Got the tv installed now (came on the 1st as promised), and had 48 hours to play around with the settings for my own personal preference, and here are my thoughts:
Ambilight:
Pretty impressed with the feature so far, on watching SD content, HD film (from the 360) and gaming as well. Response time of colour changes is pretty accurate, as it features Ambilight Spectra 2, and with the set around 15cm (6 inches) from the wall, the light gives a good subtle colour spread without being too "in your face".
NetTV:
Had a bit of a play around with this new feature (present on the 8000 and 9000 series), and although services on there are limited at the moment (i'm in the UK), compared to the likes of Germany (region can be changed in the settings), it does have potential to be a worthy feature.
Youtube works brilliantly (I have an 18Mbps ADSL2+ connection), and the weather channel (run by Meteogroup) is set to the Netherlands as default, although you can search for weather by city (using the remote's keypad), the only limiting feature of the Internet browser is it's inability to show Flash and Javascript (Philips could add this at a later stage in a firmware upgrade).
The internet radio station channel, provided by tunin.fm works pretty well with genres sorted by category and a varied selection to choose from. Audio quality is good, although I have yet to connect the tv's audio out to my home cinema system to really examine this.
Picture quality:
SD:
With this being a full 1080p set, you would expect sources such as my Sky satellite reciever (connected via RGB SCART), to look really poor (as it did do with my old Sammy 32" LCD), but i've been pleasantly suprised. I've left the picture settings pretty much standard for the Sky box (settings are customised per connected device, if added via the Home menu), except for the light sensor which I have set to "off". The set does a really good job of smoothing out MPEG artifacts, although these are not completely irradicated with small text. Overall results from the Sky box are satisfactory for everday viewing (but will be improved once all five major channels switch to 24hr HD).
I have yet to test the tv's handling of DVB-T (Freeview to most people) as my old aerial is naff and I'm in the process of fitting a decent one (the set supports DVB-T2 / MPEG-4 for when/if Freeview goes HD).
HD:
This is where the tv comes into its own. Only one HD source connected at the moment, my Xbox 360. It was first connected via Component and set at 1080p although I did notice a little noise on certain edges and slight ghosting on some text, although this disappeared once I connected the 360 via HDMI, resolution to 1920 x 1080 and the reference levels to expanded. The 360's settings are set to 1080p and all the tv's extra picture processing has been turned off as follows:
Contrast: 75
Brightness: 46
Colour: 55
Sharpness: 5 (default)
Tint: Normal
Pixel Plus settings all set to off.
Here are some screenshots (may look slightly poor due to my camera being on my phone):
I also have Windows 7 Media Centre running on the 360 from my pc, with a DVB-S card installed, and able to watch BBCHD, Luxe TV HD and itvHD via the registry hack, the picture quality from all three channels looks superb.
Overall verdict:
Pretty impressed with the tv so far
, contemplating investing in a Blu-Ray player, possibly the Philips BDP7300 to complement the tv, then I can see how it handles true 24p.
I'll post some more feedback in about a weeks time.
