We subjected the Oppo Find X5 to our rigorous SBMARK Display test suite to measure its performance. Here’s how it went.
Overview
Main display specifications:
-
- 6.55 inch OLED
- Dimensions: 160.3 × 72.6 × 8.7mm
- Resolution: 2400 x 1080 pixels, 402ppi
- Aspect Ratio: 20: 9
- Refresh rate: 120Hz
Pros
- Readable in the most tested conditions with an adaptation of the brightness according to the time of day
- Fluency of the device when playing video games and in the gallery app
- Good uniformity of color and brightness
Cons
- Very saturated colors in HDR10 videos, with barely noticeable dark tones
- Strong color change when viewed from an angle
- Visible aliasing
The display of the Oppo Find X5 is suitable for general use indoors and in low light conditions, thanks to good color fidelity and good readability. But when it comes to watching videos, the oversaturated colors and hard-to-see dark tones make viewing HDR10 content rather difficult and uncomfortable on the eyes. On the other hand, for gaming, the device’s display offered a comfortable and smooth experience, with no visible frame drops, despite some aliasing.
Test summary
Learn about SBMARK visualization tests: For scoring and analysis in our smartphone and other display reviews, SBMARK engineers perform a series of objective and perceptual tests in controlled laboratory and under real-life conditions. Please note that we evaluate display attributes using only the device’s built-in display hardware and related still image (gallery) and video apps with default settings. (For in-depth information on how we rate smartphones and other displays, see our articles, “How SBMARK Tests Display Quality” and “A Closer Look at SBMARK Display Tests”.
The following section collects the key elements of our exhaustive tests and analyzes performed in SBMARK laboratories. Detailed performance evaluations in the form of reports are available upon request. Do not hesitate to contact us.
How the screen readability score is composed
Readability evaluates the ease and comfort with which users can read the display in different real-life conditions on static content (photos and web). SBMARK 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 carried out in real-life environments.

How the Display Color score is composed
The color attribute evaluates the device’s ability to accurately reproduce colors. The measurements made are for fidelity, white point color and gamma coverage. We perform color assessments 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 is compared to the reference model displayed on a calibrated professional monitor.
White point color temperature in indoor lighting conditions (1000 lux)
In the graphs below, each arrow represents the color difference between a target color model (arrow base) and its actual measurement (arrowhead). The longer the arrow, the greater the visible color difference. If the arrow stays inside the circle, the color difference will only be visible to trained eyes. In the case of the Oppo Find X5, the color spaces could have been handled better.
This graph shows the shift of color when the screen is tilted. Each point represents a measurement with a particular angle. The points inside the inner circle show no color change in the corner; those between the inner and outer circle have shifts that only trained experts will see; but those who fall outside the outer circle are noted.

How the Display Video score is composed
Our video attribute evaluates the Standard Dynamic Range (SDR) and High Dynamic Range (HDR10) video handling of each device indoors and in 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 that the rendering respects the artistic intent.
Primary colors are measured in both 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 mastering color space of each video.

How the score of Display Motion is composed
The motion attribute evaluates the handling of dynamic content. Frame drops, motion blur, and playback artifacts are investigated using games and videos.
The frame of the Oppo Find X5 drops to 30 fps

This long exposure photo presents the number of frame irregularities in a 30 second video. A good performance shows a regular pattern (a flat gray image or a drop pattern).
How the Display Touch score is composed
To evaluate touch, SBMARK uses a touch robot and a high-speed camera to reproduce and record a series of scenarios for the evaluation of fluidity, accuracy and response time.
This response time test accurately evaluates the time elapsed between the robot touching the screen and the displayed action. This test is applied to activities that require high responsiveness, such as play.
How the Display Artifacts score is composed
Evaluating artifacts means checking performance, image rendering, and motion defects that can affect the end-user experience. SBMARK accurately measures device reflectance and the presence of flickering, as well as evaluating residual aliasing when playing video games, among others.
The previous measurements show the reflection of the device within the visible spectrum range (400nm to 700nm). It includes both diffuse and specular reflection
