Pros
- Good color rendering in every lighting condition
- Well-managed brightness levels in every use case
- Smooth display in all use cases
Cons
- Lack of brightness when watching HDR10 videos
- Lack of contrast when watching HDR10 videos
The Oppo Find X7 Ultra’s display overall score was supported by the device’s strong results in the color and touch attributes, which helped to counter a middling video score. The device showed good color rendering in every use case tested, and the device’s screen smoothness was evident in all the use cases.
Oppo’s latest flagship made a slight improvement over previous Oppo models, despite the screen’s slightly low brightness. However, screen brightness in sunlight was close in performance to other ultra-premium devices.
The lack of brightness affected the video-watching experience, making it uncomfortable to watch HDR10 content because dark tones were hard to see. As a result, it will be necessary for most users to adjust the device luminance manually.
The OPPO Find X7 Ultra is the first device to receive the DXOMARK Eye Comfort Label after having passed all four key criteria: temporal light modulation, brightness level, blue light filtering, and color consistency.
Our measurements showed that the device was essentially free of flicker, with a 10% chance of the user perceiving any brightness abnormalities. Manual adjustment of the display luminance can go as low as 1.5 nits, which is low enough even for the most sensitive eyes under dark room conditions. Our testers particularly appreciated the blue-light filtering performance in the device’s “Bedtime Mode,” which efficiently, and continuously, adapted the blue-light filtering to the time of day. The device’s circadian action factor, which indicates the level of disturbance induced by artificial lighting on human sleep cycle, reached an impressive 0.63, below DXOMARK’s already challenging recommended maximum threshold of 0.65. And when it came to color accuracy, the device was able to maintain almost all of its P3 color gamut with the blue-light filter mode activated.
Test summary
About DXOMARK Display tests: For scoring and analysis, a device undergoes a series of objective and perceptual tests in controlled lab and real-life conditions. The DXOMARK Display score takes into account the overall user experience the screen provides, considering the hardware capacity and the software tuning. In testing, only factory-installed video and photo apps are used. More in-depth details about how DXOMARK tests displays are available in the article “A closer look at DXOMARK Display testing.”
The following section focuses on the key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Full reports with detailed performance evaluations are available upon request. To order a copy, please contact us.

How Display Readability score is composed
Readability evaluates the user’s ease and comfort of viewing still content, such as photos or a web page, on the display under different lighting conditions. Our measurements run in the labs are completed by perceptual testing and analysis.
Luminance under various lighting conditions
This graph shows the screen luminance in environments that range from total darkness to outdoor conditions. In our labs, the indoor environment (250 lux to 830 lux) simulates the artificial and natural lighting conditions commonly seen in homes (with medium diffusion); the outdoor environment (from 20,000 lux) replicates a situation with highly diffused light.
Contrast under various lighting conditions
This graph shows the screen’s contrast levels in lighting environments that range from total darkness to outdoor conditions. In our labs, the indoor environment (250 lux to 830 lux) simulates the artificial and natural lighting conditions commonly seen in homes (with medium diffusion); the outdoor environment (from 20,000 lux) replicates a situation with highly diffused light.
Photo EOTF
The Electro-Optical Transfer Function (EOTF) defines how bits are converted into luminance out of the display. Gray levels (horizontal axis) represent the different shades from pure white (100% gray level) to pitch black (0% gray level). The standard for still images follows a 2.2 gamma. The flatter the curves, the harder it is to perceive differences between consecutive shades. This phenomenon is more frequent under intensive lighting conditions (20,000 lux) in the low gray level regions.

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.
Average reflectance is computed based on the spectral reflectance in the visible spectrum range (see graph below) and human spectral sensitivity.
Average reflectance is computed based on the spectral reflectance in the visible spectrum range (see graph below) and human spectral sensitivity.
Reflectance (SCI)
Wavelength (horizontal axis) defines light color, but also our capacity to see it; for example, UV is a very low wavelength that the human eye cannot see; Infrared is a high wavelength that the human eye also cannot see). White light is composed of all wavelengths between 400 nm and 700 nm, i.e. the range the human eye can see. Measurements above show the reflection of the devices within the visible spectrum range (400 nm to 700 nm).
Uniformity
This graph shows the distribution of luminance throughout the entire display panel. Uniformity is measured with a 20% gray pattern, with bright green indicating ideal luminance. An evenly spread-out bright green color on the screen indicates that the display’s brightness is uniform. Other colors indicate a loss of uniformity.

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 most important modulation. The combination of a low frequency and a high peak is susceptible to inducing eye fatigue.

How Display Color score is composed
Color evaluations are performed in different lighting conditions to see how well the device manages color with the surrounding environment. Devices are tested with sRGB and Display-P3 image patterns. Both faithful mode and default mode are used for our evaluation. Our measurements run in the labs are completed by perceptual testing & analysis.
White point color under D65 illuminant at 830 lux
This graph shows the white point coordinates for the image pattern using the default or the faithful mode. D65 illuminant (6500 Kelvin) is a standard that defines the color of white at midday; it is used for display calibration as a white reference, therefore devices are expected to be at or close to the D65 white point.
Color fidelity
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. The tested color mode is the most faithful proposed by each device, and a color correction is applied to account for the different white points of each device.
White color shift with 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.

The circadian action factor is a metric that defines how light impacts the human sleep cycle. It is the ratio of the light energy contributing to sleep disturbances (centered around 450 nm, representing blue light) over the light energy contributing to our perception (covering 400 nm to 700 nm and centered on 550 nm, which is green light). A high circadian action factor means that the ambient light contains strong blue-light energy and is likely to affect the body’s sleep cycle, while a low circadian action factor implies the light has weak blue-light energy and is less likely to affect sleeping patterns.
Spectrum of white emission with Night mode ON
Spectrum measurements of a white web page with BLF mode on and off. This graph shows the impact of blue light filtering on the whole spectrum. All other settings used are default, in particular, the luminance level follows the auto-brightness adaptation from the manufacturer.
The wavelength (horizontal axis) defines light color but also the capacity to see it. For example, UV, which has a very low wavelength, and infra-red, which has a high wavelength, are both not visible to the human eye. White light is composed of all wavelengths between 400 nm and 700 nm, which is the range visible to the human eye.

SDR video EOTF curve
These curves represent the SDR video tone distribution for white color.
The Electro-Optical Transfer Function (EOTF) defines how bits are converted into luminance out of the display. Gray levels (horizontal axis) represent the different shades from pure white (100% gray level) to pitch black (0% gray level). The standard for SDR videos follows a 2.2 gamma. The flatter the curves, the harder it is to perceive differences between consecutive shades. This phenomenon is more frequent under bright lighting conditions (830 lux) in the low gray levels region (< 30%).

HDR10 video EOTF curve
These curves represent the HDR10 video tone distribution for white color.
The Electro-Optical Transfer Function (EOTF) defines how bits are converted into luminance out of the display. Gray levels (horizontal axis) represent the different shades from pure white (100% gray level) to pitch black (0% gray level). While the PQ (Perceptual Quantizer) standard is reminded here for reference, it cannot be a target for smartphones as it is an absolute standard whereas smartphones adapt their brightness to lighting conditions. The flatter the curves, the harder it is to perceive differences between consecutive shades. This phenomenon is more frequent under bright lighting conditions (830 lux) in the low gray levels region (< 30%).
