Display Type and Size

With a resolution of 3200 x 1440 pixels (WQHD+), the S21 Ultra delivers crystal-clear images and text. The high pixel density ensures that even the smallest details are sharp and well-defined.

Adaptive Refresh Rate

A standout feature is the adaptive refresh rate, which can dynamically adjust between 10Hz and 120Hz. This feature intelligently adapts to your on-screen content:

  • Lower Refresh Rate: For static content like reading, the display lowers the refresh rate, conserving battery life.
  • Higher Refresh Rate: For fast-paced action like gaming or scrolling, the display ramps up to provide a smooth, fluid experience.


The S21 Ultra display can reach a peak brightness of 1500 nits. This level of brightness guarantees excellent visibility even in harsh sunlight.

HDR10+ Support

The display supports HDR10+, offering an enhanced dynamic range with better contrast and more vivid colors in HDR-compatible content.

Unraveling the Display Specifications

At the heart of the S21 Ultra’s appeal is its large, vivid display. Boasting a 6.8-inch screen measured diagonally, the S21 Ultra offers an expansive viewing area. This screen isn’t just large; it’s also incredibly detailed, with a resolution of 3200 x 1440 pixels. This QHD+ resolution ensures that everything you view is crisp and full of detail. The screen has a 20:9 aspect ratio, making it slightly longer and more slender than a typical smartphone screen. This aspect ratio is great for watching videos or browsing the web, as it provides more screen real estate. Furthermore, with a pixel density of 515 ppi, the S21 Ultra’s display is remarkably sharp, making text and images appear smooth and clear​​.

Dynamic AMOLED 2X: The Visual Powerhouse

The Galaxy S21 Ultra features a Dynamic AMOLED 2X screen. This technology is a step up from the traditional AMOLED displays, offering brighter colors and deeper blacks. The “2X” in its name refers to the display’s ability to offer twice the dynamic range of a standard AMOLED screen. This means you get a display that’s not only bright but also capable of showing a wide range of colors and contrasts. This makes for an incredibly immersive viewing experience, whether you’re watching movies, playing games, or just scrolling through your social media feed​​.

120Hz Refresh Rate: Smooth as Silk

One of the most talked-about features of the S21 Ultra’s display is its 120Hz refresh rate. This high refresh rate means the screen updates its image 120 times per second, which is twice as often as the standard 60Hz screens found on many smartphones. This results in exceptionally smooth motion, which is particularly noticeable when scrolling through content or playing fast-paced games. Moreover, the S21 Ultra allows you to run the screen at its native 1440 x 3200 resolution at this 120Hz refresh rate, a capability that was not available in its predecessors​​.

HDR10+ and Brightness: Bringing Life to Images

HDR10+ support is another feather in the cap of the S21 Ultra’s display. This technology enhances the viewing experience by offering higher contrast and a wider range of colors. It makes the images on your screen look more lifelike and dynamic, especially when viewing HDR content. In terms of brightness, the S21 Ultra’s display can reach peak levels of 1016 nits. This high brightness level ensures that the screen remains visible even under direct sunlight, making it ideal for outdoor use​​​​.

Always-On Display: Convenience at a Glance

The Always-On Display feature on the S21 Ultra is a nifty addition that allows you to see key information at a glance without having to wake up the phone. This feature shows time, date, notifications, and other useful information on the screen when it’s in a locked state. It’s a great way to quickly check your phone without having to fully activate the display, saving both time and battery life.

Innovations and Enhancements: A Step Ahead

Samsung has continuously innovated with its display technology, and the S21 Ultra is no exception. The ability to combine a high resolution with a high refresh rate in the same device is a significant achievement. This combination offers the best of both worlds – sharp, detailed images with smooth motion. The near bezel-less design with rounded corners and a minimal camera hole further enhances the aesthetic appeal of the device, making the display appear even more expansive.
