I am going to buy a new Philips 42" LCD in the not too distant future and according to the spec it has a a VESA 600 x 400mm fitting. The TV weighs around 45kg and will be mounted on a solid brick wall. There will be a white panel standing off the wall by an inch or two (for ambilight display) and my idea is to have the mount coming from the wall, through a hole in the panel and attached to the TV. The TV can then be pushed back to near enough flush with the panel and the cabling (1 HDMI and AC) will go between the wall and the panel out of sight. That's the plan anyway.
I went looking for mounts and after a bit of research have decided that a cantilever mount would be the best solution for my installation as it will allow easy access to the connections at the rear whilst still being able to be wall mounted. I like the look of something like the Omnimount UCL-L and UAM combination but I don't think it goes as big as VESA 600 x 400. I also note that it doesn't fold particularly flat to the wall (172mm).
Anyone care to recommend any good cantilever wall mounts with a 600 x 400mm VESA fitting and relatively low profile (2-3 inches ideally) when retracted that I should consider.
