Hi,
Got a PD5000 yesterday, but wanted a pedestal (moving house soon, will probably wall mount in new place.
RS offered the 'Chameleon' model, but I had a nightmare figuring it out, I too was trying to use the rather obvious bolt holes at the bottom. Eventually realised the significance of the 4 screws in the back and worked it out, however the stand was pants and not suitable for the screen - basically just not stong enough and induced a terrifying wobble.
Swapped for the 'Partington' model which is excellent in construction, but does not have holes for the PD5000 - it looks like the PM400 and possibly PD3000 have holes with the same horizontal spacing, but a different vertical separation. I just popped four more holes in the backing plate and mounted it according to the instructions and I think it looks the bizz.
From the picture above I am sure the PD3000 wall mount will fir the 5000.
As for the display I had grave concerns about picture qual last night, and had a major panic that I had bought a lemon. Ater screwing around with all the settings, I eventually found that the default setting with just a touch less red look superb with my Tosh SD510 (component cables, NTSC prog scan enabled).
I was very pleased with the RGB SCART picture from the Sky box. A few of the channels show horrible artifacts, but I think these are more Skys fault than the box.
I still have a few niggles about the black level, it dark images still seem a touch grey, but I found that using a small lamp to light the wall behind the screen works wonders, and I have never used any other plasma in my own living room, so I can't really say how well it stacks up against the competition.
Must go and watch the mandatory Toy Story 2 plasma workout, but will post a few pics if I can jump start my old camera.
