Color accuracy
How closely a display's output matches the intended reference colors, measured as Delta-E. Lower is better; ΔE under 2 is generally indistinguishable from reference for trained eyes.
Color accuracy quantifies the gap between the color a display shows and the color the source signal specifies. The metric is Delta-E (CIE 2000 is the modern standard).
- ΔE < 1 — calibration-grade. Unnoticeable to anyone.
- ΔE < 2 — professional. Unnoticeable to most.
- ΔE 2–4 — acceptable for general work.
- ΔE > 4 — visible to trained eyes.
A monitor can have wide gamut and still be inaccurate. A monitor can have narrow gamut and be very accurate within it. Both matter, but accuracy is the harder spec to fake. Professional-grade monitors ship with factory calibration reports.
How to use Color accuracy in a real comparison
How closely a display's output matches the intended reference colors, measured as Delta-E. Lower is better; ΔE under 2 is generally indistinguishable from reference for trained eyes. In practice, this is most useful as one part of a decision rather than a standalone quality badge. Compare it alongside the workload, room, ecosystem, budget, and ownership constraints that apply to you; the strongest published figure is not automatically the best outcome for every buyer.
What to check next
Open a product page and check the stated value, configuration, price, and related trade-offs before treating this term as decisive. It is especially relevant in .
Avoid the one-number trap
Manufacturers can describe the same capability under different conditions. Compare like-for-like variants, check the unit and test condition where available, and use a head-to-head page to see whether a measurable difference is material for your own use.
