Just closing this out to say that the fix for this issue ended up being physical replacement of the LCD screen. After swapping out the screen I haven't seen the issue recur.
I've started experiencing a problem with my m17 R4. I noticed a few black lines along the bottom of the screen, which extend about half way across the screen, before starting to fade out. I've attached some photos that show this behavior. Important details: At this point, although I'm able to temporarily get rid of the lines by reinstalling the graphics drivers, my concern is that this indicates a hardware issue that will only get worse. Below are several photos that show the lines along the bottom of the screen. [IMAGE]Beyond the center of the screen, the lines fade out completely. They don't go all the way to the right edge of the screen.[IMAGE]Closer to the center of the screen, the lines begin to fade out.[IMAGE]The lines are very sharp and noticeable along the bottom of the screen. [IMAGE]The lines are visible even in the pre-boot test.
