Display Quality, Tests

The Mate 9 packs a 5.9-inch 1920 10 1080 IPS LCD with a pixel density of 373 PPI. I'm a little disappointed this phone has used a 1080p display over 1440p at this size, equally I feel 1440p would deliver noticeably crisper text and imagery in some situations, likewise as being meliorate suited to mobile virtual reality. 1080p is still decent enough in 2022 and this display looks great, it'southward just not the all-time hardware available.

Alongside excellent viewing angles, the Mate 9's brandish produces over 600 nits of brightness at top, which is a fantastic result that places this display amidst the best LCDs. Due to this high level of brightness, y'all'll have little trouble viewing the Mate 9 in strong sunlight. The display's contrast ratio is likewise respectable; it's non at the level of AMOLEDs, but it does assist make colors pop.

Color accuracy out of the box isn't terrible, but information technology'south non fantastic. Default color temperature is very cold, giving the display a blue tint in all situations. This leads to poor grayscale accuracy and gamma. Saturation and general accuracy are disappointing for a phone that doesn't exceed the sRGB spectrum (I recorded 98.6% sRGB coverage); in other words, the brandish isn't oversaturated, it'southward just inaccurate in general.

The only option Huawei provides for calibrating the display is a color temperature circumvolve that allows you to tint the brandish towards any colour in the spectrum. At that place are also "warm" and "cold" options. For best results, y'all should manually elevate the dot all the style to the edge of the circle, approximately in the orange zone. This doesn't fully correct the display'southward color temperature, but it does make information technology closer to the platonic 6504K.

With the display 'calibrated' in this way, color accuracy improves to a minor extent. The biggest gains are seen in grayscale performance, just even in this expanse the display is still not properly accurate. It'southward a shame Huawei doesn't include an sRGB calibrated option hither, though the display looks pretty expert in full general for casual users.
