G-Sync
Definition
NVIDIA branding for variable refresh rate display technologies.
Detailed explanation
G-Sync is NVIDIA branding for variable refresh rate technologies that coordinate display refresh with GPU frame delivery. Some monitors contain a proprietary G-Sync module, while G-Sync Compatible displays use Adaptive-Sync behavior validated by NVIDIA. Display interface, monitor range, driver, and application presentation mode all participate. Variable refresh reduces tearing and judder by allowing the display to present frames when the GPU completes them within an operating range. Behavior below that range can use frame repetition, while behavior above it depends on presentation and synchronization settings outside the monitor module itself.
