Slowly drag your finger to the bottom right corner without lifting. Try to move your finger slowly enough that you can count to 10 before reaching the opposite corner of the screen.

Under your Pixel 5 phone’s screen, at the top center, you can see a white dot. This white dot is your proximity sensor. When your proximity sensor is on, the dot shows through the display. The dot can blink or stay solid.

Your proximity sensor keeps your phone’s screen off while you hold your phone near your face during a call, when your screen is locked, and when used by certain apps. Keeping the screen off helps save battery and avoid accidental taps on the screen.

All Pixel phones have proximity sensors. Because the Pixel 5’s display goes almost to the edge, you can see the Pixel 5’s sensor under the screen. Check our Pixel 5 phone diagram.

The three green LEDs indicating 3.3, 5, or 12 V from the floppy, SATA, and 4 pin Molex power connectors are not an indication of a measurement "good" signal from an active device that is "measuring" the voltages. Rather, they are simply wired straight to the incoming voltages from the connected SATA, Floppy, or Molex plugs with a series current limiting resistor. It is not a "measurement" in the sense that the other voltages indicated on the LCD display are being measured. It is just a "dumb" indication that a voltage sort-of close to the required voltage is present, or that the wires are actually connected properly. The 3.3, 5, or 12 V lines could be off by a bit and the LEDs would still light up, but they would be brighter or darker than they would be with the correct voltage applied. You can look at the main LCD if you want to know the exact voltage coming out of those power supplies.

Also, this measurement unit does not load the power supply and draw a lot of power like a real operating computer will when plugged into the power supply. So, if the power supply has problems maintaining proper voltages operating under a load, this unit will not tell you that. But you could infer that problem if all the voltages showed OK using this tester, but the PC still won"t run properly (could be many other problems also ...).

Pixels are no stranger to top-end phone prices. Though all this time, it"s seemed that Google hadn"t yet released a true spiritual flagship that they were happy with—at least not until now with the Pixel 6 and Pixel 6 Pro. This year, it"s clear that Google"s new phones are the ones that the company takes pride in, but for all we know, that might just be all talk. So what better way to demonstrate the Pixel"s resurgence than to test out their effort and commitment to the display?

The Pixel 6 Pro comes equipped with a sharp 6.71-inch OLED, and it has the best display hardware that Google has put on a phone till date. It uses a high-end configuration from Samsung Display, although it"s a whole step down when compared to its latest generation of OLED. This is one of those shortcomings. But considering that phones with newer display tech are generally more expensive than the Pixel 6 Pro, I"d say that its price justifies the hardware. Regardless, the panel is more than capable of delivering stunning visuals, and the 120 Hz high refresh rate makes interacting with the phone super smooth. There"s also a curve on the sides of the display that phone makers love to tack on in an attempt to make their phone look more premium, but I"m not a fan of it.

The regular Pixel 6 uses a lower-resolution 6.40-inch Samsung panel. Although both phones are using updated OLEDs, the hardware on the Pixel 6 is actually a downgrade in some ways compared to last year"s Pixel 5. For the first time since the Pixel 2, Google is using an inferior rigid OLED display stack in their main phone lineup to cut costs. Compared to modern flexible OLEDs (like on the 6 Pro and on most flagship phones), the typical rigid display stack has lower screen contrast, fluctuant viewing angles, and appears more sunken into the display. On the upside, the Pixel 6 does get brighter, and it does appear sharper than the Pixel 5 despite having a lower pixel density (more on this later).

Seldom mentioned is the difference in the subpixels between PenTile OLEDs. Larger subpixels improve power efficiency and lengthen their longevity, which reduces burn-in. Higher-density screens require packing in smaller subpixels, thus there are advantages to accomodating a lower physical screen resolution. Note that this is completely different than sampling a screen at a lower render resolution, which does almost nothing for the battery outside of full-resolution gaming since the physical subpixels are still the same size.

