For television, the display aspect ratio (DAR) is shown, not the storage aspect ratio (SAR); analog television does not have well-defined pixels, while several digital television standards have non-square pixels.

The below distinguish SAR (aspect ratio of pixel dimensions), DAR (aspect ratio of displayed image dimensions), and the corresponding PAR (aspect ratio of individual pixels), though it currently contains some errors (inconsistencies), as flagged.

This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g. red indicates a 4:3 ratio).

The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays.

One use of the term display resolution applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pixels creating the display (e.g. 1920 × 1080). A consequence of having a fixed-grid display is that, for multi-format video inputs, all displays need a "scaling engine" (a digital video processor that includes a memory array) to match the incoming picture format to the display.

For device displays such as phones, tablets, monitors and televisions, the use of the term display resolution as defined above is a misnomer, though common. The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920 × 1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not the total number of pixels. In digital measurement, the display resolution would be given in pixels per inch (PPI). In analog measurement, if the screen is 10 inches high, then the horizontal resolution is measured across a square 10 inches wide.NTSC TVs can typically display about 340 lines of "per picture height" horizontal resolution from over-the-air sources, which is equivalent to about 440 total lines of actual picture information from left edge to right edge.

Some commentators also use display resolution to indicate a range of input formats that the display"s input electronics will accept and often include formats greater than the screen"s native grid size even though they have to be down-scaled to match the screen"s parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 × 768 pixel array). In the case of television inputs, many manufacturers will take the input and zoom it out to "overscan" the display by as much as 5% so input resolution is not necessarily display resolution.

The eye"s perception of display resolution can be affected by a number of factors – see image resolution and optical resolution. One factor is the display screen"s rectangular shape, which is expressed as the ratio of the physical picture width to the physical picture height. This is known as the aspect ratio. A screen"s physical aspect ratio and the individual pixels" aspect ratio may not necessarily be the same. An array of 1280 × 720 on a 16:9 display has square pixels, but an array of 1024 × 768 on a 16:9 display has oblong pixels.

An example of pixel shape affecting "resolution" or perceived sharpness: displaying more information in a smaller area using a higher resolution makes the image much clearer or "sharper". However, most recent screen technologies are fixed at a certain resolution; making the resolution lower on these kinds of screens will greatly decrease sharpness, as an interpolation process is used to "fix" the non-native resolution input into the display"s native resolution output.

While some CRT-based displays may use digital video processing that involves image scaling using memory arrays, ultimately "display resolution" in CRT-type displays is affected by different parameters such as spot size and focus, astigmatic effects in the display corners, the color phosphor pitch shadow mask (such as Trinitron) in color displays, and the video bandwidth.

Most television display manufacturers "overscan" the pictures on their displays (CRTs and PDPs, LCDs etc.), so that the effective on-screen picture may be reduced from 720 × 576 (480) to 680 × 550 (450), for example. The size of the invisible area somewhat depends on the display device. Some HD televisions do this as well, to a similar extent.

Computer displays including projectors generally do not overscan although many models (particularly CRT displays) allow it. CRT displays tend to be underscanned in stock configurations, to compensate for the increasing distortions at the corners.

Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon.

Progressive scanning (alternatively referred to as noninterlaced scanning) is a format of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video.

Many personal computers introduced in the late 1970s and the 1980s were designed to use television receivers as their display devices, making the resolutions dependent on the television standards in use, including PAL and NTSC. Picture sizes were usually limited to ensure the visibility of all the pixels in the major television standards and the broad range of television sets with varying amounts of over scan. The actual drawable picture area was, therefore, somewhat smaller than the whole screen, and was usually surrounded by a static-colored border (see image below). Also, the interlace scanning was usually omitted in order to provide more stability to the picture, effectively halving the vertical resolution in progress. 160 × 200, 320 × 200 and 640 × 200 on NTSC were relatively common resolutions in the era (224, 240 or 256 scanlines were also common). In the IBM PC world, these resolutions came to be used by 16-color EGA video cards.

