Google Pixel 4 & 4 XL Display Analysis — Outshined by serious phonemakers

It’s nearing the top of 2019, and most smartphone makers have already showcased their flagship telephone for this yr. Google’s flagship is available in fairly late into the yr, however within the tech world, a number of months can imply an entire new era of {hardware} capabilities.

Nonetheless, the Pixels usually are not notably recognized for his or her cutting-edge {hardware} — as an alternative, they prefer to make use of software program to distinguish themselves, by means of helpful optimizations and nifty options. For shows, the software program aspect is usually restricted to calibration and subjective lodging, so that is the place we count on Google to shine in.

Pixel Four Show Evaluate Highlights

  • Shameful peak brightness that’s dimmer than most different telephones
  • Improved black clipping in comparison with earlier Pixel fashions, with notable significance within the Pixel 4
  • Finest whole colour accuracy measured in a smartphone
  • Distinction/gamma inconsistencies within the Pixel Four XL
  • Increased grayscale colour unfold within the Pixel 4
  • Novel, fluid 90Hz cell show
  • Finest viewing angles on the Pixel 4

Final yr, Google sourced their Pixel Three show from LG whereas sourcing the Pixel Three XL show from Samsung. Google continues the identical panel sourcing this yr, placing an LG show on the Pixel Four whereas the Pixel Four XL is provided with a Samsung show. Sadly, neither telephones are utilizing current-generation OLED panels — the Samsung show on the Pixel Four XL is similar one discovered on the OnePlus 7 Professional, which is a last-gen Samsung panel, and the Pixel Four is utilizing the identical panel discovered on the Huawei Mate 30 Professional, which pales compared to Samsung’s newest show panels. Samsung’s current-generation show panels promote a brand new blue emitter materials and an enchancment in energy effectivity and show brightness. Neither Pixel Four system sees these advantages.

The 2 sizes even have totally different show pixel densities: the Pixel Four has a pixel density of 444 pixels per inch (FHD+), whereas the bigger Pixel Four XL is sharper at 537 pixels per inch (QHD+). To my eyes, this distinction is noticeable when viewing textual content. Whereas the Google Pixel Four does seem structurally sharp, I can generally make out pink and inexperienced colours fringed subsequent to textual content because of the OLED PenTile pixel association. Alternatively, the Google Pixel Four XL seems completely sharp, and I can not make out colour fringing regardless of how shut I’m to the show. Nonetheless, for most individuals, the decrease decision on the smaller Pixel Four shouldn’t be a difficulty.


Google applied a brand new dynamic show white stability system within the Pixel 4, known as AmbientEQ, which makes use of the brand new RGB ambient mild sensor to vary the white stability of the show nearer to the colour temperature of the encircling mild. The aim of the function is to make the show seem extra like a naturally-reflective floor, like a bit of paper. The rationale for that is that our notion of any given colour adjustments relying on the colour temperature of our surrounding surroundings. For instance, the colour of white in your smartphone might look considerably colder when seen below heat, dim ambient lighting of some hipster restaurant. Altering the white stability of your show nearer to that of the ambient lighting might help make your telephone show seem extra “natural” and straightforward on the eyes, in addition to assist it seem extra constant between totally different lighting situations.  The function is a parallel to Apple’s True Tone function. Nonetheless, Google’s AmbientEQ is rather more delicate than True Tone, and for my part, it’s not practically as efficient as True Tone. AmbientEQ is restricted between 6300 Ok and 7450 Ok show colour temperatures, which is rather more slender than True Tone’s vary. Google has additionally beforehand applied AmbientEQ of their House Hub show (now Nest Hub), and it really works a lot better on that than it does on the Pixel 4. Luckily, we’re in a position to change the conduct of AmbientEQ and form it to be extra conscious of ambient lighting.

LG OLED viewing angles

One underappreciated side of the LG panel within the Pixel Four is its viewing angles — LG OLEDs have the least colour shift on any cell OLED. Along with AmbientEQ and the Pixels’ flat show, the viewing angles actually assist enhance their laminated “papery” look because the show doesn’t change colours at totally different angles. Nonetheless, I do want the Pixel Four had a higher-resolution show, which might additional enhance the paper phantasm.

