Also, I'm led to believe the software is backwards for the c450's color space settings. I've been doing research, and "auto" seems to be the usual correct colorspace for HDTVs because it reaches all posible color gamuts and automatically adjusts to the source. "Native" is thought to expand the color space regardless of source, and is understood to be the improper setting in almost all circumstances.
The b450 thread parallels this for the most part- auto being the correct setting and native being incorrect. EE_engineer confirmed this with some techy talk on "auto" vs. "native", and that he couldn't tell any visual difference in color between the two settings. However, one poster mentions he heard from a Samsung tech that all quality issues/testing is done on "native" settings for their plasmas. Another poster mentioned that the "native" color setting allowed him to get more accurate tint/hue settings with a calibration DVD that he couldn't get with "auto". So I did some experimenting:
On my Samsung LCD, when alternating between "auto" and "native"
-native makes reds/blues fluorescent and overly vibrant
On my c450 plasma
-auto makes reds/blues fluorescent and vibrant (it does what "native" does on the LCD)
I feel its kind of strange that Samsung possibly has these settings backwards, and that for these c450s (at least the models with the same software I have) should be on "native" for color space. I don't understand why the color space settings would do the opposite for their LCD vs. their plasmas. I also noticed that "native" is the default color space in "Standard" mode which was the default mode the TV was in after initial setup. Movie was defaulted in "auto". I'm curious to the effect these have with Blu-Ray sources....I'll have to check my other LCD to see if its opposite as well.....anyone tried tinkering with auto/native ?
