I have a HP LCD color display monitor - product 20555SH249 Product # P8740AA
Model # HSTND 2171-A1. Recently in the left hand upper corner a box has appeared saying Luminance
has Contrast in red and Brightness (blue) another line. Please help me get rid of this as it is very annoying.
Can't click on it as can't get my cursor on it. If I leave the computer for a while it will go away but as soon as
I return and type anything it is back.
Thank you
Pauline Fenner
