i recently have got my lcd screen replaced (of my alienware m14x r2) because it started showing a thin vertical blue line on the screen.

but after the change the new screen is missing a key feature of the original screen, the auto brightness control. earlier when the desktop background changed from dark to lighter images or video, the brightness used to dim accordingly. but in this new screen it does not happen. it adjusted well on the eyes and i miss that.

now i want to ask if i should go for another replacement or do the replacement screens simply don't have that feature ??

moreover the service guy who opened the case cracked the plastic screen cover at one place and now it does not fit well :(

plz help

thanks ...
