For Mac users, getting accurate colors on external monitors ranks high when choosing a display. That’s why it pays to choose a monitor designed with macOS in mind. Mac-optimized displays help prevent color mismatches and other visual inconsistencies, which is especially important for color-critical work like photography, design, and animation.
Let’s look at how to get accurate colors on external monitors for Mac, both when buying a display and setting it up, plus you can browse monitors designed for Mac.
Why Your External Monitor Doesn’t Match Your MacBook Display
While resolution used to be a reason for basic visual discrepancies, modern Mac and Windows PC all use the main standard screen sizes. You’ll easily get 1920 x 1080 full HD or 3840 x 2160 ultra HD on either platform.
No, the biggest issues are panel bit depth, color gamut or space, pixel density, and HDR. If you opt for a generic PC monitor that doesn’t take these into account, it doesn’t matter how much you tinker with settings on Mac or monitor, you won’t get the image quality you should enjoy.
What to Look for in an External Monitor for Accurate Colors
Check for the following before you even consider tweaking display settings. These need to guide your buying choice if you want to get accurate colors from an external Mac monitor.
Panel bit depth and color precision
You want a 10-bit monitor to get the most accurate Mac colors on an external display, or at least an 8-bit frame rate control (FRC) monitor. The latter does a decent job of emulating 10-bit color, while native 10-bit panels offer smoother gradients and better HDR performance. Display P3 (or DCI-P3, which is the non-Mac equivalent) support depends on color gamut coverage, not bit depth alone.
Color gamut and Display P3 support
All modern Macs, desktops and laptops, use the Display P3 color gamut, or color space. This color space is a massive increase over standard RGB, or sRGB. In fact, Display P3 has 25% more color coverage than sRGB. Hook up your Mac to a regular sRGB 8-bit monitor, and you miss out on a quarter of Apple’s intended color specs. Settings can’t compensate for missing color gamut coverage. You need a monitor with at least 98% DCI-P3 coverage.
Pixel density
Mac colors and visuals in general look best on high pixel density monitors. Aim for at least 160 pixels per inch, or PPI. However, to really match Apple standards, 218 PPI works best, like with the flagship ViewSonic VP2788-5K. That external Mac monitor offers 99% Display P3 on a pristine 5K (5120 x 2880) panel.
HDR
You need to ensure the external monitor complies with at least HDR10. Beyond HDR metadata, your monitor should have good brightness output. Look for at least DisplayHDR400 certification. Because Mac content leans toward HDR more than does Windows PC, good HDR helps avoid dull, washed out visuals.
How to Set Up My External Mac Monitor for Accurate Colors?
In the monitor OSD or on-screen display, make sure the following are selected:
- Color profile: use Display P3 or DCI-P3. As we mentioned before, these must be supported for the right color space performance.
- HDR mode: optional, but if your external Mac monitor supports HDR, use a preset such as DisplayHDR400 where available.
Check macOS Display and Color Settings
On the Mac side, go into System Settings and then Displays and make sure your Mac matches the settings on your external display.
- Check that the same color space is selected, so if your monitor uses DCI-P3, ensure your Mac is on Display P3
- If you want to use HDR, verify that macOS HDR settings correlate with your monitor’s HDR mode. External monitors use standards like DisplayHDR, not Apple’s Display XDR preset.
- Resolution is surprisingly a common source of problems. Clearly, your Mac and external monitor must match for best results. Don’t use 1920 x 1080 on a 4K monitor, or 4K on a 5K external display. We recommend using the highest resolution available on your monitor, for obvious reasons.
What’s the Best Way to Calibrate an External Mac Monitor?
In the Color Profile macOS settings, you’ll find the Display Calibrator Assistant by clicking “customize” on any given color profile. This is a software tool that walks you through basic steps to make sure you have baseline color accuracy.
It’s OK in a hurry, but hardware calibration gets far superior results. And even better, you want a monitor that arrives factory-calibrated with an individual results report.
Self-Calibration and Color Accuracy
Over time, even a well-calibrated monitor can drift as the panel ages. That’s where self-calibration becomes useful. On Mac-optimized ColorPro monitors like the VP2788-5K, self-calibration via the monitor’s on-screen menu, or hardware calibration using ViewSonic’s Colorbration+ software and a supported sensor, helps maintain consistent Display P3 performance over time.
Then, real image pros should consider using ViewSonic’s Colorbration+ calibration software together with a supported hardware calibration sensor. ColorPro monitors support popular devices from Calibrite and X-Rite, making it easy to run regular re-calibration sessions and keep your Mac and external monitor properly aligned over time.
Final Thoughts
To make sure you get accurate colors from your external monitor for Mac often proves trickier than the plug and play nature of working with a Windows PC display.
Every kind of Mac has very demanding and high standards for color and image settings. You can’t just get a basic PC monitor and hope for the best, as that’ll cause issues. From color gamut to pixel density and HDR, there’s a checklist of essential specs to keep in mind. That’s a lot simpler if you opt for an external monitor optimized for Mac, laptop or desktop. Taking the time to check those specs upfront helps avoid unnecessary compromises later.
Frequently Asked Questions for How to Get Accurate Colors on External Monitors for Mac
Why do colors look different on my external monitor compared to my Mac’s built-in display? MacBook displays (especially Retina, Liquid Retina XDR, and P3 displays) are factory-calibrated and support wide color (Display P3). Many external monitors use sRGB by default or are not calibrated, which can cause visible differences in color, brightness, and contrast.
Do I need a special monitor for color accuracy on Mac? Yes, and very much so. For best results, insist on monitors that have Display P3 or DCI-P3, factory hardware calibration with individual test results, and 10-bit color (or at least 8-bit FRC).
What color profile should I use for my external monitor on macOS? You should use Display P3, so make sure your monitor supports this.
Don’t use Adobe RGB or sRGB unless no other option is available, as you’ll get compromised color performance.
How do I change the color profile for an external Mac monitor? – Go to System Settings (or System Preferences)
– Select Displays
– Choose your external monitor
– Open Color Profile
– Select Display P3 or enable HDR where supported
Should I purchase a factory calibrated external monitor for my Mac? Yes, as that ensures you get started right out of the box and minimize visual discrepancy hassles.
Should I regularly calibrate my external monitor? Yes. Calibration ensures consistent and accurate colors, especially for photo and video editing, graphic design, and photography.
Is the macOS built-in Display Calibrator sufficient? It’s helpful for basic calibration, but depends on your visual judgment. For professional or color-critical work, a hardware calibrator from Calibrite or X-Rite provides far more accurate results.
Should I consider using sRGB? No, if your monitor offers Display P3 or DCI-P3, use those. They’re around 125% the color gamut of sRGB.
Does the cable or connection type affect color accuracy? Yes. For best results use premium DisplayPort or USB-C/Thunderbolt cables. DisplayPort and USB-C/Thunderbolt are preferred, but HDMI works well if it supports the monitor’s full resolution, refresh rate, and color depth. Low quality or incompatible cables hurt visual fidelity in a big way.
Why do colors look correct in some apps but not others? Some applications manage colors independently of macOS. Professional apps like Adobe Photoshop, Lightroom, and Final Cut Pro are color-managed, while others may ignore color profiles and lead to inconsistent results.
