A good monitor is expensive. But its impact will be lost if you don"t take the pain to carefully (and intermittently) calibrate your monitor. The colors on the screen may not be the exact match of what they actually are.

To open the Display Color Calibration tool, press Windows + S or open the Start menu, search for "calibrate display color," then open the matching result, and follow the on-screen instructions.

To manually open the ClearType Text Tuner, press Windows + S, search for "adjust ClearType text," then follow the on-screen instructions. On each of five screens, you"ll select the text samples that look best to you.

Photo Friday is a photography site. Think of the challenges involved in adjusting the brightness and contrast of a shot, and you get the reason you should calibrate your monitor. So, head to the link for their monitor calibration tool beneath the homepage, or hit the link above.

The site offers this simple one-page monitor calibration tool to adjust the brightness and contrast of your screen thanks to the gray scale tones. The idea is to tweak the monitor settings (or buttons) so that you can clearly distinguish the transition of tones from true black to true white. After calibration, the blacks should look black and without any hint of gray.

The instructions start off by telling you to dim the lights and hit F11 for viewing the gray scale chart in full-screen mode. Observe your monitor from your normal viewing distance.

The Lagom LCD Monitor Test Pages are a far more comprehensive set of tools than Photo Friday. The site includes a series of test patterns that start from checking contrast to checking for response times of your monitor. It is recommended to go through the tests in the order they are placed.

For a beginner, it might seem overwhelming. But, the test patterns come with helpful explanations. The developer also states that you can put the images on a USB drive and try them in the computer store when shopping for an LCD monitor. A 120 KB ZIP file download is included.

The Online Monitor Test website has a range of interactive tests to fix your screen colors. The menu appears when you move your mouse to the top. It starts off with a test that checks the brightness and contrast across the B/W tonal spectrum. It is similar to the test we covered on the Photo Friday website.

Next, the Color Range test checks if your monitor can smoothly produce color gradients. From the menu, you can pick different color charts. Look for “ghost images” or image trails in the Trailing test. Move the box across the screen and check if any trails are produced. The controls and options to change the color and shape of the box are placed at the bottom.

The Homogeneity test helps to pinpoint damaged pixels and faulty monitors with backlight bleeding. 1:1 Pixel mapping and testing for a blurring of Text are the last two tests on the lineup. While the former is not so much an issue with LCD computer monitors, the latter is worth a tryout if you feel that screen text is not crisp enough.

The author also provides a series of “Gamagic” test patterns you can use to calibrate your monitor. Fall back on your eyes and adjust the gamma setting with the monitor controls until all the squares match up with their backgrounds as closely as possible.

This single page screen calibration chart has few of the test images we have already covered in the earlier tools. Go through the color, gray scale, and gamma adjustments.

Windows 10 comes with the Windows Calibrate Display Color. You can access it from Start > Control Panel > Appearance and Personalization > Display. Or, simply search from the Cortana search box with a keyword like “calibrate.”

On the macOS Sierra, use the Display Calibrator Assistant. You can access it from Apple menu > System Preferences > Displays > Color > Calibrate. Or you can also use Spotlight.

Over time, the image quality on your computer monitor can start to look a little lackluster or even too bright. Before you consider upgrading your entire system or getting a new monitor, there might be a much simpler, quicker, and economical solution — calibrate your monitor.

You could take your monitor to a professional to have it done, but doing it yourself is relatively quick and hassle-free and will greatly improve image quality. Manufacturers keep pumping out displays with new technologies like 4K UHD resolution, high dynamic range (HDR), and curved monitors, providing a veritable feast for the eyes — but only if they are properly calibrated.

The assorted terms — gamma, white point, etc. — may seem a bit daunting at first glance, but each utility provides a relatively simple explanation of what they all mean. Realistically, you don’t need to know the ins and outs of the jargon to calibrate your monitor.

Step 2: Now that you are in the calibration tool, follow the on-screen instructions to choose your display’s gamma, brightness, contrast, and color balance settings.

Step 1: In MacOS, the Display Calibrator Assistant is located in the system preferences under the Displays tab, in the Color section. If you are having trouble finding it, try entering calibrate in Spotlight to scan through your computer’s various folders and files. The results should show an option to open the utility in the System Preferences panel.

