Just got this and set it up. All i can say is wow. I thought 56" would be too large for about 4m away, but its ok. I've owned the D45 but had too many problems so decided to go for this model. Its the same as the D45 in terms of pic quality, inputs etc. but i find this better with pure white scenes (like sky). The D45 had a weird pattern effect because of the antireflective coating, it seems that they've used less of the coating on the D56 screen. Also there are no side speakers as standard since the base unit contains the sub and speakers (2.1). However it still has the side speaker sockets so i assume you can buy the speakers seperately and add them but i have no idea why you'd want to :s Any other questions; just ask.
