Pros

  • Well-managed color rendering in indoor conditions
  • Smooth display when scrolling on the web
  • Fast response time when playing video games

Cons

  • Hardly visible dark shades when watching HDR10 videos
  • Frequent ghost touches
  • Unnatural image adaptation in outdoor conditions

The Xiaomi 12S Ultra’s display experience was average for an Ultra-premium device.

The display was fine for viewing photos in indoor conditions, with the screen delivering good color rendering. However, outdoors under sunlight, the color rendering was very unnatural.

Viewing HDR10 content was somewhat bothersome because of the screen’s inaccurate tone mapping and low brightness.

The highlight of the display experience on the Xiaomi 12S Ultra was surfing the web because of its smooth interactions and its 120 Hz refresh rate.

Test summary

About DXOMARK Display tests: For scoring and analysis in our smartphone and other display reviews, DXOMARK engineers perform a variety of objective and perceptual tests under controlled lab and real-life conditions. Note that we evaluate display attributes using only the device’s built-in display hardware and its still image (gallery) and video apps at their default settings. (For in-depth information about how we evaluate smartphone and other displays, check out our articles, “How DXOMARK tests display quality” and “A closer look at DXOMARK Display testing.

The following section gathers key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Detailed performance evaluations under the form of reports are available upon request. Do not hesitate to contact us.

Readability

How Display Readability score is composed

Readability evaluates how easily and comfortably users can read still content (photos & web) on the display under different real-life conditions. DXOMARK uses its Display Bench to recreate ambient light conditions ranging from total darkness to bright sunlight. In addition to laboratory tests, perceptual analysis is also made in real-life environments.

Luminance uniformity measurement

This graph shows the uniformity of the display with a 20% gray pattern. The more visible the green color, the more uniform the display.

How Display Color score is composed

The color attribute evaluates the capacity of the device to accurately reproduce colors. The measurements taken are for fidelity, white point color, and gamut coverage. We perform color evaluations for different lighting conditions to see how well the device can manage color in the surrounding environment. Colors are measured using a spectrophotometer in a controlled lighting environment. Perceptual analysis of color rendering is against the reference pattern displayed on a calibrated professional monitor.

Color fidelity measurements

Each arrow represents the color difference between a target color pattern (base of the arrow) and its actual measurement (tip of the arrow). The longer the arrow, the more visible the color difference is. If the arrow stays within the circle, the color difference will be visible only to trained eyes.
Color behavior on angle
This graph shows the color shift when the screen is at an angle. Each dot represents a measurement at a particular angle. Dots inside the inner circle exhibit no color shift in angle; those between the inner and outer circle have shifts that only trained experts will see; but those falling outside the outer circle are noticeable.

How Display Video score is composed

Our video attribute evaluates the Standard Dynamic Range (SDR) and High Dynamic Range (HDR10) video handling of each device in indoor and low-light conditions. We measure tone mapping, color gamut, brightness and contrast of the display. We perform perceptual analysis against our professional reference monitor (Sony BVM-HX310) to ensure that the rendering respects the artistic intent.

Gamut coverage for video content
HDR10 Gamut coverage
SDR Gamut coverage
The primary colors are measured both in HDR10 and SDR. The extracted color gamut shows the extent of the color area that the device can render. To respect the artistic intent, the measured gamut should match the master color space of each video.

Motion

How Display Motion score is composed

The motion attribute evaluates the handling of dynamic contents. Frame drops, motion blur, and playback artifacts are scrutinized using games and videos.


Video frame drops
30 fps content
60 fps content
These long exposure photos present the number of frame irregularities in a 30-second video. A good performance shows a regular pattern (either a flat gray image or a pull-down pattern).

How Display Touch score is composed

To evaluate touch, DXOMARK uses a touch robot and a high-speed camera to play and record a set of scenarios for smoothness, accuracy and response-time evaluation.

Average Touch Response Time Xiaomi 12S Ultra

How Display Artifacts score is composed

Evaluating artifacts means checking for the performance, image rendering and motion flaws that can affect the end-user experience. DXOMARK measures precisely the device’s reflectance and the presence of flicker, and assesses the impact of residual aliasing when playing video games, among other characteristics.
