Gsync Pulsar: Nvidia's strobe-based approach to clearer motion

Nvidia unveiled Gsync Pulsar at CES 2026 as a firmware-driven version of Gsync that uses strobe backlighting to simulate much higher refresh rates, which Nvidia says can reach up to 1,000Hz. Gaming monitors with Gsync Pulsar are scheduled to begin shipping in the coming week, with reviewers planning hands-on tests.

Nvidia introduced Gsync Pulsar at CES 2026 as a new, firmware-based form of its Gsync display technology. The system pairs variable refresh behavior with strobe backlighting to create the impression of much higher refresh rates. Gsync originally launched in 2013 to eliminate screen tearing by matching refresh rate to frame rate, and variable refresh support has since become widespread across monitors and TVs. The Pulsar approach is intended to improve motion clarity rather than reduce input latency. What is known: - Gsync Pulsar requires special firmware and was shown by Nvidia at CES 2026. - The system uses strobing backlights to simulate higher refresh rates; Nvidia states it can simulate up to 1,000Hz. - The technology is designed to improve perceived motion clarity and is not described as reducing latency or responsiveness. - Nvidia worked with Mediatek on a new Gsync module that can control the backlight to speed up or slow down with the display refresh rate. - By default, Pulsar disables itself when refresh rate and frame rate fall below 90Hz; users can lower the limit to 75Hz, and Nvidia reported it is exploring 60Hz support. - According to the article, gaming monitors with Gsync Pulsar are poised to reach the market within about a week, and reviewers plan further lab testing. Summary: Reportedly, Pulsar pairs variable refresh with controlled strobing to make fast motion appear clearer without claiming latency improvements. It has built-in limits designed to avoid visible strobing at low frame rates, and its real-world behavior at variable, lower frame rates remains to be examined. Monitors with the feature are expected to arrive shortly, and additional reviewer tests are anticipated to report on performance in typical gameplay.
