You don't mention which model you actually have , But there is something that Samsung is trying to keep under the radar when it comes to their panels in LCD's. Samsung are actually using three (that i know of) manufacturers of panels in their LCD cabinets. The best by far is "S" type panel made by Samsung themselves (these were the ones distributed to reviewer/review sites etc), and off course look great.
The Second i know of is made by AU Optronics and is known as the "A" series and displays less accurate colours than the "S" series.
The Third that is appearing is "C" series and is made by CMO ,from what i can tell this panel is getting mixed reception some have no complaints (or may of not seen the quality of an "S" panel to compare) and others can't stop complaining about it.I have compared it to the "S" personally, i found a noticeable backlight bleed in the "C" in dark screen conditions and actually seeing what appeared to be an H on it's side.
There's no way to tell what panel your getting without oppening the box before buying,once you do have it in front of you the serial number sticker on the back of the unit will have either "S" , "A" or "C" , a few are appearing without any series letter.There is a service OSD menu that can be accesed by bringing brightness and contrast down to 0 and then holding source button for 5 seconds until the menu appears. This will give you the series also.
I'm also hearing of that being left blank in the Service OSD menu also , in which case the only way to find out if you have a real Samsung panel is to get out a Phillips screwdriver.
Good Luck and hope you get an "S"
