I have a Toshiba L50D-B83110 laptop (AMD A8 APU with AMD Radeon R5 M230 graphics) running Windows 8.1.
I have the same issue as the OP of this question: Green flickering pixels that move with black images, namely,
Occasionally, on my LCD screen, pixels that should be black flicker rapidly and constantly between black and green, about 4 flickers a second. The crazy part is, unlike dead/stuck pixels, they are relative to content on the screen and move with it. For example, when I'm watching movies or playing games, the green dots move along with the objects/characters in the game/movie.
To check whether the GPU's busted, I plugged in a monitor to discover that the monitor works fine. I hope this means there's probably nothing wrong with my GPU. Now I'm wondering, Is it just a loose connection or a damaged LCD?
The drivers are up to date.
What could be causing this?
Help would be appreciated.