The viewing angles on the Pixel Four XL can tint barely blue at average angles. Nonetheless, it’s on-par with one of the best on Samsung’s newest shows, which hasn’t modified a lot previously few generations. I’m keen on realizing if the distinction in viewing angles between the 2 distributors lies throughout the cavity design of the emitters or with the polarizer stack.

Clean Show

And lastly, Google’s headling new function for the Pixel Four is its 90Hz “Smooth Display.” Increased refresh charges promote vital enhancements in UI fluidity and contact response, they usually want to change into a much bigger development subsequent yr within the cell market. Nonetheless, no cell OLED at present helps a variable refresh price, and I believe it’s a mistake to implement the next refresh price system till variable refresh price panels change into accessible. For now, excessive refresh price cell OLEDs use discrete show modes for various refresh charges and use software program to change between larger and decrease refresh price show modes to preserve battery. The totally different show modes every require their very own calibration tables, they usually’re not prone to completely match with one another. These imperfections could also be seen when the show switches from one show mode to a different, and Google’s software program engineers have acknowledged this as a limitation of this software-based dynamic refresh price system.


Show Profiles & Coloration Gamut

The Google Pixel Four has three totally different show profiles: AdaptivePure, and Boosted. All three profiles share the identical white level, the identical switch traits, they usually all help Android’s colour administration system.

The Adaptive profile is the default show profile of the Google Pixel 4. It’s a colour saturation-expanding profile that has elevated vibrancy in reds and greens in comparison with customary sRGB. Extra exactly, pink colours are measured to be about 10% extra saturated, whereas greens are about 20% extra saturated. Reds are additionally shifted barely orange, whereas greens seem only a contact yellower. Blue colours obtain no enhance in saturation, however the adjusted primaries end in barely lighter blue tones. It targets a regular 2.20 gamma and a D67 (6700 Ok) white level, like the opposite two profiles.

Up to date Adaptive profile

On earlier Pixel units, the Adaptive profile didn’t help colour administration, however with the Pixel 4, Google has up to date the Adaptive profile to help it. The brand new Adaptive profile now makes use of Show P3 as its composition colour house, as an alternative of sRGB remapped to a wider gamut. This permits the Adaptive profile to lastly be constant between totally different Pixel shows, and constant in white level with the Pure and Boosted show profiles. For earlier Pixel generations, this was not the case. In consequence, each the Google Pixel Four and Pixel Four XL now have visually-identical Adaptive profiles, and the Pure and Adaptive profiles share white factors. For color-managed content material, the Adaptive profile maintains its rendering intent and renders the color-managed content material with elevated vibrancy. Nonetheless, the Adaptive profile clips at P3 primaries, and it’ll clip high-saturation P3 content material.

The Pure profile is the correct show profile that follows {industry} requirements (though internally concentrating on a D67 white level). That is the profile to make use of to get probably the most correct colours out of the Google Pixel Four show.

The Boosted profile is much like the Pure profile, nevertheless it offers a slight enhance in whole colour saturation. Google says that we understand colours as much less vibrant on smaller screens, like telephones, which is their foundation for the inclusion of this profile.

Pixel Four Brightness

Google Pixel 4 and Pixel 4 XL display brightness

Comparative brightness chart

The Pixel units have traditionally been unimpressive in terms of show brightness. This yr isn’t any totally different. Whereas each different main smartphone maker has made their OLEDs considerably brighter, Google has proven little-to-no progress. Google did handle to extend its latest telephones’ brightness this yr, from about 400 nits as much as 450 nits, nevertheless it nonetheless leaves them as a few of the dimmest flagship smartphones in recent times.

Lack of excessive brightness mode

The rationale Google is up to now behind is that they’re refusing to include a higher-power brightness state for his or her system brightness. Moreover, Google is utilizing last-generation show panels that can’t compete in energy effectivity or in rated brightness with Samsung’s newest panels. What’s attention-grabbing is that Google has had the next brightness mode inside their telephones, which they’ll faucet into throughout HDR playback (or with root). However for causes possible associated to battery, Google doesn’t enable their telephones to make use of this further brightness for regular use. Increased brightness modes do require considerably extra energy to drive — an 800-nit peak brightness state drains considerably extra energy than twice that of a 400-nit brightness state — but when the competitors is ready to help larger brightness ranges and keep higher battery life than the Pixel units, then Google is severely falling behind in each departments.

