I picked up a PN58B850 this weekend (the deal was just too good to pass up) It does really sucks that Samsung won't sell the 860 here in Canada.
The Canadian 850 is no different than the U.S. 850 in that Cinema Smooth is not mentioned anywhere on the box or the TV, It's only mentioned in the manual where it specifies Cinema Smooth is available on the 860 only; although I did go into the Service menu and turn 24x4 on.
The Sammy is replacing a 5 year old 50Sony GWIII.
My first impressions are that the picture (blu-ray specifically) is absolutely stunning, the color, clarity and detail are amazing .
The TV is hung flat on the wall and I find reflections are a bit annoying until the sun goes down, I have a number of windows along one wall and even with the blinds closed it's distracting.
I've already made a big mistake, after only 5 hrs of use I was foolish enough to watch a movie on my new TV and the black bars (top and bottom) were burned in.
When watching full screen content you have to look REALLY hard to find it and maybe because I'm obsessing over it I do think I see it occasionally.
I've been running the scrolling bars to try and fix this burn in problem and even while watching the scrolling bars pass right to left I have to look to see the burn in.
While running the scrolling bars I have noticed one other major issue and that is a pink band across the very bottom of the screen it's around ½ to 1 inch wide and more pronounced just above the Samsung logo (center of the screen).
I find it's only noticeable on white so I saw it a lot while watching the season finally of Gray's Anatomy (too many white lab coats).
Now some questions:
I have the TV set to movie mode (warm2).
How do I prevent any more burn in, yes for the next 200+ hrs I will try to stretch or zoom (if needed) any content that doesn't fill the screen (if the TV, PVR or Blu-Ray will let me) what else can I do?
Although my speakers are shielded will magnetic fields affect a plasma screen?
Should I (do I really need to) put the Ferrite magnets that came with the TV on the power cable (and the Ethernet cable), my HDMI already has one?
