Yeah it was only really noticeable when moving between the browser and my terminal (dark theme). I think they cheaped out a bit on the panel used in it, which is a shame as otherwise it's a cracking little laptop.
Is yours an IPS or TN screen? From what I've read the fleet buyers will do anything to save a few dollars a unit so Lenovo offers TN as a base model for that market.
Yep, there are two version, but mine is IPS, clearly visible from the viewing angle and the bios ID, yet the burnin is there. But again, the used laptop cost me around 1/7th of a Macbook Pro :)
