Hi there,

First let me start by saying: this is a great forum, and I already learned alot!

Now my "problem":

I recently bought a Samsung UE55C6700 (wich presumably is the same as the american UN55c6500) and tried to "calibrate" a THX optimizer i found on the pixar "cars" dvd. I know these are biased towards the cars movie, but i reconned it is a nice first step for an amateur like me. And cars is a nice reference movie i guess.

I disabled all the fancy (and useless ) processing like edge enhancement etc, but when setting the contrast while looking at the 4 (?) shades of white test pattern, no matter what contrast setting, I can always distinguish all the shades. i tried to see if the backlight setting had anything to do with it, but that doesnt seem so.

Did I forget to disable an image processing feature?
Am I doing something wrong?

I'm using "Movie" and "warm" as base settings.

Hope somebody can help me out here, thanks in advance!

The Netherlands, Europe.

You did nothing wrong. The contrast is set correctly to not permit people to wreck the image if they wanted to.

Since you can't get it to clip ... then move onto discoloration of the bars next ...

Finally ... consider eye fatigue factors ... aka ... if it hurts your eyes, the backlight is too high.
