Display: 5.v-inch 1080p LCD

The HTC One X9 comes with a 5.5-inch Super LCD with a resolution of 1920 x 1080, equating to a pixel density of 401 PPI. Like most 1080p smartphones I've used, the sharpness and clarity of this brandish is great. 1080p is at present the standard resolution for mid-range smartphones, then the I X9 doesn't really have an advantage over its competitors here, though that'southward not an issue because some flagships even so opt for the less power-intensive 1080p displays over 1440p.

Aside from the resolution, there's not a whole lot to like almost the One X9's brandish. At 415 nits, peak brightness falls below the ideal 500 nits mark for a smartphone, and this is particularly disappointing considering this telephone uses an LCD. Dissimilarity and blackness levels are both average for an LCD, while viewing angles are beneath boilerplate.

The worst aspect of this brandish is colour operation. Sometimes I forgive poor color performance if the brandish uses a wider-than-sRGB gamut, every bit this merely increases pinnacle-finish saturation, just this is not the instance with the I X9's display. This brandish's gamut actually sits below total sRGB, with 91.5% coverage, so the issues with accurateness are not from a basic increase in saturation.

Instead the bug prevarication with terrible mid-tone performance. Blueish, green and yellowish mid-tones are oversaturated significantly, which leads to colors being crushed towards the loftier end and loss of particular as well every bit color balance. When you expect at the 1 X9's display, something appears to be 'off' from first glance, and the explanation for this is poor accurateness through the mid-range. On top of that, the brandish tin't reach full dark-green or blue saturation levels.

Past default, the display has a common cold colour temperature similar well-nigh smartphones these days. This can be corrected through a slider in the One X9's software: adjusting it 3 notches to the warm finish pulled back the color temperature to around the 6600K mark. Unfortunately, this slider does petty to address the rest of the display'southward color inaccuracies, and at that place is no other fashion to pull the brandish in line with sRGB standards.

It's disappointing hither that HTC couldn't bring the same qualities from the HTC ten'south LCD, or even last year's HTC One M9, down to the cost point of the Ane X9. What we're left with is an inaccurate display that gets trounced by the cheaper Motorola Moto G4 Plus, which packs an LCD of the same size and resolution.
