Nokia X7 Review
Nokia X7 is available at promotional prices on Gearbest in several variants: black 6GB+128GB, midnight blue 4GB+64GB and silver 4GB+64GB.

Display

Nokia X7 is equipped with a 6.18-inch IPS PureDisplay with an 18.7:9 aspect ratio and an FHD+ resolution (1080 x 2246). By default, the display has a notch but from the Display settings you can change it to a standard view. The unit is fully laminated. Full lamination increases the sensitivity of the displays and allows them to be even thinner. The display is covered with a 2.5D curved NEG glass and takes up 82.32% of the whole front surface of the handset. Below you will find our measurements of the white and black luminance, static contrast ratio and colour temperature of the display. The measurements are taken in two different ways. The Single Frame ones show the white and black luminance of a screen that shows 50% white and 50% black. These measurements should provide more realistic data about the actual contrast. The Separate Frames measurements show the white and black luminance of a fully white and fully black screen.

A single frame, 50% white / 50% black

Brightness White luminance Black luminance Contrast Color temperature
100 % 522.561 cd/m2 0.383 cd/m2 1364 : 1 8334 K
0 % 7.725 cd/m2 0.006 cd/m2 1288 8048 K

Two separate black and white frames

Brightness White luminance Black luminance Contrast Color temperature
100 % 540.888 cd/m2 0.399 cd/m2 1356 : 1 8307 K
0 % 8.040 cd/m2 0.006 cd/m2 1340 7974 K
When we measured the white and black luminance values on a fully white and a fully black display, we got slightly higher white luminance values at all brightness levels compared to the single frame measurements. The maximum brightness in this occasion measures 541 cd/m2. The black values are either slightly higher or equal to the ones received from the single frame measurements. The static contrast ratio in both cases gravitates around 1350:1. The temperature of the white point from the two separate frames measurement is almost equal to the one from the single frame measurement. The content on the display is clearly visible outdoors under direct sunlight.

The CIE diagram clearly shows a colour space coverage that's significantly wider than 100% of the SRGB one. Nokia specifies it as 96% of the NTSC colour space reference and adds that the model supports the standard DCI-P3 wide colour gamut and HDR10 video playback The display panel has a traditional vertical striped RGB subpixel arrangement.
