Pros

  • Good color fidelity and suitable brightness for HDR10 video content
  • Good readability in all tested lighting conditions
  • Smooth in most usages

Cons

  • Under sunlight, the high brightness mode gives an unnatural aspect to color content
  • The crease is visible in most situations

The Samsung Galaxy Z Fold5 provided a decent display performance, demonstrating strong showings in video and color under the updated protocol.

Good readability under sunlight is rare among ultra-premium devices, yet the Z Fold5 achieved good contrast on content viewed even in bright outdoor conditions. Our engineers measured the device’s peak brightness at 1682 nits under bright sunlight. Only slightly detracting from its all-round excellent performance, the Z Fold5’s screen was highly reflective.

The Samsung Galaxy Z Fold5 provided a wide color gamut in its default “Vivid” mode, resulting in pleasant and saturated colors in low light and indoor conditions. When in direct sunlight outdoors, the device’s high brightness mode made some colorful content look slightly desaturated and flat in “Vivid” mode. When tested in the protocol’s natural mode setting, color rendering was faithful, comfortable and pleasant, in most lighting conditions, except under sunlight.

As is typical of many Samsung devices, the Z Fold5’s brightness, colors, and detail rendering make it a good device for watching HDR10 videos in both low-light and indoor conditions.

A recurring issue with many foldable screens is the visibility of a crease when the screen is unfolded. The Z Fold5’s crease was visible in every condition, especially outdoors; and as with other foldable phones, the device was affected by a jello effect — a slight perceptible lag between the right and left sides of the display that can make content appear a bit “bent.” But our engineers observed no frame mismatches when evaluating the Z Fold5 while watching videos.

Its brightness, color, and detail rendering make it a great choice for watching videos. Accurate and reactive, the device felt smooth when browsing the web, and scrolling in the gallery, but sometimes it was prone to reacting to unwanted touches.

Note that DXOMARK tested the Z Fold5’s main screen with its protective screen on, per Samsung’s recommendation to consumers.

Exceptionally, our engineers also measured the peak brightness and reflectance of the Z Fold5’s cover screen, which is not part of the protocol and did not factor into the device’s scoring. The Z Fold5’s cover screen achieved peak brightness at 1710 nits and had the same color gamut as the main screen; moreover, the cover screen was less reflective than the main screen (4.8% vs. 6.3%).

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).
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.
