I purchased a U2412M a few months back and I have had an issue that has been occurring intermittently. What happens is half the screen will go entirely black and the other half begins flickering and is unreadable. Obviously when this issue occurs the monitor is unusable. It used to only last about 5-10 minutes or so and would go away. Today however it happened and has not gone away. I tried updating the video drivers and tried multiple cables to connect the monitor to the computer and it still did not resolve the issue. If anyone has any suggestions it would be much appreciated.
