Hi, I'm currently borrowing one of these TVs and have been looking everywhere for the best settings but had no luck, I then decided to do it myself and my best settings are as follows:
Starting with the picture mode as standard,
Backlight - 100
Contrast - 100
Brightness - 47
**Sharpness - 60**
**Colour - 60**
**Tint - 0**
The settings that I have put a star nex to were settings that I couldn't change i.e. they were greyed out. The reason for this is that my 360 won't outpout sound through the HDMI port (even after the 'fix')the piece of rubbish, so I am using the VGA port for it, which I think looks better anyway. Then we have got the advanced settings, again the ones that have a star next to them, I couldn't change.
Advanced Settings:
Colour Temperature - Medium
**Fresh Contrast - Off**
**Fresh Colour - Off**
**Noise Reduction - Off**
Gamma - Medium
**Black Level - High**
**Eye Care - Off**
**Film Mode - Off**
And that is it, as I said earlier though, theese settings are from an XBOX 360 elite through VGA/RGB but the results of this are very good. If these settings still don't look correct then, if possible, reply with the item(s) thet you are using with the set and I will see if I can fiddle around and get some results with that set up. Hope this helps you.