Step 2: Your Mac’s step-by-step instructions will walk you through the calibration process once you have found and opened the software utility. Just follow the on-screen instructions to choose:

Color adjustments: White point is a given, but Apple will try to detect your display and offer a number of other color calibrations at this point … or it may skip the rest of the adjustment options entirely. Native Apple displays may be more likely to have fewer color calibrations at this point (because Apple already calibrated them).

W4zt Screen Color Test: This simple webpage provides you with several color gradients and grayscale color boxes you can use for quick comparisons, along with an easy gamma test you can run. It’s nice to have so many tests on one page, making this solution great for fast and dirty calibration so you can move on.

The Lagom LCD Monitor Test Pages: Handy for both online and offline use, the Lagom LCD Monitor Test Pages not only allow you to adjust various things such as contrast and response time, but also allow you to download the images as a 120KB zip file, so you can check any monitor in-store that you are thinking about purchasing.

Calibrize 2.0: If you want a great tool that goes a little more in-depth than native calibration options, we suggest downloading Calibrize 2.0. It’s an excellent free wizard that carefully walks you through well-explained steps to help you calibrate color, grayscale, gamma, and similar settings on your computer.

The best way to avoid this problem and ensure that you calibrate your monitor correctly is by purchasing a calibrating device. You’ll need to spend a decent amount of money for the best control and precision. Still, there are affordable alternatives to help you achieve consistent color across all of your monitors.

These devices are user-friendly, involving a simple three-step process of fastening the device to your screen, plugging it into a USB port, and opening the calibration software. When the software starts running, you just have to follow the setup procedure. It’s fairly intuitive, but if you have trouble, you can find tutorials online that will walk you through it.

To use multiple displays (some of which are touchscreens), you need to tell Xorg the mapping between the touch surface and the screen. This can be done using xinput to set the touchscreen"s coordinate transformation matrix.

This is a guide to do that, the old-fashioned way, in cases when xrandr does not know about your separate screens because they have been merged into one (e.g., when using TwinView). Everyone else, please go to Touchscreen to do it the easy way.

Tip: If your device contains both a stylus and a touch screen and more touch devices, then please pay attention to the name when determining the device.

Substitute your own touchscreen"s vendor ID, model ID, the xrandr output name, and the calibration matrix that you calculated above. This is based on the assumption that you are using the libinput driver for your touchscreen.

If, after following these instructions, multiple clicks occur in different places when you touch the screen, you will need to build the ABS, applying this patch before you build the package. (This patch fails on the current xorg source, but the bug is present on at least 1 system.)

Using the simulation profile as display profile will override the profile set under “Settings”. Whitepoint simulation does not apply here because color management will not be used and the display device is expected to be in the state described by the simulation profile. This may be accomplished in several ways, for example the display may be calibrated internally or externally, by a 3D LUT or device link profile. If this setting is enabled, a few other options will be available:

This depends on the chart that was measured. The explanation in the first paragraph sums it up pretty well: If you have calibrated and profiled your display, and want to check how well the profile fits a set of measurements (profile accuracy), or if you want to know if your display has drifted and needs to be re-calibrated/re-profiled, you select a chart containing RGB numbers for the verification. Note that directly after profiling, accuracy can be expected to be high if the profile characterizes the display well, which will usually be the case if the display behaviour is not very non-linear, in which case creating a LUT profile instead of a “Curves + matrix” one, or increasing the number of measured patches for LUT profiles, can help.

Note that both tests are “closed-loop” and will not tell you an “absolute” truth in terms of “color quality” or “color accuracy” as they may not show if your instrument is faulty/measures wrong (a profile created from repeatable wrong measurements will usually still verify well against other wrong measurements from the same instrument if they don"t fluctuate too much) or does not cope with your display well (which is especially true for colorimeters and wide-gamut screens, as such combinations need a correction in hardware or software to obtain accurate results), or if colors on your screen match an actual colored object next to it (like a print). It is perfectly possible to obtain good verification results but the actual visual performance being sub-par. It is always wise to combine such measurements with a test of the actual visual appearance via a “known good” reference, like a print or proof (although it should not be forgotten that those also have tolerances, and illumination also plays a big role when assessing visual results). Keep all that in mind when admiring (or pulling your hair out over) verification results :)

If you are having issues with your Touchscreen, this may include being unable to access items to the edge of the screen. For example, your screen may require re-calibration.

