adored TV's list of panels and a clear trend emerged that aligned with GPP: Taiwanese companies + LG (South Korean) took the same monitors that were exclusively FreeSync and rebranded them to G-Sync Compatible + Vesa Adaptive Sync removing all AMD FreeSync branding. American + Samsung (also South Korean) companies didn't do that: HP and Razer in particular didn't change their website at all to reflect G-Sync Compatible support while Samsung debuted a completely separate model number for their G-Sync Compatible monitor.
The question is whether or not NVIDIA is putting the requirement of removing AMD FreeSync branded or are they doing it of their own volition. Two theories why they're doing it on their own volition:
1) Performance: FreeSync (basic adaptive sync support) -> G-Sync Compatible (panel has to pass more tests to get certified) -> FreeSync 2 (even more stringent tests required than G-Sync Compatible)
They may be branding based on which threshold it supports because all the panels that are adaptive sync compatible will work with G-Sync Compatible and FreeSync (and Intel when they debut next year presumably)...they just might not perform as well.
2) Marketing: These monitors (that I checked anyway) were released before G-Sync Compatible debut. They may have felt that everyone that was going to buy their panels for FreeSync support already did so they're trying to maximize their marketing for the G-Sync crowd that is less saturated. Of course this point can't really explain why they stripped FreeSync branding entirely because it shouldn't hurt to mention both (think Crossfire+SLI support years ago).
I think #1 is most probable. We'll have to see if a G-Sync Compatible monitor debuts that also supports FreeSync 2: does it say "FreeSync 2 + Vesa Adaptive Sync?" If so, then they're trying to disambiguate actual monitor performance from basic feature support which does make some sense.
As always the first question here SHOULD be: 'what is the official AMD response'?
AMD's response to GPP was "hey, look at this," to Kyle Bennett. AMD prefers the press to make an example of NVIDIA than resorting to litigation. Perhaps because AMD can't litigate it without regulators making a move first (which requires press coverage). Perhaps because if AMD goes directly after NVIDIA, it could result in a tit-for-tat that will ultimately result in patent cross-licensing disputes that AMD doesn't want either.
Bottom line is this: don't trust marketing on monitors. Use the AMD/NVIDIA lists:
