The B610 models have a Wide Color Enhancer 2 technology, while the B630 models have a Wide Color Enchancer 3 technology. So in essence, it's not the identical panel, but the settings for one might work pretty closely with the other.
You could try the settings for the other as a starting point, and that may help you get to where you want to go with tuning your picture.
Hope that helps.
Can anyone tell me if these two Samsung models are the same. Looking at their specs, they look pretty much identical with the exception of internet connectivity so I wondered if I could use the 630 settings for my 610?