Instead of decreasing the screen resolution, another option is to increase the panel"s fill factor, which is defined as the ratio of the subpixels" emissive area to the total display area. For lower-resolution OLEDs, this has the added benefit of improving pixel definition, which reduces apparent color fringing around well-defined edges in the screen. Starting with the Samsung Galaxy S21, Samsung Display began to produce 1080p panels with higher fill factors, increasing the relative size of the subpixel area by about 20%. To my eyes, this had completely eliminated color fringing on these panels, and they now look closer to their non-PenTile counterparts. For those that use their phone for VR, a higher fill factor also reduces the screen door effect.

Fortunately, the Pixel 6"s 1080p screen has a high fill factor, and I observe no color fringing with it. Its screen appears sharper than 1080p PenTile screens of the past, including the higher-density panel of the Pixel 5, so those that are coming from 1440p displays need not worry too much. The OLED on the 6 Pro, however, has a lower fill ratio, so efficiency gains can be had with a better display design. Though as it stands, Apple is currently the only company that optimizes for both resolution and fill factor, with iPhone OLEDs having the largest subpixels out of any phone.

To obtain quantitative color data from smartphones, display test patterns are staged and measured using an X-Rite i1Display Pro metered by an X-Rite i1Pro 2 spectrophotometer in its high-resolution 3.3nm mode. The test patterns and device settings used are corrected for various display characteristics and potential software implementations that may alter desired measurements. Measurements are performed with arbitrary display adjustments disabled unless mentioned otherwise.

The primary test patterns are constant powerpatterns (sometimes calledequal energypatterns), correlating to an average pixel level of about 42%, to measure the transfer function and grayscale precision. It’s important to measure emissive displays not only with constant average pixel level but also with constant power patterns since their output is dependent on the average display luminance. Additionally, a constant average pixel level does not inherently mean constant power; the test patterns I use are of both. A higher average pixel level closer to 50% is used to capture the midpoint performance between both the lower pixel levels and the higher pixel levels since many apps and webpages contain white backgrounds that are higher in pixel level.

ΔEITP normally considers luminance error in its computation, since luminance is a necessary component to completely describe color. However, since the human visual system interprets chromaticity and luminance separately, I hold our test patterns at a constant luminance and do not include the luminance (I/intensity) error in our ΔEITP values. Furthermore, it is helpful to separate the two errors when assessing a display’s performance because, just like with our visual system, they pertain to different issues with the display. This way, we can more thoroughly analyze and understand the performance of a display.

Contrast, grayscale, and color accuracy are tested throughout the display’s brightness range. The brightness increments are spaced evenly between the maximum and minimum display brightness in PQ-space. Charts and graphs are also plotted in PQ-space (if applicable) for proper representation of the actual perception of brightness.

HDR test patterns are tested against ITU-R BT.2100 using the Perceptual Quantizer (ST 2084). HDR sRGB and P3 patterns are spaced out evenly with sRGB/P3 primaries, an HDR reference white level of 203 cd/m2 (ITU-R BT.2408), and a PQ signal level of 58% for all the color patterns. All HDR patterns are tested at 20% APL with constant power test patterns.

If picture fidelity is a priority, the Natural mode is the Pixel"s color-accurate profile. The profile targets the full sRGB color space (gamut, white point, and tone response) while Android"s color management system handles wide-gamut P3 content in apps that support it. Internally, Google is now also targeting Display P3 as the phone"s default composition data space, which is a small step in maturing their color management system.

For those that are not satisfied with the white balance of their Pixel, Google, unfortunately, does not provide any option to tune that aspect of the display (outside of Night Light). Google formerly had a feature called Ambient EQ on the Pixel 4 which automatically matched the white balance of the screen to the user"s ambient lighting, but the company scrapped it in its future phones for reasons unknown.