One of the drawbacks of using a classic television is that the computer display resolution is higher than the television could decode. Chroma resolution for NTSC/PAL televisions are bandwidth-limited to a maximum 1.5MHz, or approximately 160 pixels wide, which led to blurring of the color for 320- or 640-wide signals, and made text difficult to read (see example image below). Many users upgraded to higher-quality televisions with S-Video or RGBI inputs that helped eliminate chroma blur and produce more legible displays. The earliest, lowest cost solution to the chroma problem was offered in the Atari 2600 Video Computer System and the Apple II+, both of which offered the option to disable the color and view a legacy black-and-white signal. On the Commodore 64, the GEOS mirrored the Mac OS method of using black-and-white to improve readability.

Programs designed to mimic older hardware such as Atari, Sega, or Nintendo game consoles (emulators) when attached to multiscan CRTs, routinely use much lower resolutions, such as 160 × 200 or 320 × 400 for greater authenticity, though other emulators have taken advantage of pixelation recognition on circle, square, triangle and other geometric features on a lesser resolution for a more scaled vector rendering. Some emulators, at higher resolutions, can even mimic the aperture grille and shadow masks of CRT monitors.

In 2002, 1024 × 768 eXtended Graphics Array was the most common display resolution. Many web sites and multimedia products were re-designed from the previous 800 × 600 format to the layouts optimized for 1024 × 768.

In 2010, 27-inch LCD monitors with the 2560 × 1440 resolution were released by multiple manufacturers, and in 2012, Apple introduced a 2880 × 1800 display on the MacBook Pro. Panels for professional environments, such as medical use and air traffic control, support resolutions up to 4096 × 21602048 × 2048 pixels).

The following table lists the usage share of display resolutions from two sources, as of June 2020. The numbers are not representative of computer users in general.

In recent years the 16:9 aspect ratio has become more common in notebook displays. 1366 × 768 (HD) has become popular for most low-cost notebooks, while 1920 × 1080 (FHD) and higher resolutions are available for more premium notebooks.

When a computer display resolution is set higher than the physical screen resolution (native resolution), some video drivers make the virtual screen scrollable over the physical screen thus realizing a two dimensional virtual desktop with its viewport. Most LCD manufacturers do make note of the panel"s native resolution as working in a non-native resolution on LCDs will result in a poorer image, due to dropping of pixels to make the image fit (when using DVI) or insufficient sampling of the analog signal (when using VGA connector). Few CRT manufacturers will quote the true native resolution, because CRTs are analog in nature and can vary their display from as low as 320 × 200 (emulation of older computers or game consoles) to as high as the internal board will allow, or the image becomes too detailed for the vacuum tube to recreate (i.e., analog blur). Thus, CRTs provide a variability in resolution that fixed resolution LCDs cannot provide.

A digital image is nothing more than data—numbers indicating variations of red, green, and blue at a particular location on a grid of pixels. Most of the time, we view these pixels as miniature rectangles sandwiched together on a computer screen. With a little creative thinking and some lower level manipulation of pixels with code, however, we can display that information in a myriad of ways. This tutorial is dedicated to breaking out of simple shape drawing in Processing and using images (and their pixels) as the building blocks of Processing graphics.

Hopefully, you are comfortable with the idea of data types. You probably specify them often—a float variable "speed", an int "x", etc. These are all primitive data types, bits sitting in the computer"s memory ready for our use. Though perhaps a bit trickier, you hopefully also use objects, complex data types that store multiple pieces of data (along with functionality)—a "Ball" class, for example, might include floating point variables for location, size, and speed as well as methods to move, display itself, and so on.

When displaying an image, you might like to alter its appearance. Perhaps you would like the image to appear darker, transparent, blue-ish, etc. This type of simple image filtering is achieved with Processing"s tint() function. tint() is essentially the image equivalent of shape"s fill(), setting the color and alpha transparency for displaying an image on screen. An image, nevertheless, is not usually all one color. The arguments for tint() simply specify how much of a given color to use for every pixel of that image, as well as how transparent those pixels should appear.

