My EM 170 TFT monitor has developed two white lines at the bottom of the screen.The first one, 1mm thick appeared some two months ago, and the second, hair line size, only appeared last week.
What causes them and how can I remove them?
Some sony monitors (i think they're called trinitron or something) have two little dark lines running horizontally across the screen to support the screen's matrix.
seeing as yours are appearing from nowhere i would suggest you try a different monitor, check the cables to the monitor and finally try a different graphics card.
