We subjected the Xiaomi 12T to our rigorous SBMARK Display test suite to measure its performance Cons six criteria. In the results of this test, we will analyze how it fared in a variety of tests and several common use cases.
Overview
Main display specifications:
- 6.67 inches AMOLED, (~ 87.4% screen-to-body ratio)
- Dimensions: 163.1 x 75.9 x 8.6mm (6.42 x 2.99 x 0.34 inches)
- Resolution: 1220 x 2712 pixels, (density ~ 446 ppi)
- Aspect Ratio: 20: 9
- Refresh rate: 120Hz
Pros
- Fluid interactions in most uses
- Smooth light transitions
- Uniform screen color and brightness
versus
- Hardly legible in sunlight
- Inaccurate tone mapping makes HDR10 video content appear dark
- It shows a lot of ghost touches
The Xiaomi 12T’s display provided a smooth experience in most uses. The color and brightness were uniform and the adaptation of the screen to the light transitions was smooth. The readability of the display, however, was compromised in bright sunlight, making it difficult to read the contents. HDR videos also seemed to lack brightness on the screen.
However, the display performance of the Xiaomi 12T was an improvement over its predecessor, the Xiaomi 11T. The 12T’s display provided excellent fluidity, particularly when browsing the web and viewing the photo gallery. Our testers noticed an improvement over the 11T in color rendering and white point management. The artifacts on the 12T were well handled, especially the flickering and touch performance of the display was quite good.
However, readability on the 12T was not as good as on the 11T, even though the 12T’s score was over 10 points higher than the 12T Pro version. Xiaomi’s website claims that the 12T’s display can reach a maximum of 900 nits. , but we measured brightness up to 990 nits in sunlight.
The 12T’s display tone mapping, however, gave the impression of reduced screen brightness when watching HDR10 video, compared to the 11T.
Overall, the high-end segmented 12T, equipped with MediaTek’s Dimensity 8100 Ultra chipset, managed to outperform the Premium segmented 12T Pro, which is equipped with Qualcomm’s Snapdragon 8+ (Gen1) processor. This was also the case last year, when the 11T even surpassed the 11T Pro version.
Test summary
Learn about SBMARK visualization tests: For scoring and analysis in our smartphone and other display reviews, SBMARK engineers perform a series of objective and perceptual tests in controlled laboratory and under real-life conditions. Please note that we evaluate display attributes using only the device’s built-in display hardware and related still image (gallery) and video apps with default settings. (For in-depth information on how we rate smartphones and other displays, see our articles, “How SBMARK Tests Display Quality” and “A Closer Look at SBMARK Display Tests”.
The following section collects the key elements of our exhaustive tests and analyzes performed in SBMARK laboratories. Detailed performance evaluations in the form of reports are available upon request. Do not hesitate to contact us.
How the screen readability score is composed
Readability evaluates the ease and comfort with which users can read stationary content (photos and web) on the display in various real-life conditions. SBMARK 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 carried out in real-life environments.

The Xiaomi 12T Pro, on the left, shows significantly fewer details in sunlight than the 12T, on the right, in sunlight.
Measurement of luminance uniformity
This graph shows the uniformity of the display with a gray pattern of 20%. The more green the color is visible, the smoother the display.
How the Display Color score is composed
The color attribute evaluates the device’s ability to accurately reproduce colors. The measurements made are for fidelity, white point color and gamma coverage. We perform color assessments for different lighting conditions to see how well the device can handle color in its surroundings. Colors are measured using a spectrophotometer in a controlled lighting environment. The perceptual analysis of the color rendering is compared to the reference model displayed on a calibrated professional monitor.

Each arrow represents the color difference between a target color model (arrow base) and its actual measurement (arrowhead). The longer the arrow, the more visible the color difference. If the arrow stays inside the circle, the color difference will only be visible to trained eyes.
Behavior of the color on the corner
This graph shows the shift of color when the screen is tilted. Each point represents a measurement with a particular angle. The points inside the inner circle show no color change in the corner; those between the inner and outer circle have shifts that only trained experts will see; but those who fall outside the outer circle are noted.
How the Display Video score is composed
Our video attribute evaluates the Standard Dynamic Range (SDR) and High Dynamic Range (HDR10) video handling of each device indoors and in low light conditions. We measure the tone mapping, color gamut, brightness and contrast of the display. We perform perceptual analysis Cons our professional reference monitor (Sony BVM-HX310) to ensure that the rendering respects the artistic intent.

Range coverage for video content
Primary colors are measured in both 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 main color space of each video.
How the score of Display Motion is composed
The motion attribute evaluates the handling of dynamic content. Frame drops, motion blur, and playback artifacts are investigated using games and videos.
The video frame drops
These long exposure photos present the number of frame irregularities in a 30 second video. A good performance shows a regular pattern (a flat gray image or a drop-down pattern).
How the Display Touch score is composed
To evaluate touch, SBMARK uses a touch robot and a high-speed camera to reproduce and record a series of scenarios for the evaluation of fluidity, accuracy and response time.
This response time test accurately evaluates the time elapsed between a single tap of the robot on the screen and the action displayed. This test is applied to activities that require high responsiveness, such as play.
How the Display Artifacts score is composed
Evaluating artifacts means checking performance, image rendering, and motion defects that can affect the end-user experience. SBMARK accurately measures device reflectance and the presence of flickering and evaluates the impact of residual aliasing when playing video games, among other characteristics.
