Hello again everyone! :)

As you may, or may not know, (some of) the new 2011 range of Philips TVs have separate Day and Night settings. This is of course very important, as the lighting conditions in the room can have a big impact on the picture you see!

So I thought, as the 2010 PFL9705/9955 series do not have this yet, why not make a simple manual, how to convert your regular Night settings (for artificial light or dark conditions) into proper Daylight viewing settings?...

First thing I noticed when figuring this out, is that the Local Dimming functionality (which is extremely valuable at night), is in fact not necessary during the day. The black level during the day is already nearly perfect without any dimming, and the contrast is a lot stronger with the Local Dimming "Dynamic Backlight" feature turned off. Shadow detail, which can be rather weak under brighter lighting conditions, is also improved a lot this way.

So you turn "Dynamic Backlight" off during the day, but then you will notice how much effect this setting has on almost every aspect of the picture. How can you possibly get the same picture quality without "Dynamic Backlight" during the Day, as you have with it at Night!?... ;) Well, this is how...


But first remember that the following settings are not absolute settings. They are differential settings, compared to your own favorite settings while having "Dynamic Backlight" at "Best Picture":

Contrast: (-) 7
Brightness: (-) 1
Color: (+) 1

Perfect Contrast: (+) 1
Dynamic Backlight: Off
Gamma: (-) 1


You will notice now that, for most pictures, like when watching the news, a soccer match, or a movie scene outdoors, there is hardly any difference between this new Daylight setting and your old favorite Night setting. But when the scene gets darker, and the Local Dimming function would have come into action otherwise, the differences get bigger of course: the picture stays brighter now, shadow detail is improved and the contrast is a lot stronger!

As I said, this is a manual to turn your favorite Night settings into proper Day settings, while retaining the best possible picture quality. These Day settings can also be used at night when watching one of those "difficult" movies that show a lot of dimming artifacts, like haloing around bright objects, or the subtitle dimming problem. But in that case, of course the black level is not as strong and the picture is a bit brighter. Shadow detail stays pretty much the same though and so does the picture in general... without the artifacts this time!... :rolleyes:


I hope you will find this manual useful. Now you can enjoy your great set even more! :cool:

Have fun with it,

Freddy

Why don't you simply enable the light sensor?

Have you ever tried the light sensor!?... ;) It is way too sensitive, making the picture either too bright during the day (with still poor shadow detail), or really really dark at night (causing the picture to become rather "flat"). The result is nowhere near as good as when using separate settings for Day and Night viewing conditions.
