Pros
- Good readability under sunlight thanks to a very high peak brightness
- Improved management of screen reflections, thanks to advanced glass technology
- Accurate color rendering in most lighting environments
- Excellent management of frame mismatches when watching all types of videos or playing video games
Cons
- Excessively high brightness levels in video performance
- Lack of brightness and details in indoor lighting environment
- Poor management of involuntary touches
The Samsung Galaxy S24 Ultra’s screen performance earned the flagship device the overall top spot in our Display protocol ranking, thanks to the marked improvements in nearly all attributes, particularly over its predecessor the S23 Ultra.
In readability, the S24 Ultra was just shy of achieving the top score with its impressive performance in challenging environments. In our tests under bright sunlight, the device achieved a measured peak brightness of 2572 nits (close to the 2600 advertised), which is significantly above the Galaxy S23 Ultra’s 1750 nits. Moreover, the addition of an anti-reflective glass serves to deepen contrast to make the images more vivid in challenging conditions. These combined performances mean that in direct sunlight, it’s not necessary to find a shaded area or to cover the screen with one’s hand to be able to see and read what is on the display. While performance was great outdoors, the screen’s brightness could be a little imprecise in other conditions: our testing results showed that screen brightness sometimes could be too high at night and too low in indoor environments.
The Samsung Galaxy S24 Ultra’s color fidelity and rendering were much better than the S23 Ultra’s, particularly outdoors where the S24 Ultra corrected the lack of color shades of its predecessor, but still came in a bit behind the top score. Also, viewing the screen at an angle would show a slight shift to pink and green.
Motion performance garnered a top score for S24 Ultra because of the excellent way it managed frame mismatches when playing videos. Additionally, the display would adapt its refresh rate to that of the video frame rate, thus avoiding judder.
The S24 Ultra should have provided a very similar video experience as its predecessor, but that was not the case. The S24 Ultra was unable to achieve the S23 Ultra’s top-scoring performance in video mainly because the screen was too bright to view the content comfortably under a low-light environment.
The device’s redesigned edged display probably contributed to improvements over the S23 Ultra in terms of touch interactions and accuracy, although there were occasions of unintentional touches when playing video games. Scrolling the web and viewing the gallery were overall smooth experiences. Touch reactivity also quickened slightly over the S23 Ultra, which was already quite good.
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.

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.

Gamut coverage for video content
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.

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
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 Samsung Galaxy S24 Ultra
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.

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 Ultra
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.