When enabling excessive brightness mode throughout the Pixel 4s’, their shows method acceptable ranges of brightness. At 600 nits, this ranks the Google Pixel Four shows competitively with final years’ OLEDs in brightness. However in 2019, 600 nits is concerning the baseline for each main smartphone firm, whereas one of the best are pushing 800 nits (100% APL). These are merely the boundaries of Google’s outdated panels, as the identical panels discovered within the Huawei Mate 30 Professional and the OnePlus 7 Professional push the identical brightness ranges — besides these telephones really push these brightness ranges in regular use.

Digicam viewfinder potential

As an organization that focuses its telephone advertising and marketing and identification on their digicam, Google would profit its marketing campaign by having a brighter display. This might help the digicam expertise by bettering the accuracy of the viewfinder. The composition of a photograph is a key issue of a great image, which is aided primarily by what you see within the viewfinder. Google applied Stay HDR+ within the Pixel Four viewfinder in order that what you see earlier than you’re taking an image appears nearer to the image that’s captured and processed. Nonetheless, throughout daylight pictures, the viewfinder can look washed out if the show can’t get brilliant sufficient to precisely reproduce the scene. This is among the key benefits of the optical viewfinders in SLRs, which reveals the scene on the brightness and distinction that your eye would see. One different manner that telephone makers can enhance their digicam viewfinders is by utilizing an absolute HDR viewfinder within the digicam app, which might map the digicam viewfinder on the telephone show to the identical absolute brightness because the scene.

Adjusted brightness response to APL

Final yr, the DDIC within the Pixel Three XL was adjusted to restrict its brightness at decrease emission ranges (APL) to that of full-screen white (100% APL). Whereas this will seem to be a crippling transfer, it’s really a essential step for OLEDs in order that they’ll have a constant gamma calibration. The LG panel within the smaller Pixel Three had a variable brightness response to APL, and it had an inaccurate and dramatically variant gamma vary. Now with the brand new LG panel within the Pixel 4, it too has its decrease emission brightness restricted, so it ought to have vital enhancements in gamma calibration. The Samsung panel within the Pixel Four XL panel continues to retain this attribute.

Pixel Four Grayscale Accuracy

Google Pixel 4 & 4 XL Display Analysis — Outshined by serious phonemakers

Grayscale plots for Pixel 4, 60Hz

Pixel telephone shows have additionally been traditionally poor at grayscale consistency, typically taking up a tint for darker colours and at decrease show brightness. The calibration course of on the manufacturing unit can solely repair a lot, and might even make it worse. A show with a constant grayscale can sometimes be attributed to tight OLED manufacturing tolerances and a mature fabrication course of on the show manufacturing line. Google has a popularity for not offering the highest quality management of their telephones’ {hardware}, and for good causes. The principle offender has been the LG panels that Google has been utilizing of their telephones, and this yr it’s the same story. Google makes use of an LG panel for the smaller Pixel 4, and whereas it’s a clear enchancment over earlier generations, it nonetheless reveals the next unfold in its grayscale in comparison with some Samsung panels. The Google Pixel Four XL makes use of a Samsung panel and clearly reveals superior grayscale consistency in our plots above. In comparison with the iPhone 11 Professional’s impeccable grayscale plots, nevertheless, there may be nonetheless room for enchancment.

“Flickering” between refresh charges

Because the Pixel 4s’ panels do not need a real variable refresh price, Google makes use of separate show modes with totally different show timings for 60Hz and 90Hz (which is regular for any non-variable refresh price show). This ends in totally different show traits for the 2 modes, and particular person calibration tables are essential for each modes to seem comparable. Nonetheless, an ideal calibration is just about unattainable at mass manufacturing. For OLEDs, calibration missteps and sign drift/variance are very noticeable for darkish shades at low sign ranges, much like elevated digicam noise in low mild. Within the Google Pixel Four and Pixel Four XL, the variations in calibration of the 2 refresh charges are evident of their darker shades. For each telephones, the 90Hz show mode is tinted extra green-cyan than in its 60Hz show mode. The distinction is most noticeable at low brightness for darkish colours, being probably the most extreme between 10-20 nits. This variance is the rationale for Google’s difficulties with implementing their auto-switching Clean Show system. Be aware that Google is just not the one OEM with this challenge; variations in calibration are additionally current between the totally different refresh price modes in different excessive refresh price OLED panels, like OnePlus’ newest telephones, or the ROG Cellphone II.