In terms of screen brightness, both the Pixel 6 and the Pixel 6 Pro perform nearly identical to each other, and they both get bright enough to use the phone under sunlight. With auto-brightness enabled, both phones get up to about 750–770 nits for fullscreen white, boosting up to 1000–1100 nits for content with lower average light levels ("APL"). Sadly the Pixel 6 and 6 Pro can only maintain their high brightness mode for five minutes at a time out of every thirty minutes, so using the phone extensively outside may not be ideal. After five minutes, the phone display will ramp down to about 470 nits, which is both phones" maximum manual brightness when auto-brightness is disabled.

Apart from peak brightness, display tone mapping also plays a big role in improving a screen"s legibility under sunlight. This will be covered more later on, but in short, the Pixel 6 and Pixel 6 Pro does boost shadow tones to help out with outdoor viewing.

Although the Pixel 6 has 2043 brightness values, those values are mapped linearly to its display brightness. This means that the spacing of brightness between those values is not perceptually uniform, since the human perception of brightness scales somewhat logarithmically, rather than linearly, in response to screen luminance nits. In Android 9 Pie, Google altered the Pixel"s brightness slider so that it would scale logarithmically instead of linearly for the reason that I just mentioned. However, this only changed how the position on the brightness slider mapped to the system brightness value, which is still internally linear.

Quickly touching on display power: When focusing on fullscreen display nits per watt, the Pixel 6 Pro consumes substantially more power than the Pixel 6 at high brightness. This is somewhat expected since the Pro has a slightly larger display and a higher resolution (read: smaller emissive pixel area), though I did not expect the difference to be this dramatic. Adding in the Samsung Galaxy S21 Ultra as another data point, it consumes less power than both Pixels despite having a larger screen, which showcases the impeccable efficiency gains of Samsung"s next-gen OLED emitters. The discrepancy in variable refresh rate was not tested.

At their dimmest setting, the Pixel 6 Pro paints a much more tonally balanced screen. In its Natural mode, the Pixel 6 Pro is one of the best-performing low brightness OLEDs on any phone. I claimed the same thing for last year"s Pixel 5, which had impeccable shadow tone control. Compared to it, the Pixel 6 Pro performs similarly, though this year"s display is just slightly worse near black. While the Pixel 5 was able to render its first bit step out of black (1/255) at all brightness levels, the Pixel 6 Pro can only do so at high brightness. It does globally render the very next step, however, and in my book, that"s still fantastic. The Pixel 5"s shadows were also a bit lighter overall in low light, but in my opinion it made things look a little too flat, and I now prefer the look of the 6 Pro.

Two colors from different displays that measure the same exact chromaticity don"t necessarily appear identical in color. The fact of the matter is that current methods of color measurement don"t provide a definitive assessment for color matching. As it turns out, the difference in spectral distributions between OLEDs and LCDs creates a disagreement in the appearance of their white points. More precisely, the color of white on OLEDs will typically appear yellowish-green compared to an LCD display that measures identically. This is known as metameric failure, and it"s been widely acknowledged to occur with wide-gamut displays such as OLEDs. The standard illuminants (e.g. D65) have been defined with spectral distributions that match closer to that of an LCD, so the technology is now used as a reference. For this reason, an offset towards magenta is needed for the white point of OLEDs to perceptually match the two display technologies.

Now, I"m not saying that metameric failure is the reason why the Pixel 6 (Pro) displays measure towards magenta, but there"s a point to be made about looking at just colorimetric measurements alone. For reference, this is how the white point of the Pixel 6 Pro measures when it"s perceptually color-matched to my calibrated LCD monitor. The difference is massive. There have been many attempts in methodologically transferring over the perceptual appearance, but none have been comprehensive enough to cover every emerging display type—matching by eye is quite literally the best way to do this at the moment. Nevertheless, accurate measurements to any standard allow for predictability if adjustments are to be made, which is a critical attribute for any electrical component.

