Clear deviations are found in all measured fields. Particularly the grayscale is poor

i see......

The TFT screen has a diagonal of 4-inches and a resolution of 480x854 pixels. That corresponds to a pixel density of a decent 245 ppi. In times of Full HD screens, this may seem a bit coarse, but it is more than sufficient for this screen size.

The screen's average brightness is 422 cd/m² and thus on a good level. The illumination of 82%could be a bit more balanced but this is not noticed in practice on a smaller screen like in the Xperia M. The Xperia L's brightness of 383 cd/m² is even a bit lower and the Acer Liquid (347 cd/m², 88%) and Nokia Lumia 520 (287 cd/m², 92%) are darker. However, particularly the Lumia's IPS screen excels with an excellent illumination.

Distribution of brightness

The black value of our review sample is quite high with 0.67 cd/m² and prevents a contrastbeyond 633:1. Black does not look really saturated but rather more like dark gray. However, the category contenders also range within this area. HTC's Desire 500 even manages the lowest rate in this comparison field with 0.8 cd/m².

The screen assessment does not improve this impression. Clear deviations are found in all measured fields. Particularly the grayscale is poor. Not only is the DeltaE of 12.4 much too high but we also very clearly noticed the bluish cast typical for low-quality TFTs. In particular, the small Nokiaproves that an entry-level smartphone can achieve a very good color reproduction in this exercise. It can even compete with many premium devices with a dE of 2.2.

The bright screen should actually be well-suitable for outdoor use, particularly since the contrast is quite decent. The Xperia M is pleasant to use in the shade. However, the screen becomes virtually illegible in direct sunlight. We would not have presumed this to such an extent in view of the measured rates.