NOTE: If Tablet PC Settings is not seen, then make sure that your touchscreen USB cable is attached if using external display. Also check that any touchscreen drivers are installed, you can download these from the Dell Support site.

The touch screen may start to lose its sensitivity due to foreign particles (such as sticky notes) that are blocking the touch sensors. To remove these particles:

Use a clean, lint-free cloth to wipe the surface and sides of the touch screen to remove any dirt or fingerprints. You may spray mild, non-abrasive cleaner or water on the cloth if needed, but not on the screen.

If you do not have Cortana enabled, Then either click the Start button on screen or use Windows key on keyboard. Then click Settings icon (cog). Then type Tablet Mode in the settings search box and select Tablet Mode Settings.

Calibrating your touch screen is a cinch, but the method will vary depending on which operating system you are running. These instructions will work with any model of Toughbook that comes with a touch screen. In fact, these instructions should work with any touch screen laptop.

If you’re running Windows 7, Windows 8 or Windows 10, you should already have a touch screen calibration tool. To find it, open up the start menu and begin typing “calibrate.” An item should appear labeled

Calibrate…. If you have a dual touch screen, you’ll get a message asking if you’d like to calibrate the pen input or touch input. Select whichever one you want to calibrate.

A white screen will appear with thin lines around the perimeter, about a half inch in from the edge of the screen. Somewhere along these lines will be a darker black crosshair. Touch the center of the crosshair, either with your pen or your finger, depending on which input you are calibrating (if you have a resistive touch screen like the one on a Toughbook CF-31 or some CF-19 models, it’s a good idea to use a stylus, but you can use a finger if you want).

After you tap the crosshair, another will show up somewhere else along the edges of your screen. Tap that one as well and repeat the process until it asks you if you want to save the calibration data. If you’re happy with your tapping accuracy, click OK. Otherwise, click cancel and start the process over. If your touch screen has more than one type of input (as with a dual touch model), you can calibrate it using the same method.

The previous instructions assume your touch screen mode is set to Auto, and, unless you’ve gone into your laptop’s Basic Input/Output System (BIOS) and deliberately changed something, it probably is. If, however, you still can’t get your touch screen calibrated, your touch screen mode may be set to “Touchscreen Mode.”

If you are not sure and you want to check, you can get to the BIOS by pressing F2 as soon as the Panasonic logo appears when booting up your laptop. Once in the BIOS, look for a setting called Touchscreen Mode. It should be set to either[Touchscreen Mode]or [Auto]. If it"s set to Auto, you can either try the above instructions again or leave a comment below and we’ll do our best to help. If it"s set to Touchscreen Mode, you can either change it to Auto or leave it as Touchscreen Mode and use the following method.

To calibrate in this mode, you’ll be using the Fujitsu calibration utility, which comes with the Panasonic touch screen driver. If your touch screen is working at all, you should already have the Fujitsu calibration utility. Open the Start menu and start typing “calibration” in the search box. Under Programs, you should see an item called Touch Screen Calibration Utility. Click it to open the Fujitsu calibration utility.

Similarly to the Windows touch screen calibration tool, crosshairs will appear around the edges of the screen. The biggest difference here is that the crosshairs are red instead of black. Touch each one, working your way around the screen until the crosshair reaches its starting point. After you’re done, hit the enter key and begin dragging your stylus or finger around the screen to test the calibration. Once you’ve tested your calibration, press the enter key again to save the changes and exit.

Calibrating your touch screen on Linux may be a bit more complicated than it is on Windows, as every flavor of Linux is a little different. Some Linux distros already come with a touch screen calibration utility, but for our purposes we’ll assume that we need to install one. These instructions will also assume you are using Apt as your package manager (the default in many distros, including Debian, Ubuntu, and all their variants and derivatives). If you are using

Tap each crosshair that appears on the screen. Once you’re done, the terminal will spit out some more text. Select and copy the portion that starts with

Paste the data into the empty text file, hit Ctrl+X to exit and Ctrl+Y to save, then hit enter. Your touch screen is now calibrated and should stay that way even if you restart your computer.