For the following examples, we will assume that two images (a sunflower and a dog) have been loaded and the dog is displayed as the background (which will allow us demonstrate transparency.)PImage sunflower = loadImage("sunflower.jpg");

In the above example, because the colors are set randomly, we didn"t have to worry about where the pixels are onscreen as we access them, since we are simply setting all the pixels with no regard to their relative location. However, in many image processing applications, the XY location of the pixels themselves is crucial information. A simple example of this might be, set every even column of pixels to white and every odd to black. How could you do this with a one dimensional pixel array? How do you know what column or row any given pixel is in?

In programming with pixels, we need to be able to think of every pixel as living in a two dimensional world, but continue to access the data in one (since that is how it is made available to us). We can do this via the following formula:Assume a window or image with a given WIDTH and HEIGHT.

Now, we could certainly come up with simplifications in order to merely display the image (for example, the nested loop is not required, not to mention that using the image() function would allow us to skip all this pixel work entirely.) However, example 15-7 provides a basic framework for getting the red, green, and blue values for each pixel based on its spatial orientation (XY location); ultimately, this will allow us to develop more advanced image processing algorithms.

All of our image processing examples have read every pixel from a source image and written a new pixel to the Processing window directly. However, it"s often more convenient to write the new pixels to a destination image (that you then display using the image() function). We"ll demonstrate this technique while looking at another simple pixel operation: threshold.

A threshold filter displays each pixel of an image in only one of two states, black or white. That state is set according to a particular threshold value. If the pixel"s brightness is greater than the threshold, we color the pixel white, less than, black. In the code below, we use an arbitrary threshold of 100.

In previous examples, we"ve seen a one-to-one relationship between source pixels and destination pixels. To increase an image"s brightness, we take one pixel from the source image, increase the RGB values, and display one pixel in the output window. In order to perform more advanced image processing functions, we must move beyond the one-to-one pixel paradigm into pixel group processing.

You may be thinking: "Gosh, this is all very interesting, but seriously, when I want to blur an image or change its brightness, do I really need to write code? I mean, can"t I use Photoshop?" Indeed, what we have achieved here is an merely an introductory understanding of what highly skilled programmers at Adobe do. The power of Processing, however, is the potential for real-time, interactive graphics applications. There is no need for us to live within the confines of "pixel point" and "pixel group" processing.

Following are two examples of algorithms for drawing processing shapes. Instead of coloring the shapes randomly or with hard-coded values as we have in the past, we select colors from pixels inside of a PImage object. The image itself is never displayed; rather, it serves as a database of information that we can exploit for a multitude of creative pursuits.

In this first example, for every cycle through draw(), we fill one ellipse at a random location onscreen with a color taken from its corresponding location in the source image. The result is a basic "pointillist-like" effect:

Have you ever left your TV or monitor on for days, stuck on the same image? You return to your screen, only to find an image burned into the display. No matter what you do, it won"t go away. It is a permanent image burn.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

Before flat-screens and crystal displays, most TVs and monitors featured CRT (Cathode Ray Tube) technology. In CRTs, individual pixels comprise a red, blue, and green phosphor component. Depending on the intensity of each phosphor component, the pixel appears to the human eye as a unique color.

Plasma displays use plasma, a gaseous substance containing free-flowing ions. When the plasma is not in use, the particles in the plasma are uncharged and display nothing. With the introduction of an electric current, the ions become charged and begin colliding, releasing photons of light.

This is a very simplified version of how a plasma screen works. However, the main thing to understand is that plasma screens use phosphor material (like CRTs) to turn those photons into images.

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

Plasma screens also suffer from phosphor deterioration. Plasma burning occurs when pixels on the screen are damaged through long exposure. The phosphor loses its intensity and only shows the light it was fed repeatedly. In this case, the still image, which causes the burn.

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

The other thing to consider is that LED and OLED image burn-in, when it happens, is irreversible. That"s because of how LED and OLED screens work. Individual pixels within an LED display decay when they emit light.

