Fairphone 4 Display test: Decent video viewing

OTHER AVAILABLE TESTS FOR THIS DEVICE

The Fairphone 4 arrived on the market in October 2021, and as ever, the manufacturer’s aim is to produce an environmentally friendlier, user-reparable device that provides the kinds of high-end features that consumers expect. Let’s take a look at how well it performed in our Display protocol tests.

Key display specifications:

  • 6.3-inch IPS LCD display
  • Resolution: 1080 x 2340 (410 ppi)
  • Aspect ratio: 19.5:9
  • Maximum refresh rate: 60 Hz
  • Qualcomm Snapdragon 750 5G (8 nm)

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. This article highlights the most important results of our testing. 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.”)

Pros

  • Brightness well suited for indoor conditions
  • Pleasant HDR10 video rendering
  • No visible flicker

Cons

  • Too bright in low-light conditions and unreadable under sunlight
  • Strong loss of brightness and contrast when viewed on angle
  • A noticeable orange cast in all tested conditions

The Fairphone 4 has good brightness in indoor conditions, but otherwise has below-average readability and color reproduction. Lacking smoothness, it is not well suited for gaming, but it is good for watching HDR10 videos.

While the Fairphone 4 is too bright in low-light environments, including when the blue light filter (BLF) is on, the device has good readability indoors and can be read outdoors in shade.

When viewed under sunlight, content on the Fairphone 4 is difficult to read.

Whether indoors and outdoors, colors on the Fairphone 4 display have an orange cast that becomes more pronounced on angle.

The left-hand chart below shows the Fairphone 4’s color fidelity in the P3 color space. The center of each circle is the target color; the further the tip of the arrow is outside of the circle, the more users will notice the difference between the color on the display and the original color of the source material. In the scatter chart on the right, each dot represents a measurement taken at a discrete angle and distance from the device showing a full white pattern. The Fairphone 4 shifts into orange on angle.

The Fairphone 4 is good for watching HDR10 videos, with very good brightness in low light and well-rendered dark details. A pink to orange cast is visible on content, including on skin tones, but the rendering is acceptable.

The Fairphone 4 shows a few frame drops at 30 fps and when playing FHD 60 fps videos, but no frame drops are visible when playing video games. The device does not manage motion blur well, and sometimes the device pauses before resuming video playback after moving in the timeline.

The Fairphone 4 is quite accurate when zooming in the gallery app, but the device lacks smoothness regardless of the use case.

Given its screen’s LCD technology, the Fairphone device has no problems with flicker:

Although it handles judder very well, the Fairphone 4 is not suitable for a comfortable gaming experience, with touch lacking precision in corners and the device being too responsive to ghost touches. Furthermore, aliasing is noticeable.
