Pros
- Accurate colors
- Video brightness that is well suited for HDR10 content
- Smooth interactions in every use case
Cons
- Hardly readable in outdoor conditions
- In low-light conditions, too much brightness during the day and too low during the night
- Green cast when viewing HDR10 videos
- Lack of touch accuracy when playing video games, with low response from corners and edges
In our testing, the Vivo IQOO 9 Pro display’s ideal use was in indoor conditions where it provided good color rendering. But once outdoors and in low light conditions, the screen experience changed, with readability becoming difficult and uncomfortable, a considerable drawback for a mobile device.
Positioned as a gaming phone, however, a high refresh rate provided a smooth gaming and web browsing experience. The device’s smoothness also was evident when watching videos because of the very few frame drops.
With a name that stands for “I Quest On and On,” the IQOO 9 Pro, which sits at the upper end of our Premium segment, did make point gains in its display performance over a previous model we tested from this series, the IQOO 7 Legend, a High-end device, which remains in the middle of that category.
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.
Readability

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.

Color

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.
Video

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.
Motion

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.

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 Vivo iQOO 9 Pro
106 ms
Fast
Good
Bad
Slow
This response time test evaluates precisely the time elapsed between the robot touching the screen and the displayed action. This test is applied to activities that require a high reactivity, such as gaming.
Artifacts

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) Vivo iQOO 9 Pro
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.
