So nobody bothered to think "Hmm, maybe he simply has Brightness turned up too high.", but instead jumped directly to the brand war? "Oh, it's a Samsung! That must be the problem!".
Jesus.
Okay, tadtv. You have 1 post so I have no idea your skill level. First suspect is of course Brightness (that horribly named parameter that actually controls black level). Put on one of your credit screens again and turn your Brightness down. There should be a point where turning it down doesn't change the color of black anymore, that being the point where you went too far.
Bring Brightness back up to the point where clicking it up one notch shows a noticeable shift to a lighter shade of black, then drop down one notch again.
How does it look now? If it is still too light, then yeah, you're unhappy with the panel's black level. If it's a hell of a lot better, then you were just unhappy with the display's out of the box software settings.
Next step. Go flip through your DVDs and find one that is THX mastered and therefore has the THX Optimizer on it. It's free, as you probably already have it in your home.
Run that and follow it's on screen directions. Yes, there are better calibration discs, which everyone here is about to tell you, but this will get you 90% of the way there in 5 minutes.
