What Is G-SYNC Pulsar and How Does It Differ From Regular G-SYNC?
In a bid to improve fidelity and motion, NVIDIA is continually pushing the envelope when it comes to gaming monitor technology. G-SYNC Pulsar is the next step towards a tear-free and smooth gaming experience from the market-leading GPU manufacturer. Here's how it works.
What Is G-SYNC Pulsar?
G-SYNC, a variable refresh rate (VRR) technology from NVIDIA, eliminates screen tearing and allows for a better motion experience. G-SYNC Pulsar marries G-SYNC with Ultra Low Motion Blur (ULMB) to create a silky smooth gaming experience that also includes unprecedented motion clarity.
G-SYNC Pulsar allows for NVIDIA's ULMB tech, NVIDIA's name for backlight strobing, to work in combination with VRR without image flicker or other downsides.
Why Is G-SYNC Pulsar Necessary?
ULMB tech, also known as backlight strobing, turns off the monitor backlight in between new frames to eliminate a type of motion blur caused by the image persistence on our retinas. This occurs when we track fast-moving objects and during sudden camera movements, and is also known as sample and hold motion blur.
This type of motion blur is found on most monitors and TVs, which keep showing the current frame right until the next frame is shown. This results in perceived motion blur, even on panels with near instantaneous response time, such as OLED panels.
ULMB, as well as similar technologies such as black frame insertion (BFI), which is especially effective on OLED TVs and monitors, work pretty well, but they all require the monitor or the TV to work at a fixed refresh rate. Despite this some monitors allow you to enable backlight strobing simultaneously with VRR, which usually results in severe flickering.
In most cases, on a monitor that supports both G-SYNC and ULMB, you usually have two choices. The first is to turn on ULMB and get crystal clear motion but with increased latency and screen tearing inherent to fixed refresh rate mode. The other option is to opt for G-SYNC alone and get silky smooth
