We subjected the Asus ROG Phone 7 to our rigorous SBMARK Display test suite to measure its performance Cons six criteria. In the results of this test, we’ll analyze how it performed in a number of tests and several common use cases.
Overview
Main specifications of the display:
- 6.78-inch AMOLED (~84.2% screen-to-body ratio)
- Dimensions: 173.0 x 77.0 x 10.3 mm (6.81 x 3.03 x 0.41 inch)
- Resolution: 1080 x 2440 pixels, (~395 ppi density)
- Aspect Ratio: 20.4:9
- Refresh Rate: 165Hz
Pros
- Suitable brightness in most lighting conditions
- Correct color rendering in all lighting conditions
- Screenshot accurate in all tested use cases
Against
- It lacks legibility in sunlight despite its proper luminance
- The light transitions on the screen are too fast in both increasing and decreasing light conditions
- The screen shows stuttering and aliasing during games.
The display performance of the Asus ROG Phone 7 was very good overall, largely due to its touch capabilities, which are important for a device marketed for gaming.
In this regard, the touch response of the ROG Phone 7 screen has always been precise. Also, the smartphone handled browsing the web or playing games smoothly and comfortably.
However, the screen had a tendency to exhibit visible aliasing and stuttering when playing video games which detracted from the overall gaming experience. In another use case, i.e. watching videos, the device was unable to smoothly play videos at 60 frames per second with no mismatched frames.
Otherwise, when the device was used in indoor lighting conditions, the brightness of the screen was always well managed and did not require any manual adjustments to play games, scroll or simply view photos.
Trial summary
Learn about SBMARK display tests: For scoring and analysis in our smartphone and other display reviews, SBMARK engineers perform a series of objective and perceptual tests under real-life and controlled laboratory 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, check out our articles “How SBMARK Tests Display Quality” and “A Closer Look at SBMARK Display Tests.”
The following section compiles the key elements of our extensive testing and analysis performed in the 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 the still content (photos and web) on the display under 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 performed in real-life environments.

Measurement of luminance uniformity

How the display color score is composed
The color attribute evaluates the device’s ability to reproduce colors accurately. Measurements taken include fidelity, white point color, and gamut 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 takes place with respect to the reference model displayed on a calibrated professional monitor.

Each arrow represents the color difference between a target color pattern (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 within the inner circle show no color change in the corner; those between the inner and outer circle have changes that only trained experts will be able to 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 respects artistic intent.

Gamut coverage for video content
Primary colors are measured in both HDR10 and SDR. The extracted color gamut shows the extent of color area that the device can reproduce. To meet artistic intent, the measured gamut should match the primary color space of each video.
How the Display Motion score is composed
The motion attribute evaluates the handling of dynamic content. Dropped frames, motion blur, and playback artifacts are examined using games and videos.
Video frame drops
These long exposure photos feature the number of frame irregularities in a 30 second video. A good performance shows a regular pattern (a flat gray image or drop-down pattern).
How the Display Touch score is composed
To evaluate touch, SBMARK uses a haptic robot and a high-speed camera to play and record a series of scenarios for evaluating fluency, accuracy and response time.
This response time test accurately evaluates the time between a single tap of the robot on the screen and the displayed action. This test is applied to activities that require high responsiveness, such as playing games.
How the display artifact score is composed
Evaluating artifacts means checking performance, image rendering, and motion artifacts that can affect the end-user experience. SBMARK accurately measures device reflectance and flicker, and assesses the impact of residual aliasing when playing games, among other characteristics.