Disappointed by your monitor’s image quality? You might be able to improve it through monitor calibration. Learning to calibrate your monitor will make the most of its potential, and while you can purchase expensive tools for this task, you can often achieve a noticeable improvement without them.

You don’t need to target these standards. In fact, precisely targeting a standard is impossible without a calibration tool. Still, you’ll want to be aware of these standards as you calibrate your monitor because they’ll impact how certain monitor settings work. Also, many monitors have settings meant to target them.

Nearly all monitors sold in the last decade have a backlit LCD display. This means they have a LCD panel with a light behind it. The light shines through the LCD to produce an image (otherwise, it’d look like the Gameboy Color).

To calibrate contrast, visit the Lagom LCD contrast test image. An ideal contrast setting will let you see all color bars from 1 to 32. This can be a real challenge for an LCD monitor, especially on the dark end of the image, so you may have to settle for a lack of visible difference in that area.

On the other hand, setting the contrast too high will cause colors at the high end of the spectrum to bleed into one. This problem is avoidable on a modern LCD monitor by turning down the contrast which, in most cases, is set to a high level by default.

You need a calibration tool to precisely adjust gamma, but you can make improvements using the Lagom LCD gamma test image. As its instructions say, you’ll want to sit back from your monitor (about five or six feet away) and look at the color bars, each of which is made up of several bands. You’ll see a point on each bar where the bands start to blend together. The gamma value indicated where this occurs is your monitor’s approximate gamma value.

Your monitor may include gamma settings in its on-screen control menu. Less expensive monitors will have a selection of vaguely labeled viewing modes, like “office” or “gaming,” with their own prebaked settings. You can flip through these while viewing the Lagom LCD gamma test image to see if they improve the gamma.

No test image can help you target a specific white point. You need a calibration tool for that. However, most monitors will have several color temperature settings that you can flip through in the monitor’s on-screen menu.

So, how do you dial in color temperature without a calibration tool? I find it’s best to view a blank white screen, such as a new image or document, and then flip through the available color temperature settings. This will help you settle on a setting that fits your preferences.

Even content creators may not need a calibration tool. Calibration is often considered a must for professionals, but the definition of professional is not what it used to be. Tens of thousands of self-employed creators make excellent content without ever touching a calibration tool. These creators don’t have to conform to any standard aside from what they think looks great. It’s true some creators have a reputation for remarkable image quality and slick editing, but most just use whatever they have at hand.

Monitor calibration is an important task for photographers. A properly calibrated monitor will accurately show you the colors in your images, so when you share or print them, you have done everything you can to ensure the final photo is seen as you intended.

As a result, many users don’t bother to calibrate their monitors correctly. Or, they might try, get lost in a world of conflicting advice and complex terminology, and give up. I have definitely been one of those people in the past.

However, if you want the images you are producing to be as accurate to life as possible, then color management is something you are going to have to get on top of. To help out, I’ve put together this guide that covers how to calibrate a monitor, as well as an explanation of some of the terminology involved.

I will preface this post with the statement that monitor calibration and color management is a complicated topic. If you do a search for how to calibrate your monitor online, you will unearth thousands of web pages and forum posts discussing the topic of monitor calibration.

Your monitor or screen likely has some controls that let you change how it looks. This will apply for any of your devices, whether it is your desktop computer monitor, laptop screen, smartphone device, tablet, or external monitor.

The controls will vary depending on the type of screen, but in general they will allow to you change things like the brightness of the screen, and perhaps other things like the saturation and contrast.

The controls on an external monitor will likely be similar to those you might find on a TV, and are usually accessed via a button. No doubt you are aware that you can change things like contrast, brightness and color on your TV, and this changes how the image looks. This is the same for a computer monitor, and to some extent, other device screens.

There are also other ways you can control how your screen looks. These settings are normally configured and controlled through the operating system on your device, which might be Windows, iOS, Android, or Linux. Adjusting these settings is known as color management. Basically, you are adjusting how different colors appear on your screen.

Well, the main reason is for consistency. Let’s think of a photo for a moment. If a monitor is correctly calibrated, when you look at the photo you took on the screen, it should match fairly closely to what the scene looked like when you took the photo.

