A Complete Guide to HP Monitor Color Calibration

Today’s monitors have made dramatic improvements in color accuracy. Displays that only a decade ago would not only cost thousands of dollars but also take up your entire desktop space can now be found for just a couple hundred dollars and can easily fit into your workspace.
Looking to learn more about adjusting or calibrating colors on your display, or if you even need to? Read on for a guide to HP monitor color calibration.

The perception of color accuracy

For those working in the visual medium, whether that’s photographers, designers, professional creators, or casual creators, having accurate colors on your display is becoming increasingly important.
While many intuitively know that their smartphones feature color accuracy, you may not realize that you can calibrate or profile your computer display to make it more color-accurate.
When LCDs began to replace the CRT screens in monitors a number of years ago, the earlier generations weren’t as dynamic or distinctive. For instance, black showed as gray rather than being true black. Graphic designers and other visual technologists became accustomed to having to calibrate these lower-quality early-generation LCDs almost daily. As a result, a mindset of not being able to “trust” one’s monitor (color-wise) evolved from those expectations.

The importance of color grading

Color grading is the process of applying tools to enhance how colors appear – using attributes like saturation, contrast, detail, white point, and more – within still and moving images as well as videos. This is especially critical on displays to ensure that the colors and grade are accurate and appear consistently similar across different devices.
If you’re comparing one product image or one video commercial to another on different monitors, it’s important that they match. It’s one of the reasons that the Society of Motion Picture and Television Engineers (SMPTE) and the International Tele-production Union (ITU) have established worldwide standards on color.
A monitor that is properly calibrated ensures color and color grading accuracy regardless of the device, while the opposite is true: color grading on an uncalibrated monitor can produce a false grade that shows up differently when viewed on another screen.

Factory calibration

Factory calibration can be defined as performing a large number of measurements (60-plus measurements) of levels of different colors at different values on a display in the factory. Those measurements are then used to characterize the response of the display.
Without calibration, computer displays can be inaccurate. For one thing, they may weigh grayscale incorrectly, especially toward the lower range. This can result in a loss of shadow detail.

The benefits of monitor calibration

Monitor calibration allows the ability to smooth out all of those inconsistencies, creating correction (also called “lookup”) tables that are then stored on the display. With factory calibration, you won’t have to worry about how to calibrate monitors or the need to run color accuracy tests.
Factory calibration used to be performed only on very expensive, customized, boutique monitors. As the cost of technology has come down, though, that has changed. Most manufacturers, including HP, now offer a range of affordable display choices among their factory-calibrated premium monitors to match customer expectations. For instance, HP OMEN displays and HP Z Displays are factory-calibrated and have been for several generations.

Using monitor color profiles for non-factory-calibrated displays

Unlike premium monitors, most mainstream and entry-level monitors typically are not factory calibrated. In lieu of calibration, one approach is to use off-the-shelf (OTS) software or hardware to profile that display.
Profiling is the term for taking measurements and then creating and storing similar lookup tables as those in factory-calibrated displays. But instead you store these tables on your computer so that the host graphics processing unit (GPU) or graphics card can compensate on the output to the monitor.

Limitations to profiling

While profiling can produce similar results to calibration, there are limitations to what you can do compared to a full calibration. Typically, profiling allows you to correct the grayscale, along with the white point or the color of light. It cannot correct the color gamut, however. In addition, hot desking is not possible because you can’t guarantee that you‘ll get the same monitor from day to day.

Recalibration

Some of the higher-end creator displays, above the premium level, are set up for user recalibration. This counteracts the effect of aging on displays, which gradually dim over time, impacting the brightness.

Monitor profiling tools/software

If you want to profile your non-calibrated display, here are two of the more popular monitor calibration software and color calibration tools available.

X-Rite ColorMunki Smile

X-Rite is a pioneer in calibration technology, offering a family of color management solutions for some of the highest levels of color accuracy in the industry. The X-Rite ColorMunki Smile is an easy-to-use, affordably priced, and compact colorimeter calibration tool with a streamlined interface that’s ideal for beginners or casual users.

X-Rite i1Display Pro

For those looking for more professional support, the X-Rite i1Display Pro provides a number of customization options and software features with color precision, speed, and controls for high levels of on-screen color accuracy to fit virtually any workflow.

Calibration and color needs by user group

Monitors with 27-inch diagonals are now considered the “sweet spot” for most user requirements. Though, the ideal monitor size and what they’re looking for in those monitors varies by specific needs.

1. Gamers

Computer games are becoming more photorealistic and animation is increasing in quality. Accordingly, gamers, especially competitive players of triple-A (AAA games), are looking for monitors that provide cinematic quality and more realism with accurate colors.

2. Professional creators

Professional creators include photographers, designers, graphic artists, compositors, colorists, animators, and others working in the visual arts and sciences who have discerning eyes. Color criticality and accuracy are very important to them. This particular user group was among the first to drive the development of the world's first calibrated monitors. Professional creators want to recalibrate their displays approximately every 1,000 to 2,500 hours of use, which equates roughly every 3 to 6 months.

3. Casual creators

Casual creators are those who may have similar occupations and skill sets to professional creators, but they usually are those working exclusively from home, including contractors, freelancers, and even hobbyists. Because of the expectations of their client base, they too are becoming more attuned to the necessities of accurate color within their displays. Their expectations are that digital files and other non-printed output, such as streaming, need to match as precisely as possible.

Factory-calibrated HP monitors

HP offers a number of monitors that ship calibrated from the factory. Let’s take a look at a few of them.
