The display in our review device comes from the BOE supplier and is of very high quality. Subjectively, you can rejoice in a vivid and sharp image, which is minimally grainy. This is only noticeable on white areas. However, this is really just nitpicking; the same goes for the light screen bleeding on the two side edges. PWM is not used.

Lenovo advertises the display with a brightness of 500 nits, which we're able to thoroughly confirm with our measurement. As a matter of fact, all measuring points surpass this value, and it's around 520 nits on average. The high brightness gives the black value a hard time, resulting in it being slightly elevated at 0.37. But the contrast ratio is still very good at 1435:1. What we don't like, however, is the brightness gradation, because even at one level below the maximum, the value drops to only ~220 nits, and at 80% it is only 139 nits.

Compared to the Full HD display of the T590 and to the optional 4K display of the old ThinkPad P52s, the new matte 4K display is clearly superior in all areas. The 10-bit display supports DolbyVision HDR in addition, and apps like Netflix, YouTube or Amazon Prime make the videos available in the corresponding quality. The system chooses the maximum brightness automatically in order to intensify the HDR effect. Although videos look great, the effect can't be compared to a proper HDR TV due to the limited brightness.
