2021-01-28, 13:05 PM

On L13 Gen 2 screen is flickers on some grayscale colors and on some blue gradients. Here is sample image, which causes it (look at it on internal screen). Is it ok or is it a defect?

Changing contrast just makes different colors flicker. The color in the post flickers on 17 and 18

Got L13 Gen2 too.

Most probably it is caused by screen used inside this product which has only 6bits per color channel.

They are somehow simulating 8bit color channels, but once it decides that it is time to save power - then you can see those artefacts like flickering.

 

What age do we live in where market makers like Lenovo ThinkPad are not thinkpads anymore and they ship this kind of products to customers?

Why Lenovo did not mention on PSREF portal that screen is in reality 6bits per color channel and 8bits is simulated? This is uncorrect against customers.
