This device has been retested in the latest version of our protocol. This summary has been fully updated. For detailed information, check the What’s New article
OTHER AVAILABLE TESTS FOR THIS DEVICE

We put the Poco F4 GT 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 a variety of tests and several common use cases.

Overview

Key display specifications:

  • 6.67 inches AMOLED, 107.4 cm2 (~87.3% screen-to-body ratio)
  • Dimensions: 162.5 x 76.7 x 8.5 mm (6.40 x 3.02 x 0.33 inches)
  • Resolution: 1080 x 2400 pixels, (~395 ppi density)
  • Aspect ratio: 20:9
  • Refresh rate: 120 Hz

Pros

  • Smooth screen interactions in all tested use cases
  • Touch accuracy when playing  video games
  • Very smooth adaptability during lighting transitions

Cons

  • Unreadable under sunlight
  • Lacking in color and brightness when viewing videos
  • Many frame drops in video playback at  30 fps and 60 fps

The Poco F4 GT display’s performance was smooth in all tested use cases. But it really stood out when playing video games, not only because of its smoothness, but also because of its accuracy and fast reaction time during gaming. Despite very smooth adaptation to lighting transitions, the Poco F4 GT’s display was unreadable under sunlight. The device was also not ideal for watching videos because of color issues (visible green cast), and brightness levels that were too low.

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.

Luminance uniformity measurement

This graph shows the uniformity of the display with a 20% gray pattern. The more visible the green color, the more uniform the display.

Color

Huawei Mate 50 Pro
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.

Color fidelity measurements

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.

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.

SDR Gamut coverage
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.

Video frame drops

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).

Touch

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 POCO F4 GT

Slow
This response time test evaluates precisely the time elapsed between a single touch of the robot on 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.