Once you edit the photo, of course it will likely look different to the original, depending on the adjustments you make. However, when you come to share your image, either digitally or physically, you want to be sure that what other people see matches the image on your screen.

If you plan on printing your images, then having a correctly calibrated monitor is particularly important, so you know that the printed image will look as it does on your screen. It can be very disappointing to spend time editing an image and find out that the printed result doesn’t match what you see on screen.

If you are selling your photos, perhaps as a wedding photographer, landscape photographer or event photographer, having print images that match how they look on screen is critical. The person buying the shot will want what they buy to match your vision.

For sharing to the web, or other digital mediums, color management is still important, although perhaps not quite so much. The reason for this is that you can’t control other people’s screens. If your screen is set up correctly, but someone else has their saturation set to a high level for example, your image will appear more saturated to them.

Before diving into the details of how to calibrate your screen, I want to cover some terminology that you will encounter when it comes to display technology and color management.

RGB stands for Red Green Blue, and this indicates that every color displayed on a screen is made up of these three colors in varying intensities. It is what is known as an additive color model, because these three colors are added together to make the final color.

To define each color a screen can display, a number between 0 and 255 is assigned to each of these three channels. 0 means none of that color, 255 means all of that color. For example, red is denoted as RGB (255, 0 ,0). This means to show this color, the monitor must show 100% of the red light, and 0% of the green and blue light.

What this means in practice is that the same RGB values produce a different color in sRGB compared to Adobe RGB. So for example, RGB (227, 30, 16) refers to a different color in sRGB compared to Adobe RGB. This is why it is so important to know the color space, as it directly affects the final colors that are displayed on the monitor, as it is converting all these numbers into actual colors on the screen.

However, a better solution to either of the above options is to create your own ICC profile to match your monitor. You can do this either using software calibration tools, or by using a device known as a hardware colorimeter. More on this in the section below on how to calibrate your monitor.

OK, we’re onto the easier parts now. The majority of monitors and screens on the market have a brightness control, which allows you to change the intensity of the light coming from the display.

If you are trying to work somewhere where there is a lot of light, you will likely need to increase the screen brightness so you can see the screen properly. This is because in a well lit environment your eyes adjust to the ambient brightness, and make the screen seem dark. So you have to increase the brightness.

It is worth bearing in mind that the brightness of a screen does impact how colors appear. In addition, if you edit your photos on a bright screen, you might incorrectly adjust the image brightness. The result is that your printed images come out too dark.

When you adjust the brightness of a screen, it equally affects all the colors on the screen. This can result in black areas becoming grey and washed out, which is undesirable. Decreasing the brightness has the opposite effect – blacks become more black, but white starts to become grey.

When calibrating a monitor, you can choose a white point. This will allow you to choose what sort of white you want, from a warmer yellow white tone through to a cooler blue white tone. The white tone will vary depending on your surroundings. If you are working in an environment with cooler lighting, you will want a cooler white point, as otherwise your screen might appear too yellow to your eyes.

Conversely, if you have more warm lights in your working environment, you will want a warmer white point, as otherwise the screen may appear too blue to your eyes.

Ok, we’ve done all the terminology. Hopefully it all made sense or you at least have a general idea of some of the reasons why monitor calibration is important. Let’s now look at how to actually calibrate your screen.

If you are using a laptop or desktop with an external screen, you have two main options for calibrating it, which are to use the software that it comes with or to use a hardware device known as a colorimeter.

If you have a smartphone or tablet, most of these do not allow for complex color calibration, although they might allow you to adjust saturation and other features. My advice would be to properly calibrate your monitor first, and then adjust any settings on your smartphone you can to make images look similar.

If you have a Mac or Windows PC, then you will be able to use the built in software to calibrate your monitor. The process is similar for both platforms. Basically you launch the color management tool on each platform, and will be taken through a number screens where you can calibrate your monitor.

On Mac, go to System Preferences -> Displays, and then click the Color tab. This will show a list of profiles, and to the right will be an option to Calibrate. To start calibrating, choose this Calibrate option, which will launch the calibration tool.

On Windows, just type “Color Management” into the start menu, and choose the “Advanced” tab. Then, in the section titled “Display Calibration”, press “Calibrate Display”.

