So then when watching 1080p 3D on a Samsung LCD, with motion interpolation off, I'm not getting 1080p, but rather only 300-400 lines? That sounds pretty bad - so then why does the active look so much better than the passive, even with motion interpolation off? You can clearly see the black lines on a passive set - with active the image looks sharp and clear with no jaggies.
I was reading this about the F8000 on HDTVTest under motion resolution:
"As with previous Samsung LED LCDs, the Samsung UE55F8000 can show all 1080 lines in a scrolling resolution test chart, provided that the [Motion Plus] system is engaged. With this feature off, you’ll see the usual LCD motion performance, which delivers just 300 lines worth of clear details. That’s enough for 24fps movies to appear without much in the way of discernable blur, but fast, high motion content like televised sports will still appear with some."
Is this what you mean? It sounds like even in 2D the F8000 doesn't show more than 300 lines of resolution in motion without using motion interpolation. I'm still not sure what that means exactly - if it's a 1080p set, why is only 300 lines of resolution being displayed during motion? I'm confused. Is this because of the blur caused by the LCD tech, so that you can only make out 300 lines sharply?
