DIFFERENCE BETWEEN SINGLE AND DUAL LAMP LCD ? HELP....

[greekisland]

CAN ANYONE TELL ME THE DIFFERENCE BETWEEN THE SCREENS ON THE AR SERIES,NAMELY ON THE AR51J,AND AR51SU-IS THERE REALLY LOWER QUALITY ON A SINGLE LAMP LCD ?
MANY THANKS AND HAPPY HOLIDAYS IN ADVANCE.

The main difference is in the screen resolution.

The AR51SU has a screen resolution of 1920 X 1200 and can display full HD output at 1080p.

The AR51J has a screen resolution of 1440 X 900 and cannot display HD output.

Double lamp technology just gives a brighter image.

Thanks Blencogo.I knew about the resolutions and HD output,but I've read reviews on notebookcheck.com and found a very poor rating on the screen of the ar51j,whereas the ar51su got stellar rating for screen.My current Vaio,FE31M,has dual lamp screen.I'm very satisfied with it,I just want to upgrade to a 17inch,but without massive quality loss.I would really like to buy the AR51M which is the perfect "in between" for me but I can't find it here in Greece.Seems all outlets are stocking AR51J & AR51SU only.
In general I haven't heard many good things about the AR51J,which is my target price range.Is it really such a compromise model ?
Thanks again for the reply....
