G-sync Pulsar Firmware Update 1.1.6
G-SYNC Pulsar is NVIDIA’s latest variable refresh backlight strobing technology. It combines variable refresh rate support with motion clarity features that normally require a fixed refresh rate. The goal is to reduce motion blur while keeping the smoother frame pacing of G-SYNC.
Unlike older ULMB modes, Pulsar can operate across a wider FPS range. It adjusts strobing behavior based on the game’s frame rate, which is why NVIDIA’s firmware notes mention fixes for specific FPS ranges such as 100 to 180 FPS and below 90 FPS.

NVIDIA has a firmware update
In case you are confused why it’s NVIDIA releasing updates, G-SYNC Pulsar depends on the G-SYNC module and NVIDIA’s display processing stack. Monitor vendors such as AOC, MSI, Acer, and ASUS ship the hardware, but the Pulsar behavior is controlled by NVIDIA firmware. This is why firmware updates are distributed through NVIDIA’s G-SYNC monitor update page rather than only through each monitor maker’s support site.
For users, version 1.1.6 improves Pulsar behavior in the 100 to 180 FPS range and fixes several display handling issues, including EDID white-point reporting, input switching, cable detection with DP80 cables, and frame skipping when a second input is active.
- 1.1.6
- Improved G-SYNC Pulsar operation for 100 – 180 FPS range.
- Fixed monitor white-point value in EDID to D65 white-point value.
- Fixed input auto-switch issue.
- Fixed cable detection issue affecting input switching when using a DP80 cable.
- Fixed occasional frame skip issue when second input is active.
- 1.1.4
- G-SYNC Pulsar optimizations
- Eliminated sharp double images when operating under 90 FPS
- In-monitor FPS indicator now works correctly below 90 FPS
- Added a fixed ULMB2 60 Hz strobing mode (for games locked to 60Hz)
NVIDIA says version 1.1.6 is currently available only for the AOC AGON PRO AG276QSG2 and MSI MPG 272QRF X36. Acer Predator XB273U F5 and ASUS ROG Strix Pulsar XG27AQNGV monitors remain on firmware 1.1.4 for now, with 1.1.6 support planned soon.