Under normal use, an LED, OLED, or QLED screen won"t suffer image burn. However, if you leave your screen on a single channel for hours every day, then burn-in can become an issue, as it would with almost any screen.

Issues arise when a screen shows a single news channel 24 hours a day, every day, causing channel logos to burn-in, along with the outline of the scrolling news ticker and so on. News channels are a well-known source of television burn-in, no matter the screen type.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

My personal rule of thumb is to turn off the display if I plan on being away for more than 15 minutes. That way, it is difficult to get caught out, plus you save yourself money on electricity costs and monitor or TV wear and tear.

Another prevention method is to reduce screen contrast as much as you can. Unfortunately, most screens aren"t calibrated correctly, often pushing the contrast and brightness settings too high.

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

Other modern screens feature built-in screen refresh functions that the manufacturer will advise using to remove image retention and image burn issues.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

If you have television burn-in, you can attach a laptop to your TV using an HDMI cable, extend your desktop to the television, and share the white screensaver. Hopefully, that will shift your television burn-in.

During semester one of this year I came across a new style of art called Pixel Art. I was sitting in one of the classrooms of Bassendean Primary School listening to a presenter speak. As I looked around the room, I saw some Pixel Art self-portraits displayed on the walls. After having a good look at the amazing work the students created, I did some research into the Pixel Art niche.

Pixel Art is a form of digital art that focuses on one thing, the humble square shaped pixel. Your computer monitor, smart phone and even the old Nokia 3310 has a liquid crystal display (LCD). LCD screens are made up of thousands of pixels. Pixels are the tiny squares that change colour in response to the image displayed on your screen. If you squint hard enough, you can probably see them on the device you are currently reading this blog on.

Once I had an impressive collection of Pixel Art images on my computer, I then uploaded these pictures onto Connect. I was pretty strict with making sure that my students only used Connect to access these ‘teacher approved’ pictures. On a side note, Google’s kid friendly search engine Kiddleblocked out all images of Pixel Art. So unfortunately this search engine, which is usually very useful, won’t be of any help.

Unfortunately BRIK does not allow you to save your work; however, once students have created their single sprite image, they can always screenshot this image as a way of saving it.

BRIK also has an online community and there is a gallery for Pixel Art. I haven’t come across any inappropriate Pixel Art images on BRIK; however, make sure you have a closer look at this part of their website. Please keep in mind that BRIK is a company that also sells BRIK related product such as greeting cards, laptop display panels and marble runs.

Even though I finished this unit of work 10 weeks ago, students regularly ask me if we can create Pixel Art images again. I occasionally find students of mine making Pixel Art images in their spare time and I still come across students who bring in images that they have created at home. Just on this fact alone, you could say that this unit of work was very successful. It’s an absolute joy to see students using the skills you have taught them; it’s even better when you see them use this knowledge to make even more advanced Pixel Art images and animated character sprites.

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?

This time around, Google changed up its release formula, opting for just one general size—big—for its two main phones. The handsets are now differentiated by their feature set, with the more premium of the two Pixel 6"s adopting the "Pro" moniker. In terms of pricing, Google surprised us with numbers that undercut its previous phones, as well as much of the competition"s, for both Pixels" respective tiers within the smartphone market. Questionably, corners had to have been cut somewhere. With display components usually making up the largest share in a phone"s bill of materials, that"s usually where you"ll first find shortcomings.

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).

Rigid OLEDs are an older construction that is now usually only used in budget phones. The main difference is that a rigid OLED includes a thicker glass encapsulation and substrate, while flexible OLEDs utilize a thin-film encapsulation and a bendable plastic substrate. The elastic nature of flexible OLEDs not only makes them more durable and moldable than rigid OLEDs, but it also allows for some optical advantages. Thinner encapsulation allows the physical pixels to appear closer to the cover glass, giving flexible OLEDs a more laminated look. Also, on rigid stacks, the refraction of the light transmitted through the glass layers causes unwanted rainbow viewing angles that you simply don"t see on flexible OLEDs. Lastly, not all "infinite contrast ratios" are made equal: newer flexible OLED display stacks contain darker internal materials, imposing deeper blacks than those of rigid OLEDs.

