As far as I know, it should be in all 144Hz+ TN
G-SYNC monitors, yes.
I believe, and from all anecdotes I've read 3D Vision had always worked on the TN ones. Generally, it has been package deal for 144Hz+ TN panels, G-SYNC + ULMB + 3DVision is part of NVIDIA programming in TN G-SYNC firmwares. But not on all G-SYNC monitors in general.
There are 100Hz and 120Hz G-SYNC monitors that does not even manage to have strobing, due to panel limitations (e.g. VA, IPS).
See List of G-SYNC Monitors
for G-SYNC monitors with ULMB, versus without ULMB. Generally, if it's TN and if it has ULMB, then it also has hidden 3D Vision support too.
There are 3D Vision compatible displays not even listed on NVIDIA's official list of 3D Vision Ready displays
. This may be because that particular display may not have the LightBoost backlight overvoltage technique
of brighter strobe flashes. If it doesn't have that, it's not allowed to be officially advertised as LightBoost
or 3DVision. But generally, ULMB and LightBoost is otherwise very nearly identical but not the same overdrive/picture settings (LIghtBoost uses a slightly different overdrive algorithm -- LightBoost has lower contrast / lower dynamic range in order to improve overdrive to reduce strobe crosstalk). So it may be an unadvertised feature.
Also, it's possible to co-opt ULMB (combined with an emitter emulator) to be the 3D Vision strobe backlight. So even if LightBoost (Might be worth a try in the IPS / VA ones... I haven't heard of anyone successfully doing 3D Vision on those)
