Key display specifications:

  • 6.7 inches AMOLED Dynamic 2X, (~86.9% screen-to-body ratio)
  • Dimensions: 84.9 x 71.9 x 15.9 mm (3.34 x 2.83 x 0.63 inches)
  • Resolution: 1080 x 2640 pixels, (~426 ppi density)
  • Aspect ratio: 22:9
  • Refresh rate: 120 Hz


Sub-scores and attributes included in the calculations of the global score.

  • A good performance for HDR10 video content, thanks to suitable brightness and good color fidelity
  • Good smoothness in every use case
  • Overall color performance is good.


  • Under sunlight the high brightness mode gives an unnatural aspect to colorful content
  • Brightness is too high for comfortable reading at night when the blue light filter is off.
  • Picture details are hard to read when viewed in indoor conditions.

Like the Z Flip3 5G, the Z Flip4’s crease is visible. And as with Samsung Galaxy S22-series phones, the Z Flip4 boosts its colors under sunlight, with the result that color content appears flat and unnatural. Apart from sunlight, the Z Flip4 puts in a good color performance in all other tested ambient lighting. The Z Flip4 has a very stable angular performance in color, meaning that the color differences of both sides of the screen are minimized; you will see a difference only at important angles.

While readability is generally quite good, darker details in pictures are hard to see when viewed in indoor conditions, and the screen can be uncomfortably bright when reading at night without using the blue light filter.

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.

Luminance uniformity measurement

This graph shows the uniformity of the display with a 20% gray pattern. The more visible the green color, the more uniform the display.

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.

Color fidelity measurements

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 Z Flip4

This response time test evaluates precisely 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 a 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 Z Flip4

Reflectance measurement (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.

Flicker comparison

This graph represents the frequencies of lighting variation; the highest peak gives the main flicker frequency.

The Z Flip4’s low artifacts score is not only due to its flicker and visible crease, but because of its behavior when viewed through polarized sunglasses, as shown below.
