My friend used to have this monitor which i eventually down that past 4 years i inherited which is a Proview 770M. The problem is the best i come up with is that the monitor now seems to give too much contrast adn not enough brightness all the dark areas that ened to be lighter aren't and are too dark....now is there a way i can pop off the cover and fiddle w/ soemthign that fix's it? ive been on various websites but come up w/ not a lot of luck....any help would be great....