Pixel Four Coloration Accuracy

Common sRGB colour accuracy plots for Google Pixel 4, Pure profile

Google Pixel 4 and Pixel 4 XL display color accuracy

Comparative colour accuracy chart

One space the place Google has often excelled in is colour accuracy. Their telephones have been aggressive in colour accuracy yearly, and Google manages to proceed this development in 2019. Our testbench for colour accuracy consists of 37 constant-luminance factors at 5 totally different stimulus ranges, over the show’s brightness vary. Most colours in photographs and movies are inside 15–40% depth, whereas colours in app/net design & UI generally include tones above 50% depth, so you will need to measure colours in any respect stimulus ranges. The brand new ΔETP colour distinction metric improves on these lower-stimulus readings, which we now use to evaluate the full colour accuracy of a show.

Correct white level?

Each our Google Pixel Four and Pixel Four XL items have white factors which might be remarkably correct to the D65 customary. Our Google Pixel Four common white factors measure at 6586 Ok (ΔETP = 1.3), whereas our Pixel Four XL measures extra precisely at 6477 Ok (ΔETP = 0.4). Though I want to rave about how correct these white factors are, Google is internally concentrating on a white level of D67 (6700 Ok), so I can’t say that they hit their mark. Nonetheless, I’d like to notice {that a} D67 white level for OLEDs may very well be extra correct than concentrating on D65, since trendy OLEDs are topic to metameric failure (as a consequence of slender spectral band primaries from vast colour enlargement), and seem hotter than an LCD or a CRT on the identical spectral energy distribution.1 2 Due to this, I really want extra OEMs would goal this white level for OLED shows. Additionally, most of them are inclined to ship with white factors hotter than their goal, anyway.

Improved colour lightness

Some earlier Pixel units, whereas being correct chromatically, exhibited distinction points and darker colours than customary. This was a standard challenge with all OLED panels up till the Samsung Galaxy S9, which was the primary smartphone show to regulate its brightness-APL response. Google mounted this on the Pixel Three XL, however the LG panel on the Pixel Three nonetheless had the difficulty. With the brand new LG panel on the Pixel 4, Google has additionally improved its brightness-APL response, and now each the Pixel Four and Pixel Four XL have wonderful whole colour accuracy. Each shows have a mean ΔETP decrease than 3.Zero for sRGB and Show P3, with small most errors. Nonetheless, when contemplating luminance error, we see that the smaller Google Pixel Four does appear to have extra points in colour lightness past gamma. Though the distinction on the smaller Google Pixel Four is sort of correct, some colours nonetheless seem barely darker than anticipated, notably throughout the pink colour mixtures and blues. This may very well be brought on by its white level creeping in the direction of magenta, away from inexperienced which makes up a lot of the luminance in RGB colour mixtures. It’s nonetheless a transparent enchancment over the Pixel 3, and these lightness points shouldn’t be seen by most since it’s under our reference threshold (ΔEI = -2.8)

Business-leading colour accuracy

On the Samsung show within the Pixel Four XL, Google is displaying industry-leading whole accuracy, exhibiting the bottom colour errors I’ve seen on any of the most recent smartphones in our thorough testbench. The Pixel Four XL measures a mean whole colour accuracy ΔEITP of 1.7, which is a noticeable leap forward of different 2019 flagships. For max depth colours, the Pixel Four XL reveals colour accuracy efficiency that rivals and even outperforms {many professional} reference displays, with a mean ΔETP of 0.9, which is below our visible threshold (ΔETP < 1).

Whereas the shows on the iPhone 11 Professional and the Galaxy Be aware10 are nonetheless at present best-in-class, they share two flaws: each have hotter white factors than customary, and each exhibit oversaturation at decrease intensities [iPhone 11 Pro,  Galaxy Note10]. Most show critiques don’t cowl lower-stimulus colours (DisplayMate solely checks max-brightness & max-intensity take a look at colours), and most show critiques use the older ΔE2000 colour error metric, which under-reports lower-intensity colours as a result of the metric assumes visible adaptation to a selected white stage. Thus, the older ΔE2000 metric is just not as efficient for content material with decrease image ranges (most movies; colours in darkish mode apps) or for HDR colour accuracy evaluation. The Google Pixel Four and Pixel Four XL do present slight undersaturation at decrease colour intensities, however total keep nice accuracy in any respect intensities.

