I've had this Dell monitor for probably around 4-5 years and recently (from last month or so) it would flicker in a wierd way, and sometimes it lowers the brightness but eventually comes back to full brightness. Let me try to explain what my monitor looks like when it flickers... think of a puddle of water, stick your finger in the middle and pull it out... you see a cone shaped after effect from ur finger, and a rippling effect for the rest of the water. Its sort of like that. So, is my monitor dying? Is this its way of telling me to let it rest in peace?
