W4000 Too dark - where to now?

Folks - cannot live with the lack of shadow detail on my 46W4000 and hope to return it.

Blacks are amazing - but they are too black and often movies/images that i know well are way too dark in dark areas. I can do nothing to enhance shadow detail having tried every trick on here and various forums.

So, where to now? i watch movies and SD TV also do a lot of gaming.

I think i maybe should have gone with a panny plasma as i had first thought and not worried about the brightness strobing. At least i could have seen some detail in the background!

any thoughts?
