Go to display properties by rt click on empty spot on desktop, left click on properties, then click on settings, then advanced
you will see all options for display
brightness, contrast, color, depth etc
do a little at a time
you can try cl open gl or color tab
these are all in 'advanced' settings in display properties

And if pressing the Fn and arrow keys to ajust brightness and contrast don't work why is that ?
Is it b ecause I have a 2nd mouse plugged in to my Dell, and large keyboard ?
Shouldn't think so.
Any one have any other ideas why ?
