Hi All, I have a Hanns G 24.6in HD monitor (HH251), and I love it. It's about three months old, and is used primarily for my XboX 360. Within the last two or three weeks, when I first turn it on, the screen will get a little darker after about two minutes, and then I'll lose picture altogether. I can remedy this either by turning the monitor off and then on again (and the problem won't happen again once the monitor is warmed up), or I can unplug the HDMI cable and reinsert it (again, solving the problem until the next time the monitor hasn't been used for awhile). I have no idea what might be causing this, and whether it's cause for alarm or is just a minor inconvenience. Any thoughts/help would be much appreciated!