On the Pixel 6 Pro, higher-efficiency hybrid oxide transistors support the backplane, which greatly enhances an OLED"s driving stability. This is the catalyst in enabling a true variable refresh rate, saving power as it allows pixels to hold their charge for much longer between refreshes. Since they have a low rate of discharge, oxide driving TFTs can pulse at lower currents compared to an LTPS TFT to achieve the same steady-state luminance, which further saves battery and improves calibration precision. Anecdotally, every phone that I"ve used with an LTPO panel has had near-flawless panel uniformity and very little gray tinting in low light, and I believe much of that can be also be attributed to the improved stability of the hybrid oxide backplane.

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.

The color difference metric used is ΔETP (ITU-R BT.2124), which is an overall better measure for color differences than ΔE00 that is used in earlier reviews and is still currently being used in many other sites’ display reviews. Those that are still using ΔE00 for color error reporting are encouraged to update to ΔEITP.

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.

ΔETP values are roughly 3× the magnitude of ΔE00 values for the same color difference. A measured color error ΔETP of 1.0 denotes the smallest value for a just-noticeable-difference for the measured color, and the metric assumes the most critically adapted state for the observer so as not to under-predict color errors. A color error ΔETP less than 3.0 is an acceptable level of accuracy for a reference display (suggested from ITU-R BT.2124 Annex 4.2), and a ΔETP value greater than 8.0 can be noticeable at a glance, which I’ve concluded empirically.

By default, Adaptive mode is selected out of the box. Both Adaptiveand Boostedmodes increase color saturation just slightly, with the main difference being that Adaptive mode also uses higher contrast. Compared to the vivid profile of many other smartphones, the Adaptive mode is not as vibrant, and some people may even struggle to see the difference between Adaptive and Natural. All three profiles target a D65 white point, which might appear warm/yellow to those that aren"t accustomed to color-calibrated displays.

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.

When set to their dimmest brightness setting, the Pixel 6 and Pixel 6 Pro can get down to about 1.8–1.9 nits, which is typical of most, but not all OLED phones (namely OnePlus). At this brightness, the default Adaptive profile on both phones crushes near-black colors due to the profile"s steeper contrast curves. Natural mode exhibits lighter shadows, and on the Pixel 6 Pro the profile retains distinct shadow details with very little black clipping in low light. The Pixel 6, on the other hand, struggles a bit more with near-black colors, especially in its 90 Hz state.

Before the Pixel 6, Google only reserved 255 distinct brightness values to control the display brightness. Even if all brightness values were to be efficiently spaced out, the resolution simply wasn"t enough to create perfectly smooth transitions. Now with the Pixel 6, Google increased the internal number of brightness values up to 2043 between 2 nits and 500 nits. That seems like it should be sufficient, but there are two important details: the mapping of those brightness values, and how the Pixel transitions through those brightness values.

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.

Even with the higher brightness resolution of the Pixel 6, jitters can be seen between the brightness values below about 30% system brightness. For this inherent reason, the Pixel"s transition in display luminance can appear jumpy when the auto-brightness moves around in low light. The jitteriness is exacerbated by the speed and the behavior of the Pixel"s auto-brightness transitions, which steps linearly through display luminance at a constant pace that reaches max brightness from minimum brightness in one second—or about 500 nits per second. This makes any auto-brightness transition virtually instantaneous for small-to-medium adjustments.

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.

A general rule of thumb in calibrating a display is to target a gamma power of 2.4 for dark rooms, or 2.2 for everywhere else. Smartphones are used in all sorts of viewing conditions, so they typically fall in the latter category. Hence, most phones target a gamma power of 2.2 for their standard calibrated display modes. This is what the Pixel had always done, but it"s a little different this year on the Pixel 6 and Pixel 6 Pro.