Pixel Four Distinction & Tone Response

Google Pixel 4 & 4 XL Display Analysis — Outshined by serious phonemakers

Common gamma for the Google Pixel 4

Show distinction and gamma are usually considered crucial components in an correct show. Since Google sources their shows from two totally different distributors, there’s certain to be variations between them. An important variations are often discovered inside their gamma scales, and the gamma conduct between the Google Pixel Four and Pixel Four XL panels are literally fairly totally different.

Unstable Pixel Four XL gamma

The Pixel Four XL’s gamma calibration is slightly troubling. At most brightness, the Google Pixel Four XL show distinction is just about excellent — it’s a totally straight 2.20 gamma energy. Nonetheless, as show brightness reduces, the Pixel Four XL’s gamma adjustments. Round 50% brightness (~200 nits), the Pixel Four XL’s gamma scale is now not straight and sees a steep decline in darkish shades. At about 70 nits, the Pixel Four XL seemingly takes on a unique show calibration with a jagged gamma that approximates a excessive 2.43 gamma energy. Colours under 10% depth, which covers a big portion of the shadows in photographs, are so darkish that they’re just about clipped. At medium-to-low show brightness, the distinction within the Pixel Four XL is a slight regression from the Pixel Three XL, besides that Google has mounted the gross miscalibration current within the Pixel Three XL at minimal brightness. I can’t assist however assume that Google has targeted totally on making the max brightness gamma correct to realize a excessive mark from DisplayMate, whose testbench solely measures gamma at max brightness. Not solely in gamma, however in colour accuracy as properly. That is much like the Galaxy S10 and Galaxy Be aware10 (Snapdragon) the place solely max brightness has a straight 2.20 gamma energy, and it will get progressively worse at decrease show brightness.

Google Pixel 4 XL display gamma bug

Regular (left), bugged gamma (proper)

There additionally appears to be a bug unique to the Google Pixel Four XL which leads to jarring show calibration. From my testing, the Pixel Four XL applies the flawed gamma calibration when waking the show up with 90Hz enabled and At all times-On Show disabled. Each the 90Hz and the AOD modes have their very own show calibrations, and the Pixel Four XL will get confused someplace in determining what show calibration to use when waking up the show. The bug isn’t too noticeable above 50% brightness, nevertheless it does nonetheless barely have an effect on the white level and show saturation. The problem turns into more and more extreme at decrease brightness, taking pictures the show gamma by means of the roof at minimal brightness and considerably clipping colour tones.

Pixel 4: Most improved (LG) show

Alternatively, the smaller Google Pixel Four has fantastically calibrated show distinction, which will be partially accredited to its mounted brightness response to APL. It has an impressively low variance for its higher show brightness vary, ranging simply between a 2.21 and a 2.23 straight gamma energy. For decrease brightness ranges, the Google Pixel Four lifts its shadows, which leads to a decrease show gamma. That is each a blessing and a curse, because the Google Pixel Four reveals exemplary OLED near-black rendering at the price of lowered picture distinction at decrease show brightness. The Google Pixel Four is the primary Android OLED show I’ve seen to be able to rendering its first 8-bit depth depth (1/255, #010101), and its near-black rendering capabilities stay wonderful right down to its minimal brightness the place it could actually nonetheless render 2.4%-intensity (6/255) grey. Solely the iPhones have been able to doing this on a cell OLED, up till now. The iPhone OLEDs, too, carry shadows on the dim finish for higher near-black rendering; it’s at present a essential trade-off to maintain picture constancy viable in darkish viewing situations. Nonetheless, at minimal brightness, the Apple iPhones and the OnePlus 7 Professional are nonetheless superior in black clipping than the Google Pixel 4.

This can be a stunning growth because the LG panel within the Pixel 2 XL was infamous for abnormally-high black clipping. The Pixel Three additionally had an LG panel, and it confirmed enhancements in black clipping, nevertheless it was nonetheless noticeably larger than that of typical Samsung panels. I solely anticipated a marginal enchancment with the LG panel on the Pixel 4, however I’m really fairly shocked by how a lot the LG panel improved this time round.

