Display
When you open the laptop, you will be greeted with a 14-inch OLED screen. Here’s a simpler and more refined version: The display design is the same as the previous generation, featuring ultra-thin bezels on three sides. The bottom bezel is slightly thicker and has the ROG Zephyrus branding, making it a little more noticeable. The screen has the following specifications:
- 14-inch OLED Display
- 8K (2880 x 1800) Resolution
- 120Hz Refresh Rate
- 16:10 Aspect Ratio
- 1100nits Peak Brightness
- 100% DCI-P3 Color Gamut Coverage
Before discussing the display further, it is worth noting that the display uses the Corning Gorilla Glass DXC anti-reflective coating. Compared to a standard glass-covered OLED panel, this coating can reduce reflections by up to 65%. Even when the screen was placed directly under a bright light source, reflections were greatly reduced, making the display easier to see in outdoor conditions.
The 14-inch OLED display features a 2.8K resolution and supports a 120Hz refresh rate, making it suitable for gaming, content creation, and daily productivity. The panel provides excellent sharpness, vibrant colors, and deep blacks typical of OLED technology.
The display is Samsung’s E6 OLED panel, providing improvements in both brightness and power efficiency compared to previous generations. According to official sources, the display supports up to 1100 nits in HDR mode, covers 100% of the DCI-P3 color gamut, and comes with factory color calibration, enabling it to deliver highly accurate colors right out of the box.
ASUS has also included multiple color profiles (including sRGB, Display P3, and DCI-P3), which users can switch through the Armoury Crate software, depending on the user’s workflow. This flexibility makes the laptop equally suitable for professional photo editing, video editing, graphic design, and general multimedia consumption.
Motion handling is equally impressive thanks to the 120Hz refresh rate, which provides smoother animations throughout Windows and a noticeably more seamless gaming experience compared to a traditional 60Hz display. Combined with OLED’s near-instant pixel response times (i.e., 0.2ms), fast-moving scenes remain exceptionally sharp with minimal motion blur.
We also did a benchmark test for the display, mentioned below:
