Definitely getting me interested too.
What does it mean by black level is 400 per cent better! How can that be, 400 per cent?
See, I knew you'd come around in the end!
With creative mathematics, advertisers can pretty much say anything they like. Just look at manufacturers' LED TV contrast claims. Samsung's F8500 black level claim was relative to the E8000's performance, and the F8500 certainly goes much blacker than that.
Bear in mind that the 0.001 and 0.004 ANSI figures in the review are foot lambert readings (rather than the candela per square metre readings used in UK reviews). Converted, and using the UK review figures for comparison, those figures equal in candela per square metre:
F8500: 0.0034 (full black screen) and 0.013 (ANSI checkerboard)
VT50: 0.009 (full black screen) and 0.012 (ANSI checkerboard)
If we use the ANSI reading, which of course we should as this reflects black level with content on screen, there's essentially no difference between these TVs. All of that assumes no variance between tests in different environments (albeit using the same meter).
I honestly don't think the black level conversation is worth having. The TVs seemingly match each other in this regard and it would be impossible to tell them apart. That said, the F8500 reading is out of the box and may be lower once the TV has bedded in.
In other regards, motion and shadow detail especially, the F8500 looks a better TV than the VT50. 3D performance is better, too, as the F8500 can produce much brighter 3D images. While many people don't care, it's good to know that the TV will get the best out of 3D Blu-rays.
It seems we're in a position now where Panasonic and Samsung plasmas are so close in terms of performance that any decision comes down to small preferences, or problems reported. If the F8500 has perfect screen uniformity and better motion, I think that's where my money will go.
I also think the F8500 looks sexier than the VT50/60. And there's no annoying, distracting light on the front when the power is turned on. A small detail, yes, but in a dark room that green light can be annoying.
Excuse the mini-essay! These are really just my thoughts spilling onto the page...
