Asus has unveiled its latest high-end gaming monitor, the ROG Swift OLED PG27UCWM, which is based on an all-new OLED panel that takes advantage of LG Display’s “4th Gen Tandem OLED” technology. This screen features an “RGB stripe” sub-pixel layout, which promises to deliver higher brightness and clarity compared to old 27-inch gaming monitors, while maintaining the original 4K resolution and an optional refresh rate of up to 480 Hz.
The PG27UCWM is considered the smallest screen that Asus is displaying this week in Las Vegas at the CES 2026 exhibition, as it comes in a size of 27 inches and has specifications worthy of the high-end “ROG Swift” series. Thanks to Tandem OLED technology, the screen supports “Dual Mode” mode, which allows users to switch between 4K resolution with a refresh rate of 240 Hz or 1080p resolution with a super refresh rate of 480 Hz.
The “RGB Stripe” sub-pixel layout is an important turning point, as it theoretically helps significantly improve text clarity compared to old OLED screens that suffered from problems in this aspect. The screen comes with a pixel density of about 166 PPI, which enhances the display resolution. The screen also features an ultra-fast response time of 0.03 ms (gray to gray), support for variable refresh rate (VRR) technologies, and VESA DisplayHDR 500 True Black certification that guarantees a brightness of up to 0.03 ms (gray to gray). Up to 500 nits in SDR mode.
In terms of connectivity, Asus has provided the screen with advanced ports that include DisplayPort 2.1 (UHBR20), HDMI 2.1, and a USB Type-C port that supports 90-watt power delivery. While the company has not yet announced the official availability date or price, expectations indicate its global launch during the first half of 2026.
