My husband bought a Dell Precision M6400 and a docking station to replace our old desktop computer. When the laptop is in the docking station and we are using our old monitor there is so much glare that I get eye strain and a headache very quickly. Also the print seems very indistinct at times and hard for me to read. My husband says he doesn't notice it. (!?!)We've tried changing resolutions, refresh rates, settings on the monitor. NOthing seems to help. What can we do?