Pixel Four HDR10 Playback

Whereas HDR content material on smartphones is usually nonetheless restricted to only Netflix and a few brief movies on YouTube, it’s at all times enjoyable to see the bleeding-edge capabilities of our little pocket computer systems. Supporting good HDR10 accuracy now may add a pleasant layer of future-proofing for the eventual proliferation of HDR content material — although whether or not it’s the HDR10 customary that’ll be dominant is but to be seen. I solely managed to have time to check HDR10 within the Google Pixel Four XL (and solely 8-bit intervals), and it does simply okay.

At a peak brightness of 600 nits, the Google Pixel Four XL does meet the HDR customary brightness of at the very least 540 nits for OLEDs. However in comparison with the 1200+ nits claimed on the Galaxy Be aware10 and the iPhone 11 Professional, the highlights on the Pixel Four XL appear dim. Moreover, the Google Pixel Four XL appears to remarkably undertrack the decrease 15% of its sign vary, rendering these important darkish scenes a lot darker than meant. It does present a easy roll-off into its peak brightness although, as an alternative of simply clipping.

Shifting ahead, the excellence of the Google Pixel Four XL’s colour accuracy extends on to its HDR Rec. 709 accuracy. Though it’s not reference-level, a ΔETP of three.Four continues to be excellent. Nonetheless, most HDR10 content material extends as much as DCI-P3, which is rather more demanding to precisely reproduce. The usual for HDR DCI-P3 is usually a nominal white stage of 1000 nits, and the Pixel Four XL is just not even able to getting that brilliant. In order anticipated, the Pixel Four XL can not cowl a great chunk of the HDR DCI-P3 gamut, and it breaks down at reproducing the upper interior colour mixtures (orange, pink, and purple).

Ultimate Ideas

This yr, Google closed the hole between the 2 shows greater than ever earlier than. Their calibrations match up rather more evenly, however now they each have particular person traits that forestall one show from being the clear superior. Though the Pixel Four XL might have colours that measure extra precisely, I’m hard-pressed to see the distinction at these scales. Moreover, I imagine that distinction is crucial think about an correct picture, and the Pixel Four constantly performs higher than the Pixel Four XL all through its brightness vary. The Pixel Four additionally has wonderful shadow rendering that rivals the iPhones’, and I’m a shopper of plenty of content material the place this issues. Nonetheless, the grayscale inconsistencies are noticeable and annoying, and it places me off the Pixel Four seeing totally different grey UI parts with totally different tints. Fortunately, my Pixel Four had wonderful show uniformity for darkish grey, however I’ve already seen many posts relating to regional display tints. And this leads into the show lottery, which I’m sure will nonetheless be a giant challenge for the LG panel on the Pixel Four this yr.

Shoppers paying $800+ shouldn’t be worrying about one thing like a dim show or a lottery in 2019, however that appears to be a recurring theme for Pixel units

And as anticipated, my greatest gripe with each shows is their poor brightness. I reside in California — a brilliant show is an absolute should through the summer time. I additionally sometimes maintain my telephone on a automobile mount whereas I’m driving, and I’ve discovered all Pixel telephones to be fairly poor for this due to their brightness. A brilliant display is simply an total a lot better expertise outdoor, and there’s no use for one of the best calibration on this planet when you have difficulties seeing it within the first place. It might additionally enhance the digicam expertise, which appears to be Google’s most important promoting level. Positive, its brightness is probably not a difficulty for others relying on what they count on from their telephone, however that doesn’t invalidate the difficulty for the various that see it as such.

It’s higher to have and never want, than to wish and never have.

-Not Google

OnePlus, an organization a lot smaller than Google, was in a position to safe next-gen panels from Samsung that will get simply as brilliant because the Galaxy Be aware10 and the iPhone 11 Professional, they usually launched the OnePlus 7T at about the identical time because the Pixel 4. The iPhone 11 Professional, which is the telephone that Google is attempting to straight compete with, was launched sooner than the Pixel Four with Samsung’s newest panels. Google ought to have positively been in a position to do the identical had they really made an trustworthy effort in utilizing one of the best elements that they’ll. It feels as if Google actually prides itself on discovering workarounds for {hardware} “bottlenecks,” however generally it simply looks like it’s to a fault — and in these instances, they need to simply use higher {hardware}.
