28 November 2025, 10:32:31
ViewSonic has officially launched the XG323B-4K-OLED, a 31.5-inch OLED monitor boasting cutting-edge performance and versatility - combining 4K resolution with ultra-high refresh rates and a wealth of features aimed both at competitive gamers and content creators.
At the heart of the new monitor lies a 31.5-inch OLED display panel, supporting native 4K resolution (3840 × 2160 px) at up to 165 Hz - but that's not all. Users can switch via a single button to a Full-HD (1920 × 1080 px) mode running at a blistering 330 Hz refresh rate, ideal for high-speed competitive shooters where frame-rate and responsiveness matter most. The monitor responds with a lightning-fast 0.03 ms (GtG) response time, ensuring motion remains crisp and blur-free even in fast-paced games. On the gaming front, the monitor is compatible with FreeSync & G-Sync, and offers additional gamer-oriented features like customizable crosshairs, esports-style lighting effects, and support for PIP/PBP.
Thanks to the OLED panel, the XG323B-4K-OLED delivers a static contrast ratio of 1,500,000:1 (typical), producing deep blacks and high dynamic range. For HDR content, the monitor achieves a peak brightness of 1300 cd/m², and conforms to the DisplayHDR True Black 400 standard - a specification that underscores its capability to render dark scenes with rich depth while preserving highlight detail. Color reproduction is equally impressive: the display supports native 10-bit color depth, rendering over 1.07 billion colors, and covers 98.5% of DCI-P3 color gamut - delivering vivid, accurate colors for games, movies, and creative work.
The XG323B-4K-OLED offers two HDMI 2.1 ports, two DisplayPort 1.4 inputs, and a headphone jack. There's a USB Type-A port for upgrades only. It is fitted with a fully ergonomic stand for up to 130 mm og height adjustment, a bi-directional pivot, +/-45 degrees of swivel, and -5 to 20 degrees of tilt.
