I just replaced the lcd screen on my Dell Inspiron 6000. The screen works alright, but it seems a little too bright and the color is slightly off. When I tried to adjust the brightness in Bios, I noticed that brightness / dimness were reversed. When I tried to make the screen brighter, it got dimmer. When I tried to make it dimmer it got brighter. Is there some simple problem to explain this? Did I install the screen incorrectly?
