I've just recently received an NW-HD5HS and I wanted to have the screen Black with White text like the unit depicted on the box and in these pictures: http://shop.sonystyle-europe.com/catalog/42/4294F9EB545500D6000000002BC29B8F.jpg http://www.unbeatable.co.uk/resources/images/products/0032700/0032794_03_lrg.jpg I've changed the "Invert Screen" option to "Negative" but adjusting the contrast I can't seem to get the screen black. The closest I get is a sort of dolphin grey. This is a little annoying as on my NW-HD1 you can get a crystal clear dark green screen with light green text. I guess this is either a problem with my unit or I could have set it up incorrectly or, finally, the pictures are misleading and it is not possible. Any thoughts please?
