ViewSonic's latest gaming monitor not only offers a 240 Hz QD-OLED panel with full 4K resolution and an HDR peak brightness of 1,000 nits, but also many useful features, including 100 watts of USB-C PD and relatively powerful stereo speakers.

ViewSonic's XG273-4K-OLED-2 is a new gaming monitor based on Samsung's 26.5-inch QD-OLED panel, featuring full 4K resolution and a refresh rate of 240 Hz. This panel is also used in the MSI MPG 272UR, among others. ViewSonic advertises a full-screen brightness of 250 nits and an HDR peak brightness of 1,000 nits.

In practice, peak brightness is unlikely to exceed 450 nits since the panel cannot go beyond this if an average illumination of 10% is exceeded. According to ViewSonic, the panel can display 99% of the DCI-P3 color space. With a response time of just 0.03 milliseconds and support for a variable frame rate that can be adjusted to the actual frame rate of a game, the screen is said to be ideal for gaming enthusiasts.
 


The ViewSonic XG273-4K-DLED-2 features two HDMI 2.1 ports, two DisplayPort 1.4 ports and a USB-C port that can charge connected laptops with up to 100 watts. The monitor features integrated 2 x 3-watt stereo speakers. The included stand allows the monitor to be adjusted in height by up to 12 centimeters, tilted, and rotated into portrait mode.

Price and availability

The ViewSonic XG273-4K-OLED-2 gaming monitor will initially be launched in China, where it will be available for 5,499 yuan (approximately $767). ViewSonic has not yet confirmed when or at what price the gaming monitor will be available globally.
