99% DCI-P3 Sounds Impressive. But Does Your Work Actually Need It?

Only if your work ends up somewhere that uses that colour space. DCI-P3 is the colour standard of digital cinema and the basis of the Display P3 space used by Apple devices and much HDR video. If you edit video for those outputs, or want to see the full colour of modern phones and HDR content, high DCI-P3 coverage matters. If your work is web graphics, office documents or social media, it mostly targets sRGB, and accuracy within sRGB matters far more than a big P3 number. If you print, Adobe RGB coverage is usually the more relevant figure. A wide gamut can even make everyday sRGB content look worse if the monitor does not restrict it. A monitor such as the ASUS ProArt PA279CRV, which offers accurate sRGB, Adobe RGB and DCI-P3 presets, costs S$779 at SourceIT (listed 30 Oct 2026).

What are the main colour spaces for?

From ViewSonic's colour gamut explainer (May 2026), BenQ's colour gamut guide and ITU-R BT.2020.

What does "99% DCI-P3" actually measure?

Usually, coverage: the share of the DCI-P3 colour triangle that the monitor can reproduce, measured on a two-dimensional chart. It is not the same as accuracy. A monitor can cover 99% of DCI-P3 and still show colours inaccurately if it is not calibrated. Some specifications also quote figures above 100%, which usually means the monitor's gamut is larger than the standard in some directions, not that it is more accurate. RTINGS's tests add colour volume, which considers how much of the gamut a monitor keeps at different brightness levels, a better guide for HDR.

Coverage tells you which colours a monitor can show. Accuracy tells you whether it shows the right ones. You need both, in the right colour space.

Can a wide gamut be a problem?

Yes. When a wide-gamut monitor displays sRGB content without restricting it, reds, greens and skin tones look oversaturated. Display Ninja found the ProArt PA279CRV's Native mode does not clamp to sRGB, so the sRGB preset or colour-managed software is needed for accurate web content; KitGuru found a QD-OLED gaming monitor measured ΔE 4.88 against sRGB in its default mode, falling to about 1.2 in its sRGB mode. Windows 11 added Auto Color Management to map unmanaged apps into sRGB, but it depends on supported hardware and settings. See Why Your Photos Look Different on Every Screen.

So how much gamut does your work need?

What about bit depth?

A wide gamut spread across too few steps can show banding in gradients. BenQ explains that 8-bit gives 256 tones per channel, about 16.7 million colours, while 10-bit gives 1,024 per channel, about 1.07 billion. Many monitors use 8-bit plus frame-rate control (FRC) to approximate 10-bit, which BenQ calls adequate for most work. Display Ninja found the PA279CRV uses 8-bit + FRC; ASUS lists the high-end PA32UCXR as true 10-bit.

Reading specifications sensibly

1. Check which colour space a percentage refers to, and whether it is coverage or relative size.
2. Look for a measured ΔE in a relevant mode, ideally from an independent review.
3. Confirm the monitor has accurate presets for each space you use.
4. For HDR, look at sustained brightness, contrast and certification, not gamut alone.

Frequently asked questions

What is DCI-P3 used for? It was developed for digital cinema and is widely used for video, HDR content and Apple devices. It is about 25% wider than sRGB.

Do I need DCI-P3 for photo editing? For print, Adobe RGB coverage is usually more relevant. For screen output, accurate sRGB matters most; DCI-P3 helps if you target modern phones and HDR displays.

Is a wider colour gamut always better? No. Without an sRGB mode or colour management, a wide-gamut monitor oversaturates ordinary sRGB content.

What is the difference between gamut coverage and accuracy? Coverage is how much of a colour space a monitor can show; accuracy, measured as ΔE, is how close the displayed colours are to the intended ones.

Does 8-bit + FRC matter? For most work, no. BenQ describes 8-bit + FRC as adequate for most uses, with true 10-bit preferred for high-end retouching and HDR grading.