Excellent tone control, precision, and color accuracy carries over to HDR10 on the Pixel 6 Pro. The ST.2084 standard HDR tone response curve is faithfully reproduced along with incredibly consistent color temperature all throughout its grayscale. This assures that the white balance and contrast of every scene can replicate the creator"s visual intent, at least up to 650 nits. Most HDR content that is currently being delivered through streaming platforms is mastered or optimized for a maximum headroom of 1,000 nits for highlights. The Pixel 6 Pro is able to get up to 800 nits fullscreen brightness, but a lack of metadata-aware tone mapping brings the usable in-content peak down to about 650 nits. While the 350-nit deficit may seem substantial, not many scenes in practice are graded much brighter.

The gotcha is that all the above assume a viewing environment of 5 lux, which is the status quo for HDR10. This is considerably dim for casual watching, and most people in actuality will watch things in a brighter setting. Furthermore, standard HDR10 replication is calibrated for maximum system brightness, so if you intend to watch a show in HDR10 inside a brighter room, the experience won"t be optimal since the display brightness can"t be set any higher. HDR10 is also implemented this way in most TVs, not just on the Pixel 6 or on Android, but newer TVs also offer adaptive adjustments to the HDR tone mapping to compensate for brighter environments. The Pixel 6"s 650-nit effective peak along with its lack of adaptive tone mapping means that it can"t deliver the same strong HDR performance outside of a dimly lit room.

For its highest-end handset, Google delivers some of the best color reproduction and image consistency that you can find on any consumer display. With the Pixel 6 Pro, you can be certain that you"re seeing all the picture details at any brightness level, be it dim or bright. On the contrary, the color tuning may be the reason why some people won"t like it. Even in its most vibrant color mode, the display still behaves on the more color-accurate side, so those that prefer a high-saturation appearance may be left wanting more. Additionally, the Pixel 6 Pro doesn"t carry the brightest or the most efficient OLED tech, but its current capabilities are perfectly adequate and well worth its price tag. It"s understandable that people would want the absolute best panel available from the best phone that Google offers, but the Pixel 6 Pro is just not priced in that manner.

Speaking of price, the cheaper phone, unsurprisingly, uses a cheaper display. And by cheaper, I do mean cheap. From crude viewing angles to irregular screen uniformity and grayscale tinting, the OLED on the Pixel 6 is very much a budget-level phone experience—one that you would expect from their Pixel A-series. For what"s supposed to be one of Google"s two strongest offerings, the choice of OLED on the Pixel 6 makes it feel like an unpolished product, and in my opinion, it completely cheapens the brand. We don"t find this level of compromise on the display of any other flagship "non-Pro" variants from the competition.

Despite the rest of the handset feeling quite premium, the screen is just too important of a component to skimp out on. Many people have criticized Apple for adopting OLED so late inside their base models, but in its defense, using the Pixel 6 made it understandable why Apple had decided not to just include any cheap rigid OLED in their phones. They simply lack the refinement that is expected from a premium handset. For its price point, I don"t think it could be helped; by undercutting the competition by $100–$200 USD, the Pixel 6 inevitably had to make some sort of glaring sacrifice. So, rather than just being a well-priced premium phone, what this showed me was that the Pixel 6 is truly more of a mid-range device, in a tier that is more similar to Apple"s "R"-series or Samsung"s "FE" variant.

Within the Pixel software, some accommodations could have been made to enhance the user experience. For starters, improvements to the auto-brightness are sorely needed, as its transitions turn out to be jarring more often than not. I would also appreciate the return of AmbientEQ, which was the automatic white balance feature in the Pixel 4. Manual adjustments to the screen white balance would also be helpful, which could be used to tune the screen color temperature to your taste, or even to compensate for the metameric failure.

Android phones are great devices for those who like to have a lot of customization options and control over their device’s operating system. Your Android device comes with pre-installed and automatically activated features that ensure your smartphone’s security and functionality.
