![]() ![]() We could not determine PWM flickering (even with the ePrivacy filter enabled), but the response times are quite slow and you can also see ghosting during operation, e.g. ![]() Realistically, it only brings the desired effect at low brightness levels, which can be problematic especially on the go. You can then increase the brightness again, but the effect of the privacy filter is then practically gone. Lenovo tricks a bit here by reducing the brightness to ~160 cd/m² by default when the filter is enabled. The difference between enabled and disabled privacy filter (Fn + D) is actually not very big either. ![]() The viewing angles are also much worse than those of regular IPS displays. Even with small deviations, contrast and brightness visibly decrease and it almost seems as if a gray haze covers the picture. Due to the ePrivacy filter, there is only a very small sweet spot when looking centrally at the display (even when ePrivacy is disabled). However, the subjective picture impression in practice is much worse than these rates suggest. At the same time, the black value is very low (0.24), which leads to a very good contrast ratio of 2400:1. Lenovo states a brightness of 500 nits, which we can confirm according to our analysis (CalMAN & X-Rite i1 Pro 2) and the average brightness is even a bit more than 540 cd/m². The optional ePrivacy screen in our test device offers a resolution of 1,920 x 1,200 pixels (16:10) on the 14-inch diagonal. ![]()
