The Acer Predator XB273U F5 is a high-end gaming monitor featuring a 27-inch IPS panel, QHD resolution (which means 2560 x 1440 pixels), and an impressive 360 Hz refresh rate. This refresh rate allows for smoother motion and is particularly beneficial in fast-paced games. One of its standout features is the inclusion of **G-SYNC Pulsar**, a technology developed by NVIDIA to reduce motion blur while maintaining variable refresh rate (VRR), a feature that helps synchronize the display with the graphics card to prevent screen tearing. The monitor includes two HDMI ports, a DisplayPort, and a USB hub with three USB 3.2 ports. It also supports height adjustment, tilt, swivel, and portrait mode, with a VESA 100 × 100 mm mount for wall mounting or use with a stand. Acer is one of four manufacturers, alongside AOC, ASUS, and MSI, to introduce monitors with G-SYNC Pulsar. This technology aims to improve upon traditional strobing backlight systems by using progressive backlight scanning, which ensures that only the necessary parts of the screen are lit up at any given time. It also includes compensation pulses for varying refresh rates and variable overdrive, which helps reduce motion blur. In factory settings, the monitor has a color temperature of approximately 6,413 K, a gamma of 2.175, and a Delta E of 1.6 on the grayscale, which indicates how accurately it reproduces colors. The average Delta E for standard dynamic range (SDR) color measurement is 2.09, with a maximum of 4.15. The monitor's brightness is measured at 498 cd/m², with a contrast ratio of 984:1. During testing, the monitor's performance with G-SYNC Pulsar was evaluated in several games, including Counter-Strike 2, Apex Legends, Black Myth: Wukong, and Anno 117: Pax Romana. The user found that the technology improved readability during fast movements, especially at 120 Hz, although the improvement was less noticeable in slower-paced games. The monitor's brightness did not significantly decrease when Pulsar was activated, with only a minor increase in brightness observed. However, a slight flicker was detected when the refresh rate approached 75 Hz, indicating that the technology may have a lower operational limit at that point. The monitor's HDR performance was described as clean and well-maintained, with an average Delta E of 0.9 and a maximum of 2.35, indicating good color accuracy. However, the native contrast of the IPS panel limited its ability to match the performance of OLED monitors in dark scenes. The user concluded that while G-SYNC Pulsar enhances motion clarity, it does not make the IPS panel perform like an OLED panel. The monitor's price, nearly 700 euros, places it in a competitive market with QHD OLED screens, which offer superior contrast and black levels. Despite its limitations in color space coverage and HDR depth, the Acer Predator XB273U F5 provides a high brightness level, good factory settings, and improved motion clarity with Pulsar, making it a viable option for competitive gaming.
