Dell has replaced the screen. No flicker any more but it is still quite difficult to set the resolutions (when setting the "desired" ones, ie 1600x1900 & 1920x1080) some parts of the screen remain black, and among this black parts some let the cursor visible (but only the cursor, i.e. dragging a window there leave the area black), and some don't even let the cursor appear.
