I got a brand new Dell U2312HM about a week ago and it has been having this problem where the screen will flicker black for a second then revert to normal. it will do this in a group of like 3-4 and then it will stay normal for a few minutes before flickering again. This problem is usually more prevalent when i first turn on the monitor and then if i have been using the computer for an hour or two the problem will disappear. I've tried searching around the site for information regarding this and i couldn't find anything, so i decided to ask here before opening up a support ticket.
