Hardware Forum - LCD screens question - Page 1

Having only recently gone over to LCD from CRT, I was wondering...
While most of the time the quality is great (Samsung C650 as you're asking) I often notice differences in picture quality between channels (compared to CRT where they seem quite consistant) and even difference between scenes in the same prog (eg: last weeks Spooks. Exteriors fine, inside the boat the pic is very flat and uncontrasty like it's trying to compensate for the darkness. And The Libertine on Film 4 was really washed out and 'flat'). Surely I shouldn't have to adjust picture settings when I change channel? Or is the TV just 'too good' and showing up disparities in the signals?!
Also, Dark Knight on Blu-Ray.... looks great but skin tones vary a lot. Sometimes Gary Olman's face is really bright orange then he nips outside and looks pale and poorly!
And this supposed wide viewing angle thing... mmmmm not sure and it's certainly not 178 degrees. I find you have to be quite bang on centre (widthwise and heightwise to get the best picture. And when turning it on the picture seems to need a couple of minutes to get to the proper brightness (bit dark at first)
So in a nutshell. Is this all normal?  If not, are there settings I should be setting (or unsetting)?
I obviously did all the usual set up business when I first got it to get the 'best' picture.