I will walk you through what this looks like on Windows with some screenshots to give you an idea of what this looks like. The process is very similar on an Apple device.

As you can see, when you go through the process, the program tells you what to look for, and you then make adjustments using either sliders in the app, or the on-screen controls your monitor offers you.

However, there are some serious downsides to calibrating your monitor this way. The major issue is that you are relying on your eyes to calibrate the colors on your monitor.

The new SpyderX is the first colorimeter from Datacolor that works using a lens, rather than a light sensor. This means it is can do the calibration much faster compared to previous models. The previous version, the Spyder 5, took around 5 minutes to measure and calibrate a display. The new model takes closer to 90 seconds.

This might not seem huge, but if you have a number of displays to calibrate, it is definitely a time saver. In addition, monitor calibration is a task that should be repeated at least once a month, as monitors tend to shift their colors over time. So if it takes less time, you are more likely to do it.

You have to confirm that you have warmed the monitor up for at least 30 minutes, that there is no light falling onto the screen, and that you have reset your display to the default settings.

Then, you will go through a number of settings specific to your setup. It will ask you questions about the type of display you have, and then give you the options to recalibrate a display, check your display accuracy, or do a full calibration.

If this is your first time, you will want to do a full calibration. It will show you the target settings, based on your screen, that it is aiming for in terms of brightness, gamma, and white point. You can manually adjust these options if you want, but for the first run I would advise leaving the default settings.

There is another feature that is quite neat, which is the room light setting. In an ideal world, we would be editing all our photos in a fairly low light environment. This means that we don’t need to crank up the display brightness. Setting a high display brightness means images looks brighter when editing than they might actually be, and is a common reason that prints look darker than the image on screen.

Of course, we don’t all happen to have a photo editing dungeon, and Datacolor has factored this in. The Spyder X has an ambient light sensor, so it can detect how much light there is in your environment. It can use this during calibration, and also to adjust the brightness of your screen on a daily basis as light levels change in your room.

Once you have everything set, the tool will place itself in the centre of the screen, and show you where to place the Spyder. A tip – the Spyder needs to be flat against the screen, not dangling. If you have an external monitor, you will likely need to tip it back a bit to get the Spyder to lie flat. A laptop screen is a lot easier to work with as it tilts easily.

When it is done, it changes the color profile your computer uses and lets you set a name for it. It also shows some example images you can use to see how the profiling turned out. At this point you will have the option to toggle a before and after version of your screen calibration, and use the test image provided to see the difference.

At this point in the calibration, the screen may appear to be more blue or more yellow than you are used to. This is not unusual – if you have been using a poorly calibrated monitor, your eyes will have adjusted to this as normal.

In summary, if you are looking to calibrate your monitor, a hardware tool like the Spyder X Pro is going to be the best option. You can definitely get results with a software calibration tool, but these are unlikely to be particularly accurate.

If you want your prints to match your screen, and to have color accurate images in general, I would recommend the Spyder X Pro as a fast and easy to use solution. It’s available direct from Spyder here, and on Amazon here.

Now you have a fully calibrated monitor. Your photos on screen should be accurate to how they will appear on print, and on other calibrated monitors. At this point you might be wondering the best way to share your images with other people so you can be sure they see them as they should be seen.

The two best options would be to send client actual proofs of the prints, printed out for review. Of course, this is going to incur a cost, which you might have to consider. Another option is to have them review the photos at your studio, or to bring your own color managed laptop with you to somewhere you can show them. This way you know they will see them on a properly color managed screen, so there are no surprises.

If the above options are not possible, then consider putting together some tips on the best viewing conditions for the images you send them digitally. Perhaps suggest they view them in a darker room, with their screen brightness turned down. You might also suggest if they have control over saturation, to reset this to a “natural” setting or similar if this is an option.

The easiest calibration setting is one that most people have probably already used. The "Backlight" setting changes the amount of light your monitor outputs, effectively making it brighter. Changing the backlight level on your monitor doesn"t alter the accuracy of your screen significantly, so feel free to set it to whatever looks good to you. It"s sometimes called "Brightness", which can be confusing. Generally, if there"s a single setting called brightness, it refers to the backlight. If there"s both a backlight and brightness setting, the backlight is the one you should be changing (as the brightness setting alters the gamma calibration, which we"ll look at later on).

