How accurate is Redmi 15’s large 144Hz display?

The Redmi 15’s 6.9-inch display is one of its most talked-about features, boasting a 144Hz refresh rate and Full HD+ resolution. While it delivers a smooth and immersive experience, colour accuracy tests reveal that it doesn’t reach the precision of higher-end panels. Its performance is solid for daily use but falls short in professional-level accuracy.

Test results indicate that the Redmi 15’s LCD panel achieves around 700 nits of typical brightness and peaks near 850 nits under High Brightness Mode. This makes it more than bright enough for indoor use and adequate under moderate sunlight. However, the colour output leans slightly towards cooler tones, and saturation is less vibrant than on AMOLED displays in similar price brackets.

When measured for accuracy, the panel covers roughly the sRGB gamut with limited DCI-P3 coverage. This means colours appear reasonably natural but not ultra-rich or cinematic. Whites and blues tend to dominate slightly, while reds and skin tones can look a touch subdued. For casual viewing and social media content, this is rarely an issue, but creative users may notice it.

Contrast ratio testing shows another typical LCD trade-off. Blacks appear greyish in darker scenes, and the contrast lacks the depth seen on AMOLED-equipped rivals. Watching dark-themed content like films or games still feels smooth thanks to the 144Hz refresh, but finer details in shadows aren’t as distinct.

The panel’s viewing angles are stable, though there is a minor drop in brightness when tilted off-axis. Xiaomi’s adaptive refresh rate feature helps maintain smooth visuals without excessive battery drain, but the refresh rate doesn’t influence colour calibration directly. The overall look stays consistent, just not perfectly tuned.

Touch response is excellent, supported by a high touch-sampling rate that gives the phone a snappy feel during navigation and gaming. While not directly tied to colour accuracy, it contributes to a more premium experience overall.

Outdoor visibility is decent but not exceptional. The display maintains legibility under sunlight, though reflections can slightly wash out the colours. Users who often use their phones outdoors may need to increase brightness manually for clarity.

When compared with AMOLED-based rivals from Realme and Samsung, the Redmi 15’s display holds its own in brightness and refresh smoothness but can’t match their richer contrast or deeper blacks. Still, for its price range, the overall colour balance and clarity remain competitive.

In real-world terms, most UK users will find the Redmi 15’s display perfectly fine for videos, browsing, and gaming. It’s only when you look for true-to-life colour accuracy—such as photo editing or content creation—that its mid-range nature shows.

In conclusion, the Redmi 15’s display performs impressively in size, brightness, and smoothness, but its colour accuracy is average. It’s a well-balanced screen for everyday entertainment and productivity, just not the benchmark for precise or professional colour work.
