Pros

  • Good readability under sunlight thanks to a very high peak brightness
  • Accurate color rendering in most lighting environments
  • Excellent management of frame mismatches when watching  videos or playing video games

Cons

  • Excessively high brightness levels in HDR video playback
  • Lack of brightness and details in indoor lighting environment
  • Poor management of involuntary touches

The Samsung Galaxy S24 nearly matched the display performance of the top-of-the-line S24 Ultra, thanks to achieving two top scores in readability and touch, but the smaller device was held back due to its management of artifacts.

Even though the devices have key differences, mainly in size, chipset, and glass, the Galaxy S24’s display behavior was very similar to that of the Ultra version. The 6.2-inch S24, like the 6.7-inch S24+, was released with the latest version of  Samsung’s in-house chip, Exynos 2400, while the 6.8-inch S24 Ultra sports Qualcomm’s Snapdragon 8 Gen 3. The S24’s glass protection is the same as the one used on the S23 series, whereas the S24 Ultra’s display has glass reinforced with anti-reflective properties, which played a role in artifacts management.

While the lack of an anti-reflective screen cost the S24 significant points in artifacts, due to poor reflection management, it could also be said that the older glass was a contributing factor in S24 attaining a top score in readability. When it came to luminance, the S24 achieved a slightly higher peak than the already-impressive peak of the S24 Ultra, making the S24 a very readable screen in sunlight. Peak brightness, better gamma management under sunlight, and a more uniform screen all helped the device achieve a top score in the readability attribute.

In our display evaluation, our testers found the S24’s screen colors to be a huge improvement over the predecessor S23. The colors on the S24 were much more accurate than on previous S-series models, particularly outdoors, correcting the color artifact noticed on the S23 series. The S24 series’ new type of color signature, with the same color rendering across all three models, offers much more of a “natural” rendering compared to the previous series. However, when viewing the S24 screen on an angle, screen colors did change, but not as much as they did on the S24 Ultra, a factor that helped the S24 achieve a slightly better score in the color attribute.

An overly bright screen can make watching videos in a dark environment quite uncomfortable if the device does not sufficiently decrease brightness. In our tests, the S24’s screen, like on the S24 Ultra, lost some points here for remaining much too bright when viewing videos.

In the motion attribute, stutter was visible when resuming the video in playback, showing that the S24 was a bit slower than the S24 Ultra in execution.

The S24 reached a top score for its touch interactions, which were accurate and smooth, with a fast response time.

The S24’s impressive display performance earned it the top spot so far among devices in the Premium segment.

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.

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.

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.

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

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

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 Samsung Galaxy S24

This response time test precisely evaluates the time elapsed between a single touch of the robot on the screen and the displayed action. This test is applied to activities that require high reactivity, such as gaming.

Artifacts

Samsung Galaxy S24

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.

Average Reflectance (SCI) Samsung Galaxy S24

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.
Reflectance (SCI)
Measurements above show the reflection of the device within the visible spectrum range (400 nm to 700 nm). It includes both diffuse and specular reflection.

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 main flicker frequency. The combination of a low frequency and a high peak is susceptible to inducing eye fatigue. Displays flicker for 2 main reasons: refresh rate and Pulse Width Modulation. 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 safer for users.