What makes this interesting is that I"m not sure Google even intended for this behavior. Samsung also ships phones with the sRGB tone curve, though only on their Exynos variants—the Snapdragon models still use gamma 2.2. The Exynos display pipeline inside the Pixels" Tensor SoC is likely responsible for decoding RGB triplets with the sRGB transfer function.

When high brightness mode triggers under a sunny day, the displays will bump up the shadows, with the Pro phone being capable of being tuned a bit brighter. This helps improve the visibility of image details in brighter conditions without compromising the image quality.

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.

Within the same conditions, the non-Pro Pixel does not compete. The cheaper display renders steep shadows that clip a little more near black, and in Adaptive mode, the Pixel 6 becomes a mottled mess at minimum brightness. For this reason, I cannot recommend the profile on Pixel 6.

Nominally, both displays strike very similar white points that measure decently accurate to D65/6504 K. Both my units erred slightly on the magenta side, though I have no qualms with this as I"ll explain later.

Under the surface, the two phones actually perform vastly different when it comes to color precision. The Pixel 6 Pro maintains the color of its white throughout its grayscale and throughout its brightness range, with the exception of high-brightness mode where the tint in darker colors will likely be masked by sunlight. The Pixel 6, on the other hand, progressively tints towards magenta the lower the color tone intensity. A mild flicker was also visible when the Smooth Display auto-switched between 90 Hz and 60 Hz, but on my sample, the effect isn"t too noticeable. Lastly, on my unit, the non-uniform grayscale distribution is painfully obvious at lower brightness.

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.

The formula for good color accuracy is quite simple: accurate tone mapping plus an accurate white point. The previous sections of this review can almost entirely deduce the rest of the displays" color mixing performance. Pretty charts and quantitative verification are always nice though, so here they are.

Natural mode on both phones demonstrates fine-tuned color accuracy, with average color errors ΔETP less than 3.0, and maximum color errors ΔETPless than 10.0. These values are sufficient enough for a reference display, though it"s important to note that these color measurements were taken at 75% tone intensity; the poor color precision on the cheaper Pixel 6 display means that it"s expected to perform worse at lower tone intensities, while the Pro display remains accurate independent of tone intensity. Besides that, there is some mild skewing with more-complex color mixtures, such as with purple and orange, due to the different tone response curve that Google is using. No doubt that if it stuck with gamma 2.2, the Pixel 6 and Pixel 6 Pro would measure even more accurately, though the difference would mostly be academic.

In high-brightness mode, the displays will slightly crank up the color saturation to overcome the saturation loss from viewing glare. This together with the contrast lightness boost should help the display look more accurate under sunlight.

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.

As for the regular Pixel 6, it"s still capable of delivering brilliant visuals, just without as much polish. Scenes can vary in white balance on the cheaper OLED due to lower-brightness tinting, and image contrast is generally a little steeper. Shadow definition is also not as polished as on the Pro display.

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.

Overall, I"m torn on whether I like the direction that Google has taken for the displays of its two main phones. Of course, everyone would want them both to be a bit better—a slightly brighter display for the 6 Pro and a more refined OLED for the regular 6—but Google"s pricing has made it difficult to ask for more. At least for the Pro phone, I genuinely believe that you"re getting your money"s worth. But for the upper mid-ranged Pixel 6, I feel that it"s priced in a guttered region where it"s not priced high enough to afford a display that sets it apart from those on budget phones. If Google priced the Pixel 6 about $100 higher, but with a polished flexible OLED to boot, I believe that Google"s base model could be much more successful.

The Pixel 5 isn"t quite worth its high price, especially since its software support window ends soon (October 2023). Amazon currently sells the Pixel 4A 5G for the same price as the Pixel 6A, and while it"s a good phone, it should be cheaper. You"re better off sticking with the Pixel 6A. As for older Pixels, they"re not worth picking up. They"re just too old (and the Pixel 4 suffers from poor battery performance). Many of those devices will stop getting software updates soon if they haven"t already. Buy one of the newer models.

