NVIDIA’s firmware update (version 1.1.4) for G-SYNC Pulsar monitors fixes sharp double images and the in-monitor FPS indicator when running below 90 FPS, and adds a fixed 60Hz strobing mode for games capped at 60 FPS.

The update aims to reduce motion blur at low refresh rates, addressing a long-standing G-Sync Pulsar weakness for under-90 FPS gameplay.

Installation is browser-based and requires no extra software; users connect the monitor via cable and run the official web utility.

The process takes about 5 to 10 minutes and includes a built-in recovery to retry the update if something goes wrong.

The news is sourced from NVIDIA, with additional context from Wccftech.

Officially supported browsers are Chrome 61, Edge 79, and Opera 48; the utility works across Windows, macOS, Linux, Android, and ChromeOS, but not iOS.

The update relies on embedded Pulsar hardware within each monitor’s scaler chip and does not require a daughterboard.

This update underscores the value of updatable G-Sync Pulsar modules, enabling firmware improvements without replacing the monitor.

NVIDIA showcased G-Sync Pulsar at Computex 2025 and CES 2026, highlighting the goal of reducing object hold time by synchronizing backlight pulses with frame delivery.

The firmware supports models such as Acer Predator XB273U F5, AOC AGON PRO AG276QSG2, ASUS ROG Strix Pulsar XG27AQNGV, and MSI MPG 272QRF X36, with roll-back options to earlier versions.

G-Sync Pulsar blends VRR with Ultra Low Motion Blur for high perceived smoothness, though current adoption is limited to a select set of monitors.

Technically, backlight strobe is synchronized to frame delivery so pulses occur when frames are stable, minimizing motion smear.
