I have these problems, suddenly, after 10 months of perfect work, with no changes in my setup, the monitor started having it's 75% of the screen surface covered with flickering black lines. What's going on? I tried to answer in this thread, but I didn't find any "post reply" button. I will try to make the test failure, but what if it doesn't work? Can I ask for a new monitor after 10 months use? I was finishing a video project, and I didn't expect this issue with a good monitor as this, that's why I spent money on it!
Thanks for your support.
