From what I gather it seems to be just an anti reflective coating, is that all that it is? Samsungs website lists the c8000 as 7M:1 CR and the c7000/c6500 as 5M:1 CR. The only difference between these as far as Contrast Ratio seems to be the Real Black filter but here is the part I don't get. If the real black filter is just an anti reflective coating then how would it increase the overall contrast ratio in general. If you have all 3 of the TV's in a completely dark basement the real black filter won't have any effect on the picture because there are no reflections to reduce so how would the c8000 have a better contrast ratio then? For the real black filter to make the contrast ratio +2M:1 it has to be doing something more then just being an anti reflective coating either that or it is just an AR filter and Samsung is just saying it has a better contrast ratio cause it handles bright rooms better but doesn't actually have a better contrast ratio when all the TVs are in a light controlled room.


Any opinions or insight into this?

contrast is nothing more than advertising. That samsung in the real world barely has 2000:1

It's a filter that is really black. It has no effect on actual black level but increases apparent contrast ratio under bright lighting.

As has been said, these mega dynamic CR's are simply marketing.


The HDGuru reviews of the C8000 and VT25 mentioned that both TVs attenuate off-axis light in a similar fashion. Their VT25 review stated that Panasonic is using a micro-louvered anti-glare filter bonded directly to the glass (basically a privacy filter you'd see on a laptop screen, but rotated 90 deg). The black filter on the 8000 would appear to work similarly, as glare is diminshed at the expense of a somewhat narrower vertical viewing angle.


In terms of more realistic #'s, I know ChadB measured a checkerboard CR of 3050:1 on the PN63C7000.

Home Theater Mag reported a Full-On/Full-Off Contrast Ratio of 4274:1 on the PN58C7000.
