Nvidia G-SYNC ULMB 2 released
G-SYNC ULMB 2 offers an effective motion sharpness rate of over 1000 Hz that will make a big difference in competitive gaming and eSports games. With its ULMB 2 technology, Nvidia hopes to improve the appearance of motion when there is permanent blur, offering close to 2x the brightness and zero noise. ULMB 2 is currently available for free for 1440p 360Hz G-SYNC monitors via a firmware update.
When the original ULMB technology was introduced in 2015, monitor response times (the time it takes for a pixel to color transition) were relatively slow, causing significant ghosting and blurry images, resulting in poor motion sharpness. Nvidia has developed a technique called “backlight strobing” for this. To use this technique, ULMB would disable the backlight 75 percent of the time. So images were clearer on a typical 300 nits panel, but the brightness was also reduced.
