Why do moving lines become fuzzy on my monitor?
- by CodeInChaos
I recently got a new notebook. With moving images there are some graphical issues, and I'd like to know what causes them. None of my earlier monitors exhibited similar issues.
Moving high contrast lines become jagged, similar to interleaved videos. When moving a horizontal line vertically those artifacts are colored, when moving a vertical line horizontally they aren't colored. The effect isn't observable in static images. And when moving faster the zone in which it occurs becomes wider.
The effect is very visible if I move a window around on the borders of the window and wherever high contrast lines appear. But it appears when watching videos too.
The vertical line in that image moves to the right, the horizontal line upwards.
The effect is most likely related to the fact that each real pixel consists of different sub-pixels for the different color channels.
But how are these causing the observed effect? Is the change at which the different colors change to the destination brightness different?
The optical impression is that every second pixel in a chess board like arrangement is adapting slower than it's neighbors. But that doesn't make much sense.
