I need to check but think I have the H,not much of an upgrade really, I think it's very similar to my eyes when I saw it in store,perhaps because the H still had a glossy screen and the N has a matt screen
The U8N definitely seems far superior,colours and blacks pop out at you so the contrast is a big upgrade and the brightness too...waterfall Hirschs have their TV's in a relatively bright area with natural sunlight coming through from the roof which is very similar to my lounge with large 5m floor to ceiling windows on one side and a bright dining room on the other side,this allowed me to see what they would actually look like for my usage, glad they done that instead of so many stores which only have their TV's in dark areas.