You get only one screen protector here and it"s very expensive. That"s because Zagg claims that the protector is five times as strong as traditional screen protectors. I haven"t seen too many scuffs on my Pixel 6A yet, but take this with a grain of salt. It"s easy to apply with the included application tool, but Zagg doesn"t include a squeegee at this price so you"ll have to use your fingers to push the air bubbles out.

Of the Pixels we recommend in this guide, wireless charging is available only on the Pixel 6, Pixel 6 Pro, Pixel 7, and Pixel 7 Pro. Google"s very own Pixel Stand is one of the best wireless chargers around because it"s simple. The base doesn"t slide around, the phone stays put, and it enables some fun features, like turning the screen into a digital photo frame and quick access to Google Assistant. It"s made of 39 percent recycled materials, with mostly eco-friendly packaging too. Our Best Wireless Chargers guide has more options. It"s also available at Best Buy.

This charging adapter is all you need to recharge your Pixel, whichever model you have. The newest high-end Pixel phones don"t come with chargers in the box, so if you don"t have any spare USB-C chargers, it"s worth picking one up. This one"s prongs don"t fold up, but it"s still really compact.

Retro games with simple mechanics and pixelated graphics can evoke fond memories for veteran gamers, while also being approachable to younger audiences. Nowadays, many games are labeled as “retro”, but it takes effort and planning to create a title that truly has that nostalgic look and feel. That’s why we’ve invited the folks from Mega Cat Studios to help us talk about the topic. In this blog post, we’ll be covering everything you need to create authentic art for NES-style games, including important Unity settings, graphics structures, and color palettes. Get our sample project and follow along!

With assets prepared, we can set our camera up to be “pixel-perfect”. A pixel-perfect result will look clean and crisp. Telltale signs of pixel art which aren’t displayed as pixel-perfect includes blurriness (aliasing), and some pixels appearing rectangular when they should be square.

First, I recommend checking ‘Run In Edit Mode’ and setting the display aspect ratio in the Game view to ‘Free Aspect’ so you can resize the game view freely. The component will display helpful messages in the game view explaining if the display is not pixel-perfect at any given resolution.

Reference Resolution - Set this to the resolution that you intend all of your assets to be viewed at. If you want a retro look, this usually means a very small resolution. For example, the native resolution for the Sega Genesis is 320x224. When porting a game from Sega Genesis, we would use a reference resolution of 320x224. For general 16:9 usage, 320x180, as well as, 398x224 (if you want to keep the vertical resolution instead) should work well.

Upscale Render Texture - This causes the scene to be rendered at as close to the reference resolution as possible and then be upscaled to the fit the actual display size. Because this setting results in a filled screen, we recommend it if you want a full-screen pixel-perfect experience with no margins. ‘Upscale Render Texture’ will also significantly affect how sprites look when rotated.

Crop Frame (X and Y) - This crops the viewed region of worldspace to exactly match the reference resolution, and adds black margins to the display to fill the gaps at the edges of the screen.

Stretch Fill - Becomes available if you enable both x and y for Crop Frame. This causes the camera to scale to the game view to fit the screen in a way that preserves aspect ratio. Because this scaling won’t happen only in whole number multiples of the reference resolution, it will cause pixel-perfectness to be lost at any resolution which is not a whole number multiple of the reference resolution. The advantage here is that even though you lose pixel-perfectness for many resolutions, you won’t have the black bar margins and will instead have a fully filled screen. Note that although blurring often occurs from stretch fill, the usual alert display message does not show up.

In Unity’s toolbar, you can go under Edit > Project Settings > Player and limit the aspect ratios that the game will support. If you find a particular configuration works just as you want in the ratio you’re targeting but looks bad in some particular aspect ratios, you can prevent the window from being at those ratios here. However, keep in mind that not all users will have a display setup that will work well with your limitations, so this is not recommended. Instead, enable cropping so these users will have margins, rather than having to play in a res
