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.”)

Best

Pros

  • Smooth and accurate touch while gaming and when browsing the web
  • Great management of video frame drops and judder
  • Instant video playback after moving in the timeline

Cons

  • Poor color fidelity, with a strong pink cast on most still content and on HDR10 content
  • Lack of brightness indoors and outdoors, especially under sunlight
  • Visible steps during light transitions
  • Frequent frame drops when gaming

The ZTE Axon 30 Ultra 5G’s strongest points are its control of artifacts and its smoothness when gaming and browsing the web, but its overall display performance is hampered by poor color reproduction characterized by a very strong pink cast.

The ZTE device is well adapted to low-light conditions, but it otherwise lacks brightness both indoors and outdoors, and shows distinct steps when adapting to lower light levels.

Further, the Axon 30 Ultra does not use a sunlight adaptation algorithm, which means that content under sunlight is barely readable.

A strong pink cast is visible on most contents in all tested conditions, especially on skin tones.

The left-hand chart below shows the ZTE Axon 30 Ultra 5G’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 Axon 30 Ultra 5G shows a shift toward green on angle.

While the ZTE Axon 30 Ultra 5G’s video brightness is well suited for watching HDR10 content, mid-tone contrast lacks details and dark tones are hardly visible. The same strong pink cast is visible on HDR10 videos, including on skin tones, adversely affecting the overall experience.

The ZTE Axon 30 Ultra 5G shows no frame drops at 30 fps and just a few at 60 fps; however, it shows a lot of stutters when playing video games and motion blur is noticeable. A big plus is that video play resumes instantly after moving the slider forwards or backwards in the timeline. Another plus is that the device is quite smooth when browsing, when in the gallery app, and when gaming.

The ZTE device manages judder well, has smooth and accurate touch, and responds only rarely to ghost touches, but its measured touch-to-display response time at 103 ms, frequent stutters and visible aliasing make for an uncomfortable gaming experience overall.
