You won't see crosstalk unless there's an object in 3D space in front of the screen plane or behind it, and in the area where the crosstalk occurs. So, if your FPR has a bad spot in the lower right corner, and there's an object that's far off in the background there (or popping out), you'll see a double image. If the object in that area is at the screen plane, the left and right images overlap without any separation. Without separation, you won't notice crosstalk. It's there, but it's going to be virtually impossible to see.
You'll see ghosting virtually anywhere the FPR is bad, but only if the left and right images diverge on the screen in the malfunctioning area. The 3D may look perfect in one scene, but look terrible in the next. That's why using the 3D controls from the menu may appear to fix ghosting, when all they're really doing is shifting the divergent left/right images so they overlap. Since it's impossible to predict where objects are going to be in 3D space at any given point in time, the ghosting is certain to become visible again later - in the same area you just "fixed."
The moral of the story is that no menu adjustment or board swap will fix a bad FPR. If you're viewing from passive 3D's sweet spot, you probably won't see much if any ghosting on these OLEDs if the FPR is working properly. You can use the jpg I posted earlier to test for a defective FPR, or you can make one yourself in any paint program. Create an image that's pure black on one side and pure white on the other. (For those of you doing the math, that's 1920x2160 of black on one side and 1920x2160 of white on the other.) Save it to a flash drive and plug it into a USB port on the E6/G6/C6. Play it and engage side by side 3D. View from your normal viewing position, but keep in mind you'll see bad 3D unless you're in the sweet spot, vertically perpendicular to the center of the screen. If the FPR is bad, you'll notice it right away. It's unlikely that the screen will be perfect, but as long as it's fairly uniform, you'll probably be OK. There are plenty of examples of good and bad FPRs in this thread. Just scan back through the pages and you'll find them pretty easily.
If you want to show a tech your FPR is bad, this simple test is a good start. It provides objective proof of the defective areas. I showed my LG tech the test image, then put on a commercial movie that showed ghosting in exactly the areas the test identified.
