Pros

  • Smooth display experience when scrolling the web
  • Adapted brightness in low-light conditions for photo and web
  • Pleasing color rendering in indoor conditions for photo

Cons

  • Many frame mismatches when watching videos
  • Lack of brightness and details in indoor lighting environment when looking at photos
  • Lack of brightness and dark details when watching HDR10 videos
  • Display is not uniform

The Xiaomi 14 had a mixed display performance in our tests, although it offered a very smooth screen experience in all use cases, with a steady performance in the touch and video attributes.

The device’s best-scoring attribute was touch, thanks to an impressive average touch to display response time of 64 ms.

Although the Xiaomi 14 provided an acceptable performance in video, the device’s overall video performance was affected by some instabilities. When watching HDR10 videos in indoor conditions, the screen lacked sufficient brightness and showed few details in dark tones, particularly in low light. In addition, HDR10 frame-drop management was poor.

In readability, the Xiaomi 14 screen managed its brightness well, particularly in low-light conditions, however, it might fall a bit short on readability for intense lighting conditions. Xiaomi says that the device can reach a peak brightness of 3000 nits, but our tests showed the device reaching 2740 nits — but only for HDR video content. Our experts measured 923 nits under 20,000 lux and only 1490 nits under sunlight on a classic (20% window) white image pattern in High Brightness Mode, results that were lower than some competitors in this segment. Readability, however, was affected by the screen’s low-frequency temporal management in default mode (but the device has an anti-flicker feature that can limit this phenomenon.) The Xiaomi 14’s screen also lacked uniformity in brightness and color.

The Xiaomi 14’s colors were quite good in most lighting conditions when viewing photos, but when tested in faithful mode, the screen’s color rendering could appear to be slightly saturated.

Test summary

About DXOMARK Display tests: For scoring and analysis, a device undergoes a series of objective and perceptual tests in controlled lab and real-life conditions. The DXOMARK Display score takes into account the overall user experience the screen provides, considering the hardware capacity and the software tuning. In testing, only factory-installed video and photo apps are used.  More in-depth details about how DXOMARK tests displays are available in the article “A closer look at DXOMARK Display testing.”

The following section focuses on the key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Full reports with detailed performance evaluations are available upon request. To order a copy, please contact us.

How Display Readability score is composed

Readability evaluates the user’s ease and comfort of viewing still content, such as photos or a web page, on the display under different lighting conditions. Our measurements run in the labs are completed by perceptual testing and analysis.

Luminance under various lighting conditions
This graph shows the screen luminance in environments that range from total darkness to outdoor conditions. In our labs, the indoor environment (250 lux to 830 lux) simulates the artificial and natural lighting conditions commonly seen in homes (with medium diffusion); the outdoor environment (from 20,000 lux) replicates a situation with highly diffused light.
Contrast under various lighting conditions
This graph shows the screen’s contrast levels in lighting environments that range from total darkness to outdoor conditions. In our labs, the indoor environment (250 lux to 830 lux) simulates the artificial and natural lighting conditions commonly seen in homes (with medium diffusion); the outdoor environment (from 20,000 lux) replicates a situation with highly diffused light.
Photo EOTF
The Electro-Optical Transfer Function (EOTF) defines how bits are converted into luminance out of the display. Gray levels (horizontal axis) represent the different shades from pure white (100% gray level) to pitch black (0% gray level). The standard for still images follows a 2.2 gamma. The flatter the curves, the harder it is to perceive differences between consecutive shades. This phenomenon is more frequent under intensive lighting conditions (20,000 lux) in the low gray level regions.

SCI stands for Specular Component Included, which measures both the diffuse reflection and the specular reflection. Reflection from a simple glass sheet is around 4%, while it reaches about 6% for a plastic sheet. Although smartphones’ first surface is made of glass, their total reflection (without coating) is usually around 5% due to multiple reflections created by the complex optical stack.
Average reflectance is computed based on the spectral reflectance in the visible spectrum range (see graph below) and human spectral sensitivity.
Reflectance (SCI)
Wavelength (horizontal axis) defines light color, but also our capacity to see it; for example, UV is a very low wavelength that the human eye cannot see; Infrared is a high wavelength that the human eye also cannot see). White light is composed of all wavelengths between 400 nm and 700 nm, i.e. the range the human eye can see. Measurements above show the reflection of the devices within the visible spectrum range (400 nm to 700 nm).

Uniformity
This graph shows the distribution of luminance throughout the entire display panel. Uniformity is measured with a 20% gray pattern, with bright green indicating ideal luminance. An evenly spread-out bright green color on the screen indicates that the display’s brightness is uniform. Other colors indicate a loss of uniformity.

Displays flicker for 2 main reasons: refresh rate and Pulse Width Modulation. Pulse width modulation is a modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. This measurement is important for comfort because flickering at low frequencies can be perceived by some individuals, and in the most extreme cases, can induce seizures. Some experiments show that discomfort can appear at a higher frequency. A high PWM frequency (>1500 Hz) tends to be less disturbing for users.
Temporal Light Modulation
This graph represents the frequencies of lighting variation; the highest peak gives the most important modulation. The combination of a low frequency and a high peak is susceptible to inducing eye fatigue.

How Display Color score is composed

Color evaluations are performed in different lighting conditions to see how well the device manages color with the surrounding environment. Devices are tested with sRGB and Display-P3 image patterns. Both faithful mode and default mode are used for our evaluation. Our measurements run in the labs are completed by perceptual testing & analysis.
