Factors in Choosing the Best Monitor for Photo Editing
Selecting the right monitor for photo editing involves careful consideration of several key features:
Color Gamut Coverage
This refers to the range of colors a monitor can display. Professional-grade monitors typically offer wide color gamuts, exceeding the sRGB standard. Look for monitors that support Adobe RGB or DCI-P3 color spaces. The BenQ SW321C, for example, boasts 100% coverage of Rec. 709 and sRGB, and 95% of DCI-P3 – a significant advantage for accurate color reproduction. The Eizo ColorEdge CG319X pushes this further with 98% DCI-P3 coverage, demonstrating the range of options available.
Resolution
Higher resolution translates to sharper details and finer gradations in color, allowing for more precise editing. 4K (3840 x 2160) is becoming increasingly common in professional monitors, representing the optimal choice for meticulous work. However, QHD (2560 x 1440) remains a viable option balancing image quality and cost. The Dell U2723QE, priced around $699, offers a 4K resolution, making it a cost-effective choice.
Panel Technology
IPS (In-Plane Switching) panels are widely preferred for their superior color accuracy and wide viewing angles. These panels typically offer better color uniformity compared to other technologies. The majority of monitors listed in our reference data—including the BenQ SW321C, LG 32UL950-W, and Dell U2723QE—utilize IPS LED technology.
Color Depth
A higher color depth (measured in bits) allows for a smoother gradation of colours, reducing banding and improving overall image quality. 10-bit displays, capable of displaying over one billion colors, are commonly found in professional monitors; this significantly contributes to accurate colour reproduction. This feature is present in the BenQ SW321C and Eizo ColorEdge CG319X.
Calibration Options
Professional monitors often feature built-in calibration sensors or support external colorimeters. Calibration ensures that the monitor's color output remains consistent and accurate over time, mitigating gradual color shifts. The Eizo ColorEdge CG319X, for instance, features a built-in sensor.
Connectivity
Sufficient connectivity is necessary for seamless integration with other devices. Essential ports should include HDMI, DisplayPort, and preferably USB-C for convenient single-cable connectivity and power delivery, as seen in the BenQ SW272U and BenQ DesignVue PD3205U models.
Color Accuracy: Technical Aspects and Calibration
The technical aspects of color accuracy are complex; however, a grasp of the following concepts helps understand the capabilities of a monitor:
Delta E: This metric quantifies the difference between a color's intended values and the color displayed on the screen. A Delta E value of less than 2 is generally considered undetectable to the human eye, meaning perfect accuracy for professional-grade work. The BenQ SW272U boasts a Delta E value of ≤1.5, showcasing exceptional accuracy.
Color Calibration: Calibration involves adjusting a monitor's settings to ensure consistent color production over time. External colorimeters or built-in sensors help precisely measure and adjust a monitor's color output.
Monitor Picture Quality Tests: Color Accuracy
Several methods are used to test monitor picture quality, with color accuracy being essential in photo editing. These often involve using dedicated colorimeters and advanced software, comparing the monitor's output to the expected color values. The reported Delta E values (as found in the BenQ SW272U product specifications) are a core indicator of a monitor's accuracy. Higher Delta E values suggest inaccuracies.
Steps to Achieving Accurate Colors
Calibrating your monitor is crucial to maintain color accuracy. Here’s a step-by-step guide:

- Regular Calibration: Repeat steps 3 and 4 every few months or as needed to compensate for aging and environmental changes.
The Role of sRGB in Photography
sRGB (Standard Red Green Blue) is a color space widely used for web content and general-purpose displays. While not as wide as Adobe RGB or DCI-P3, sRGB's importance stems from its ubiquity. Web browsers interpret images in the sRGB color space, so images intended for the web must be ensured to maintain accurate colors within this space. Whilst photographers may often work in wider color gamuts, converting images to sRGB before posting them on websites is a crucial step.
Gaming Monitors with Color Accuracy for Photo/Video Editing
The advancements in gaming monitor technology have significantly improved color accuracy in some models. This opens up the possibility of using such monitors also for photo and video editing. However, to leverage these monitors for editing efficiently, look for key features like high color gamut coverage (at least 95% of DCI-P3) and high resolutions (4K is ideal). Specific models from the background content such as the LG 32GS95UE-B, Dell Alienware AW3225QF, and ASUS ROG Swift OLED PG32UCDM are examples of high-performance gaming monitors that also stand out in colour accuracy, but they come at a premium price. These models can compete with professional models, offering good features and performance. However, buyers must balance cost and features; high refresh rates, while desirable for gaming, are less critical for most photo editing workflows.
How Do Professional Photographers Ensure Color Accuracy?
Professional photographers employ several strategies to ensure consistency and accuracy in their workflow:

FAQ
What is the difference between Adobe RGB and DCI-P3 color spaces? Should a photographer prioritize one over the other?
Adobe RGB and DCI-P3 are both wider color gamuts than sRGB, offering a broader range of colors for image reproduction. Adobe RGB, historically used in professional photography and printing, tends to include a wider range of vivid greens and blues, often favored by photographers. DCI-P3, originally designed for digital cinema purposes, was later adopted by other media. Currently, it offers a good balance between wide color gamut and the color space supported by a growing proportion of display devices and digital content. Therefore, many professional photographers might find better general compatibility with DCI-P3. The “best” choice rests upon individual preferences and the intended output medium. If printing is central, Adobe RGB might be preferred, if the target is mainly screen displays or digital cinema, DCI P3 holds a stronger proposition.
How often should I calibrate my monitor, and what factors influence the calibration frequency?
There's no single definitive answer to how often monitor calibration should be done. This depends on factors like:
- The monitor's age and technology: Older monitors are more susceptible to drifts over time than modern ones.
- Environmental conditions: Variations in ambient light, temperature, and humidity affects.
- Usage intensity: Frequent use might accelerate color shifts.
Many professionals calibrate monthly. However, some might calibrate every few weeks or even several months depending on their workflow. Regular checks, visually comparing your monitor to known color references, helps to determine if calibration is needed sooner. Keep records of calibration activities and any issues encountered to understand your workflow’s nuances.
How do I know if my current monitor is accurate enough for professional photography?
A3: Determining the accuracy of your current monitor requires several steps. Firstly, check the manufacturer’s specification regarding colour gamut coverage (sRGB percentage, Adobe RGB percentage, DCI-P3 percentage etc). Monitors marketed as "photo-editing" or "professional" typically have color gamut information readily available. However, this information is a starting point. Many websites and utilities can help you test your monitor. Many software utilities provide Delta E testing, allowing you to compare the perceived colors to the actual color values, often comparing against the sRGB color standards. Using a colorimeter tool (like Datacolor Spyders or X-Rite) provides vastly more precise measurements and reports, which are invaluable for professionals. Remember to always calibrate your monitor before any testing. This ensures that the test results reflect the accuracy of the monitor’s output rather than systematic inaccuracies caused by aging or misadjusted settings.
