NVIDIA has pushed a new firmware update for G-SYNC Pulsar 360Hz monitors, and the biggest gains are aimed squarely at competitive players. The update lowers input lag in Pulsar and ULMB modes at 240Hz while also improving motion clarity, which is the area that matters most when fast-paced action needs to stay readable.
The change is especially notable because 240Hz is where NVIDIA says the improvement is most noticeable. For users who already rely on G-SYNC Pulsar for speed and image clarity, the new firmware is less about a minor tune-up and more about refining the core experience.
What NVIDIA changed in firmware 1.1.8
NVIDIA says the update arrives as firmware version 1.1.8 and is available for all compatible G-SYNC Pulsar 360Hz monitors. The company lists reduced input lag for 240Hz Pulsar and ULMB, along with improved ULMB 2 quality at 120Hz.
The update also adds a ULMB2 Pulse Width slider for MSI and AOC Pulsar models. NVIDIA further says the firmware fixes an issue where G-SYNC and Pulsar could disappear after the monitor entered sleep mode.
| Firmware 1.1.8 Change | Effect |
|---|---|
| Reduced input lag | Applies to 240Hz Pulsar/ULMB |
| ULMB2 Pulse Width slider | Added for MSI and AOC Pulsar models |
| Improved ULMB 2 quality | Applies at 120Hz |
| Sleep-mode fix | Restores G-SYNC and Pulsar availability after sleep |
A new backlight method powers the improvement
To reach the new results, NVIDIA changed how ULMB 2 works under the hood. The company moved from a Rolling Scan method to a Global Flash technique, which flashes the backlight briefly between refreshes instead of keeping it continuously lit.
That adjustment is designed to reduce motion blur further and improve the sharpness of moving objects. In practical terms, it should help players track targets more cleanly and keep outlines easier to follow during rapid camera movement.
Supported monitor models
The firmware update is available across the G-SYNC Pulsar 360Hz lineup, including the Acer Predator XB273U F5, AOC AGON PRO AG276QSG2, ASUS ROG STRIX Pulsar XG27AQNGV, and MSI MPG 272QRF X36. That broad support makes the update relevant across several monitor brands rather than a single ecosystem.
| Monitor Model | Brand | Availability |
|---|---|---|
| Predator XB273U F5 | Acer | Supported |
| AGON PRO AG276QSG2 | AOC | Supported |
| ROG STRIX Pulsar XG27AQNGV | ASUS | Supported |
| MPG 272QRF X36 | MSI | Supported |
Why this update matters for competitive users
G-SYNC Pulsar was built to combine extremely low latency with strong motion clarity, and NVIDIA has continued to refine it after launch. The firmware updates show that monitor performance can still improve after purchase, especially when the gains come from software and firmware rather than new hardware.
That matters for esports-focused users because every small change can affect responsiveness and readability in motion. With version 1.1.8, NVIDIA is targeting the parts of the experience that players notice most often, from cleaner movement to more stable feature behavior after sleep.
Users who want the update can visit NVIDIA’s G-SYNC Pulsar firmware update page and select “Update Monitor.” From there, the process continues by following the on-screen instructions provided on the page.
