IMHO opinion, the 436XDE is one of those screen that flies in the face of the "1080p" debate.
My mate has one, hooked up to SkyHD and it looks amazing. Crystal clear, rich colours, razor-sharp detail.
Easily a match for a 46" Sony 1080 LCD that I've also seen on numerous occasions.
And the 436 is (according to some) ONLY HD Ready.
Get SkyHD...you won't regret it.
