We put the Vivo X100 Pro through our rigorous SBMARK Display test suite to measure its performance across six criteria. In the results of this test, we will analyze how it performed in a series of tests and in several common use cases.

Overview

Key Display Specifications:

  • 6.78 inches AMOLED LTPO, 109.8 cm2 (screen-to-body ratio ~91.3%)
  • Resolution: 1260 x 2800 pixels, (density ~452 ppi)
  • Aspect ratio: 20:9
  • Refresh rate: 120Hz

Pros

  • Good HDR10 video experience, with well-managed brightness and details
  • Good color fidelity in indoor conditions

Against

  • Unnatural rendering of dark content in sunlight
  • Visible frame drops when playing video games
  • The screen shows a brighter area on the left edge

Display performance on the Vivo

The Vivo X100 Pro display showed significant improvements in all six attributes compared to the previous Vivo flagship, the X90 Pro+, particularly in the HDR10 video experience.

The device’s high brightness mode increased readability in sunlight. However, increasing the brightness aimed at darker shades made the image content look unnatural. The screen achieved a measured luminance of 1037 nits in an outdoor environment of 20,000 lux, but when taken into the extreme environment of 100,000 lux (direct sunlight), the device’s luminance measured a maximum of 1890 nits. This compares to the 1500 nits achieved on the X90 Pro+.

The Vivo

Like its predecessor, the Vivo X100 Pro’s weakest attribute in the protocol was motion due to dropped frames, which could affect the gaming experience.

Test summary

About SBMARK display tests: For scoring and analysis in our smartphones and other display reviews, SBMARK engineers perform a series of objective and perceptual tests under controlled laboratory and real-life conditions. Please note that we evaluate display attributes using only the device’s built-in display hardware and its still image (gallery) and video apps with default settings. (For in-depth information on how we evaluate smartphones and other displays, see our articles “How SBMARK Tests Display Quality” and “A Closer Look at SBMARK Display Tests.”

The following section brings together key elements of our comprehensive testing and analysis performed in SBMARK laboratories. Detailed performance evaluations in the form of reports are available upon request. Do not hesitate to contact us.

How the display readability score is composed

Readability evaluates the ease and comfort with which users can read fixed content (photos and web) on the display in various real-life conditions. SBMARK uses its display stand to recreate ambient light conditions ranging from total darkness to bright sunlight. In addition to laboratory tests, perceptual analysis is also carried out in real-life environments.

Measurement of luminance uniformity

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

How the display color score is composed

The color attribute evaluates the device’s ability to accurately reproduce colors. The measurements taken concern fidelity, white point color and gamut coverage. We perform color evaluations for different lighting conditions to see how well the device can handle color in its surroundings. Colors are measured using a spectrophotometer in a controlled lighting environment. The perceptual analysis of the color rendering takes place compared to the reference model displayed on a calibrated professional monitor.

Color fidelity measurements

Each arrow represents the color difference between a target color model (arrow base) and its actual measurement (arrow tip). The longer the arrow, the more visible the color difference. If the arrow remains inside the circle the color difference will only be visible to expert eyes.

Color behavior on the corner

This graph shows the color shift when the screen is tilted. Each point represents a measurement at a particular angle. The dots inside the inner circle show no color change in the corner; those between the inner and outer circles have changes that only trained experts will see; but those that fall outside the outer circle are noted.

How the Display Video score is composed

Our video attribute evaluates each device’s Standard Dynamic Range (SDR) and High Dynamic Range (HDR10) video handling in indoor and low-light conditions. We measure the tone mapping, color gamut, brightness and contrast of the display. We perform perceptual analysis Cons our professional reference monitor (Sony BVM-HX310) to ensure rendering meets artistic intent.

Gamut coverage for video content

Primary colors are measured in both HDR10 and SDR. The extracted color gamut shows the extent of the color area that the device can reproduce. To meet artistic intent, the measured gamma must match the primary color space of each video.

How the Display Motion Score is composed

The motion attribute evaluates dynamic content handling. Dropped frames, motion blur, and playback artifacts are examined using games and videos.

Dropped video frames

These long exposure photos have the number of frame irregularities in a 30 second video. Good performance shows a regular pattern (a flat gray image or a drop-down pattern).

How the Display Touch score is composed

To evaluate touch, SBMARK uses a touch robot and a high-speed camera to play and record a series of scenarios for evaluating smoothness, accuracy and response time.

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

How the display artifact score is composed

Evaluating artifacts means checking for performance, image rendering, and motion defects that can impact the end-user experience. SBMARK precisely measures device reflectance and the presence of flicker, and evaluates the impact of residual aliasing when playing video games, among other features.

The reflectance of a simple glass plate is around 4%, while it reaches around 6% for a plastic plate. Although the first surface of smartphones is glass, their total reflectance (uncoated) is usually around 5% due to the multiple reflections created by the complex optical stack.
