Recently LG released a new firmware bumping me from 3.x to 4.x. I was curious what all the new firmware included and while searching around found out that LG was bumping up the 3D resolution on their passive 3D cinema TVs. http://www.flatpanelshd.com/news.php?subaction=showfull&id=1304582822
Before the Cinema 3D technology worked like this: During a time period of 1/200 seconds the TV showed 2 frames; 540 lines for the left eye and 540 lines for the right eye.
The new algorithm shows 4 frames instead of 2 during the 1/200 second time frame. It shows 1080i for the left eye and 1080i for the right eye.
When these are combined the two pictures create a 1080p picture according to LG. LG believes that this update improves picture quality on their Cinema 3D TVs to compete directly with the active 3D TVs such as 3D plasma TVs. You need to turn off TruMotion to utilize the new algorithm. See the illustration below.
It's nice to see that LG is doing this upgrade for all the current models and not trying to release a new price range model touting this as a new feature. So if any of you have a LG 3D Cinema TV, turn off TruMotion and see if you can tell the difference with the latest firmware.
