Product Details
ROG Zephyrus Duo GX651 Intel Core Ultra 9 Processor 386H 2.1 GHz NPU up to 50TOPS Windows 11 Pro
The defining feature of the Zephyrus Duo isn’t visible at first glance. Unfold the machine for the first time, and you see a standard thin and light laptop with a gorgeous 3K ROG Nebula HDR Display OLED touch panel. But hiding just out of view under the magnetic keyboard cover is another full-size OLED. Our engineers have managed to hide a complete dual-screen battle station in a 16-inch laptop form factor, letting you maximize productivity and screen real estate wherever you go.
These panels are truly incredible. Each OLED panel is both ROG Nebula HDR and VESA Display HDR True Black 1000 certified, capable of up to 1100 nits of peak brightness for stunning HDR performance in games and your favorite video content. Both panels are extra tall with a 16:10 aspect ratio to further maximize screen real estate, and offer a 120Hz refresh rate for smooth scrolling. The main panel also supports G-SYNC, ensuring you won’t deal with screen tearing in game.
With a 1,000,000:1 contrast ratio, 100% coverage of the DCI-P3 color space, and color accuracy of Delta E<1, the Zephyrus Duo is ready out of the box for anything, from professional video and photography workflows to stunningly vibrant gameplay.
Modern OLED displays have significantly more resistance to burn in than in the past, but we’ve taken every step possible to keep these screens looking stellar for years to come. Image persistence, or burn-in, on an OLED display can occur if a static high-contrast image is displayed for a prolonged period of time (like the task bar or a HUD in most games). To avoid this, ROG OLED laptops come equipped with OLED Care and Pixel Shift technology, which moves displayed pixels slightly to avoid consistently showing static images on your desktop and reduces the chance of burn-in
