First thing I thought of was the same thing as jammur21. Too bright. Seriously, all monitors come with the brightness settings jacked up to 100. It does not need to be that high. It is that high because with a casual view (such as the display models sitting in Staples or Best Buys) it looks great with the brightness jacked up really high. However, when you are working and staring at the monitor it will cause fatigue. If you haven't already, try lowering your brightness to 50%.
