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.”)

An overall score of 99 catapults the Apple iPhone 13 Pro Max into first place in our Display protocol database as of this writing. Its smoothness and accuracy when browsing, excellent color fidelity, and outstanding HDR10 rendering all add up to a very enjoyable multimedia experience in all conditions.
Although the iPhone 13 Pro Max’s brightness is not the highest among devices on the market — measured at 1066 nits vs. the Samsung Galaxy S21 Ultra (Snapdragon) measured at 1379 nits, for example — the 13 Pro Max maintains the right level of brightness for most conditions, adjusts to transitions very smoothly, provides consistent contrast, and delivers the most faithful details among all devices in our entire database, proving itself worthy of the top score for readability.
Apple’s True Tone feature is on by default. It uses sensors to measure the ambient light color and brightness, and then automatically adjusts the display to correctly show white tones under any lighting conditions. As a result, the latest Pro Max adapts its white point to the illuminant with very smooth transitions, and its rendering does not have the yellow appearance of the iPhone 12 Pro Max and earlier models. While the Samsung device’s white point is acceptable, it does not adapt its white point to the illuminant; moreover, the 13 Pro Max manages artifacts better than its rival, with well-managed flicker and almost no aliasing.
Analyses and comparisons
The DXOMARK Display overall score of 99 for the Apple iPhone 13 Pro Max is derived from its scores across six categories: readability, color, video, motion, touch, and artifacts. In this section, we’ll take a closer look at these display quality sub-scores and explain what they mean for the user, and we will compare the Apple iPhone 13 Pro Max’s performance in several areas against its predecessor, the Apple iPhone 12 Pro Max, and against two key competitors, the Samsung Galaxy S21 Ultra 5G (Snapdragon), and the OnePlus 9 Pro.

DXOMARK uses the device’s gallery app to show static (still image) content when measuring the device’s display for brightness, contrast, gamma, and blue light impact, etc.
The Apple iPhone 13 Pro Max achieves a new top score for readability, with better brightness than its predecessor and better rendering than the OnePlus and Samsung devices.
This bar graph compares the devices’ brightness and contrast levels in daylight conditions, measured using a picture in sRGB of a white rectangle on a black background.
Interestingly, the iPhone devices have the capacity to display photos taken with iPhone (HEIC files) as HDR content. With an increased peak brightness (1180 nits measured for the 13 Pro Max vs. 1100 nits for the 12 Pro Max), the 13 Pro Max can render the very bright tones in photos even better. This extended dynamic range produces a flattering effect most of the time, although we have noticed an unnatural look in certain cases. None of the tested competitors delivers this HDR rendering feature.
Overall readability is outstanding both indoors and outdoors. In indoor conditions (as in the illustration below), the Samsung Galaxy S21 Ultra 5G (Snapdragon) is brighter but shows fewer details in the hair than the iPhone 13 Pro Max, which provides the most faithful image rendering.
The Apple iPhone 13 Pro Max is very readable under sunlight, all while maintaining a natural-looking color rendering. The 13 Pro Max shows great improvement over the 12 Pro Max in brightness, but also when it comes to visibility of details in dark areas. Note that in the illustration below, the Samsung image appears brighter than the 13 Pro Max image (1379 nits measured on the Samsung and 1066 nits measured on the iPhone), but our engineers found that after a few minutes in sunlight, the S21 Ultra 5G (Snapdragon) would tamp down its brightness, presumably to keep from overheating. The 13 Pro Max did not have any issues in similar conditions and maintained its brightness.
The Apple iPhone 13 Pro Max adapts its brightness very smoothly to changing lighting conditions. At its default settings, however, the device is still too dark when reading at night (blue light filter off):

DXOMARK uses the device’s gallery app to show static (still image) content when measuring the device’s display for white point, gamut, uniformity, color fidelity, and blue light filter impact, etc.
The iPhone 13 Pro Max adapts its white point to lighting conditions. It has good color fidelity, and it is much less yellow than the iPhone 12 Pro Max overall. In the example below, the Samsung image is clearly oversaturated.
Although the iPhone 13 Pro Max has a slight green cast outdoors, it is still more accurate and pleasant than the Samsung Galaxy S21 Ultra 5G (Snapdragon), which is too saturated and orange.
The Apple iPhone 13 Pro Max shows no major color changes when held on angle, which is again a great improvement over its predecessor. On angle, the iPhone 13 Pro Max keeps its colors, while the iPhone 12 Pro Max turns green, and the Samsung Galaxy S21 Ultra 5G (Snapdragon) turns very blue.

