Hi everyone, I did a search but haven't found any help yet. I purchased a 32" HDTV LCD-LED (Insignia NS-32E570A11) for use with my work computer. Looks great!! Except for one annoying thing that I cannot figure out...

...Whenever I close out of my browser (IE) or close a dialog box, the screen immediately darkens/dims. And if I reopen a box or the browser the brightness come right back. Any thought?

It's a 120hz display.....don't know if this is the reason or not.