The brightness and contrast settings change the way the screen displays tones at different brightness levels. These are easy options to adjust when calibrating your screen without a dedicated calibration tool, as most of the job can be done fairly accurately while simply displaying different gradient patterns.

Most graphics card software applications have a dynamic range setting that lets you toggle between limited and full RGB range. A full RGB range means that the image is displayed using all 255 values, with 0 being absolute black and 255 being absolute white. It"s the default range for sRGB and the recommended setting for most modern LCD monitors. The limited range (16 - 235) is mainly used for TVs as most movies and TV shows are mastered in the limited range. In short, you have to match the source and the display as forcing your full-range monitor to display a limited RGB range makes the image look washed out, and forcing a limited-range display like a TV to show a full RGB range crushes blacks. The pattern we use is for calibrating a full-range display.

Sharpness is one of the easiest settings to adjust, and generally, the default tends to be fairly accurate. Adjusting the sharpness changes the look of the edges of shapes that appear on-screen. Having it too low will give you a blurry image, while setting it too high will give the picture an odd look with strange-looking edges. It"ll also usually cause close, narrow lines to blend and produce a moiré effect.

The simplest way to calibrate this aspect if you aren"t pleased with the default is to set it at max, then lower it until no strange pattern forms between the lines and shapes of the test image.

The color temperature adjusts the temperature of the overall picture. A cooler temperature gives a blue tint, while a warmer temperature gives a yellow or orange tint. Think of it as the tone of the light outside at various times of the day. When the sun is shining bright at noon, the clouds and skies look almost pearl white without a distinct yellow. However, the light is yellow in the morning and evening as the sun rises and sets, and at night, white objects look blue when everything is lit by moonlight. We recommend a 6500k color temperature, which is the standard for most screen calibrations and is equivalent to midday light (also called Illuminant D65). It"s generally on the warmer side of most monitors" scales. Some people find it too yellow, so feel free to adjust it to your preference.

If you do calibrate your monitor using a tool, your calibration software will likely create a calibration profile that ends in .icm. This is an ICC profile, effectively a reference table that your computer"s programs can use to display content accurately on your screen. In general, Apple"s macOS is better at handling ICC profiles, whereas Windows and Windows applications tend to be quite inconsistent with how and when they"re used. Generally speaking, hardware calibration yields better results, but since most monitors don"t allow for full calibration using the OSD settings, ICC profiles are essential to getting the best possible image accuracy.

The overdrive setting adjusts the speed at which the monitor"s pixels switch from showing one thing to another. Usually, the default setting tends to be optimal, but you might prefer setting it higher or lower. A too strong overdrive setting will cause the pixels to overshoot, which creates a strange-looking inverted ghost following moving objects on-screen. A too low setting will create more motion blur, with longer trails following moving objects. You can learn more about overdrive in our motion blur article.

The refresh rate of your monitor refers to the frequency at which it updates what is shown on-screen every second. The standard refresh rate found on most monitors is 60Hz, but some screens, usually gaming-oriented, support upwards of 360Hz. You should almost always set it to as high as possible. You can learn more about refresh rates and our related tests in our refresh rate article.

Similar to modern mobile devices like smartphones and tablets, many monitors have a blue light filter that can help reduce eye strain. It"s often called "Low Blue Light" or "Reader Mode," and it essentially reduces the amount of blue light emitted by the screen, giving it an amber shade. It"s said to be less fatiguing on the eyes, especially at night. Most desktop operating systems have this feature built-in: "Night Mode" on Windows, "Night Shift" on macOS, and "Night Light" on Chrome OS. There are also third-party apps that can do the same. We recommend leaving this off when calibrating your monitor.

Unless you have the equipment to perform a more thorough calibration, calibrating a monitor by eye is largely a trial and error process, so it may take a few tries before you get the results that you"re looking for. Fortunately, most monitors have a reset feature to discard any changes and bring the settings back to their defaults if you end up with worse image quality. While it"s generally recommended for content creators to calibrate their displays once a month because accuracy can drift over time due to panel degradation, most people can probably get by for much longer in between each calibration.