In the charts below, each dot represents a measurement taken at a discrete angle and distance from the device showing a full white pattern; dots inside the inner circle exhibit no color shift; those between the inner and outer circle have shifts that are just noticeable by trained experts; but those falling outside the outer circle are noticeable. As the color scatters show, the iPhone 13 Pro Max’s dots remain closer to the circles, which means it shifts far less on angle than either the iPhone 12 Pro Max or the Samsung Galaxy S21 Ultra 5G (Snapdragon):
But while its overall color rendering is much improved over the 12 Pro Max, the iPhone 13 Pro Max still has the same very noticeable orange cast with the blue light filter on as the 12 Pro Max.

DXOMARK uses the device’s video (or browser) app to show dynamic content when measuring the device’s display for brightness, contrast, gamma, and color.
The Apple iPhone 13 Pro Max is very good for watching HDR10 videos. There are no frame drops nor judder, and its HDR rendering is outstanding. Further, it has a wider dynamic range and good brightness, and does a better job with contrast and tone mapping than the 12 Pro Max.
In low-light conditions, the iPhone 13 Pro Max is significantly dimmer than the Samsung Galaxy S21 Ultra 5G (Snapdragon) when playing SDR content, and Apple users may want to manually increase brightness:
The iPhone 13 Pro Max’s video colors are faithful, especially compared to the 12 Pro Max, which has a visibly yellow cast. When judged against the test reference photo, the colors on both the 13 Pro Max and the Samsung land just on either side, with the 13 Pro Max on the warmer side and the Samsung appearing somewhat cooler.

The Apple iPhone 13 Pro Max shows no frame drops nor stutters when playing videos, unlike the 12 Pro Max, the S21 Ultra 5G (Snapdragon), and the OnePlus 9 Pro. Further, the iPhone 13 Pro Max has no judder at 24, 30, and 60 fps videos, which is also true of the Samsung device. In order to show a 24 fps video on a 60 Hz display, such as on the iPhone 12 Pro Max, the device needs to perform a 3:2 pulldown as illustrated in the photo below.
Moving objects appear sharp in videos. The device is reactive when jumping backwards or forwards in videos; however, in some cases there can be some blocking or some pixelating artifacts, but this behavior is quite rare.
When gaming, our testers experienced no frame drops with the iPhone 13 Pro Max, although some were visible on the 12 Pro Max and the S21 Ultra 5G (Snapdragon).

Touch on the iPhone 13 Pro Max is accurate and very smooth in the gallery app, when browsing the web, and in general use (switching apps, navigating within the phone, etc.). It is indeed smoother than the iPhone 12 Pro Max in those cases, thus showing the benefits of its adaptive 120 Hz refresh rate, but the 13 Pro Max shows no improvement when it comes to smoothness when gaming.

The Apple iPhone 13 Pro Max shows excellent control of artifacts. It does not respond to ghost touches, and it manages flicker well. In fact, both the Samsung device and the iPhone 12 Pro Max have noticeable flicker at intervals of 240 Hz in the video below. The iPhone 13 Pro Max and the iPhone 13 flicker at twice the speed of the other devices (that is, at 480 Hz), which makes flicker on these most recent Apple devices less noticeable.
Looking at the iPhone 13 Pro Max’s bright stripes, however, one is bright (and quite white) and the next one is less bright (and pinkish as well), creating an alternating pattern of bright stripes and darker stripes. The net visual effect for some users may result in a prolongation of the dark zone, making flicker a bit more visible on the iPhone 13 Pro Max than on the iPhone 13.
Even though the iPhone 13 Pro Max’s notch is smaller than the one on the 12 Pro Max, the screen-to-body ratio remains smaller than that of its competitors.
The Apple iPhone 13 Pro Max shows improvement over the iPhone 12 Pro Max and does a decidedly better job of handling aliasing than the Samsung Galaxy S21 Ultra 5G (Snapdragon), as illustrated below.
Our Apple iPhone13 Pro Max test results clearly demonstrate major improvements over the iPhone 12 Pro Max in several key areas of display performance. But above all, the screen’s exceptionally smooth adaptation to changing lighting conditions in all use cases means that users will have a consistently pleasant viewing experience in terms of brightness, contrast, and color. The iPhone 13 Pro Max might not have the highest level of brightness when compared with its competitors, but the device more than makes up for this with its fine-tuned and excellent rendering of content.
