AudioWe put the Vivo IQOO 9 Pro through our rigorous DXOMARK Display test suite to measure its performance across six criteria. In this test results, we will break down how it fared in various tests and several common use cases.
Overview
Key display specifications:
- 6.78 inches AMOLED
- Dimensions: 164.81 x 75.2 x 8.83 mm
- Resolution: 3200 x 1440 pixels, (~518 ppi density)
- Aspect ratio: 20:9
- Refresh rate: 120 Hz

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
Vivo iQOO 9 Pro
76
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
Vivo iQOO 9 Pro
91
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.
Video
Vivo iQOO 9 Pro
91
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.
Motion
Vivo iQOO 9 Pro
87
The motion attribute evaluates the handling of dynamic contents. Frame drops, motion blur, and playback artifacts are scrutinized using games and videos.
Touch
Vivo iQOO 9 Pro
85
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.
Vivo iQOO 9 Pro 86Artifacts
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.
