Some LCD panels suffer from artifacts induced by a checkerboard or grid pattern that alternates every pixel.
This thread is about either or both of (photos/videos below):
* Static color changes on the grid area.
* Horizontal streaking all the way from the grid to the edges of the screen.
The amount of color distortion in the grid and streaks depends on how much "grid pattern" is present in each pixel row.
This thread is not about flicker on the grid while it's moved or while stationary, though it is possible the root cause is related (voltage inversion between pixels, see more details on Techmind and Lagom).
Following are lists of monitors/panels that are reported to exhibit, or not, these artifacts. The lists include desktop monitors, laptop monitors, and TVs.

Hey everyone. I'm getting strange visual bugs on a Sony W705B TV even when all image processing/enhancement features are disabled. Can anyone with a 2014 Sony model check if it happens for them as well?
Here's one manifestation. I'm getting this shown:
While the actual image is this:
1920x1080 test image. Click and view at 100% size for testing.
The above shot was taken with the latest firmware version, in "Game-Original" picture mode, all image processing disabled. It happens to a varying degree in other modes as well, depending on the settings.
Videos of the problem as it changes dynamically:
