I only tested this on my TV, but, nonetheless, the results were clear and definitive.
Does contrast and cell light settings effect the frequency of pops?
No. There is no correlation between pops and cell light or contrast. In other words, it does not matter how bright and contrasty or dim and dull you set the picture, If a pop happens, they will happen regardless of how these are set. So, I would advise owners to adjust their settings to produce the best possible picture and not make extreme adjustments to limit pops. Pops are simply not triggered by brightness or contrast....these settings have no effect on them. Of course, you won't see them, or anything else, as well with very dim settings.
So what triggers the pops?
It's actually a combination of the color white and movement. All variations of white seemed to be able to produce the pops, except for those that have a yellowish or amber tint to them. which didn't produce a single pop that I could see. Very slow moving or static scenes do not produce pops...you will never see pop in a static picture of the sky, for example, but when the camera moves to pan the sky, that's when pops may occur. With fast movement, like when a camera follows an air plane through sky, the pops can occur in rapid succession, especially when the whites in the sky are broken up with other colors.
Is there more than just one kind of pop?
Yes, I found two types. I'm not sure if both would be considered pops, but both occur as a reaction to the combination of triggering shades of white and movement.
The first type is the one most discussed, a two step adjustment in brightness. You only see this type in the white sections of the screen...the dark sections are not affected. Most everyone know what these look like, so I'll leave it at that.
The second type is more of a flash that occurs much less frequently than the two step type, but effects the entire screen. It happens when the triggering whites appear on various sections of the screen at the same time. For example, on a sunny day on a golf course, the whites will come through the moving leaves of a tree and flicker on the fairway or green, if enough of the whites comes through, the screen will flash. Another example...hockey, which shows the two step pop a lot, when enough players block out enough of the ice, it seems like the set wants to produce the two step pops in just the open ice areas, but can't, so it just flashes the whole screen instead. In other words, if white areas, where the normal two step pops would normally occur, are dispersed enough throughout the screen...in smaller sections...the set just flashes the whole screen instead of producing the two step pops.
There you go...I'm popped out : )
