Multiple models of BenQ gaming monitors have official AMD FreeSync implementation. That means FreeSync is guaranteed to work on those monitors, and is especially nice to have in high framerate models that go up to 144Hz. Once more, when we say guaranteed to work we mean with AMD Radeon graphics cards.
But what if you have a GeForce graphics card instead? Here enters the no harm in trying part. Because FreeSync and G-Sync are so similar and so closely related to VESA Adaptive Sync, FreeSync may very well work with your GeForce graphics card. You may not get the more premium aspects (variable refresh rate probably won’t work for HDR gaming content, for example), but the basic screen tearing prevention could operate just fine. You could try turning G-Sync on in the NVIDIA control center and see what happens.
The flip side of this holds true as well. If you have a G-Sync monitor and an AMD graphics card, G-Sync could still function at least on that basic level we mentioned. The hardware and software architecture of the two technologies is so similar, most graphics cards may overlook the difference. On a related note, neither AMD nor NVIDIA are actively blocking each other’s proprietary technologies, so that’s good.
We can say that FreeSync monitors are also “G-Sync possible”. Claiming G-Sync support or compatibility would be going too far. Rather, it would be more correct to explain that G-Sync is very possible on FreeSync displays, and vice versa.
