The Lenovo ThinkPad T470p is offered with two different panels. According to the official manufacturer specs, there are the options to equip the device with a Full HD panel or with a WQHD panel. For the Full HD display, the brightness is specified as 250 cd/m², whereas the WQHD display is supposed to reach 300 cd/m². Our test unit is equipped with the WQHD panel. At a resolution of 2560x1440 pixels, the 14-inch display size results in a pixel density of 210 ppi. Even though Lenovo advertises the panel with a brightness of 300 cd/m², our measurements show that the average brightness of our test unit is only 267 cd/m². In comparison, the panel of the HP EliteBook 840 G4 is considerably brighter at 317 cd/m².

In the brightness distribution, the Lenovo ThinkPad T470p only achieves a rather mediocre result of 87%, and the contrast ratio of 1084:1 has improved slightly in comparison to the predecessor. The WQHD panel struggles with slight backlight-bleeding, which becomes mainly noticeable in dark image content. There should not be any adverse effect during everyday usage. It is very good that the dimming function operates without PWM.
