Akurát podsvietenie by mohlo mať trošku väčší jas:link
...ale nie je to nič hrozné. 230cd/m^2 ....Hlavné, že raster displeja je takmer dokonalý:link
Človek pred sebou neuvidí sito popretkávané obrazom, ale čistý obraz.
Tkisto PWM nebolo zistené:
Screen Flickering / PWM (Pulse-Width Modulation)
ℹTo dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected
In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9729 (minimum: 5 - maximum: 151500) Hz was measured.
Although the screen in Lenovo's ThinkPad T460 provides the user with a lot of elbow room in front of the display and remains superior to every TN panel, it is one of the weaker IPS panels. This is particularly noticeable in the relatively (!) early as well as visible brightness and contrast losses in horizontally shifted viewing angles. Distorted colors are only seen in unrealistic extreme positions as can be seen in the corner pictures of our viewing angle collage.
