I’ve probably spent hours by now tweaking the picture, and I think I’ve found something that looks natural and works well for most uses.
First of all: set the picture style to standard.
- Colour: 50 (anything over 50 will blow out detail in highly saturated textures)
- Contrast: 60 (this setting actually controls the backlight intensity; turn it lower in dark conditions)
- Sharpness: 5
- Brightness: 60
- Colour enhancement: OFF (turning this on will blow out finer detail in saturated textures)
- Dynamic contrast: OFF (turning this on will cause the image contrast to shift noticeably during half a second after scene transitions, and I found it distracting)
- Video contrast: 100
- Ultra resolution: OFF (while making 1080p content look more crisp most of the time, it produces some artifacts and makes lower resolution content look jaggy)
- Noise reduction: OFF/MIN (doesn’t do much difference)
- MPEG artifact reduction: OFF/MIN (doesn’t do much difference)
- Perfect Natural Motion: MIN (a matter of preference if you want to make the content play more smooth, but settings higher than “Minimum” will produce noticeable artifacts, which I found distracting)
- Clear LCD: ON (doesn’t make much difference)
WARNING: Going into some (unrelated) menus in the settings will restore the changes you’ve made (I presume this is a bug), so be careful!
