Works great when it's on......
After more than 700 hours of use, I'd like to add my opinion on this screen.
All too often I have problems with vertical streaks appearing on the screen.
This video is a good illustration: https://www.youtube.com/watch?v=80LqlG0cq8Y
A restart of the screen is enough to make them go away but sometimes they leave a mark that takes several minutes to go away.
Apart from that, there's no problem, the slab is pretty, bright and vivid, and the 1440p is pleasant - it's hard to go back to 1080p.
