Ordinarily, because of the way that 3D images have to be displayed on a TV screen to be viewed via passive glasses, resolution is reduced from 1080p to about 540p. In other words, the trade-off is usually less expensive, and more comfortable, 3D glasses, with "flicker-free" viewing, at the expense of full 1080p 3D resolution. However, on the 55LW9800, LG is "boldly claiming" that its FPR system provides full 1080p resolution for both 2D and 3D viewing, while still using passive glasses. However, this is still a point of contention amongst reviewers and industry professionals. For more info on LG's 1080p 3D claim, check out the official LG 55LW9800 product page.
However, resolution isn't the only thing that is important in TV viewing: color accuracy, cross-talk, viewing angles, and video processing performance are also important, and the 55LW9800 passed the THX certification tests for both 2D and 3D in those, and other areas. In addition to both 3D and 2D viewing the LG 55LW9800 is also a fully-equipped Smart TV with ability to access a variety of network and internet-based content, including Netflix, Amazon Instant Video, Hulu Plus, and MOG. The 55LW9800 also comes with four pairs of 3D glasses.

According to LG, 3D is presented in FULL HD 1080P.

Interesting claim – there are only two ways to accomplish that with an LCD TV using a
passive glasses system with 3D:
1. The TV would have to have a 4K native pixel resolution.
2. The TV screen itself would have to have active shutter properties – which, as far as
I know is only in prototype stage.
I actually saw this set up and running at the recent CEDIA EXPO and neither
technology was mentioned for this set.
I have placed some further inquiries for clarification – If the LG website is correct – I will update my blog post.

I have placed an inquiry with LG, but have also reviewed my own information on this topic as well as making inquiries to colleagues and would like to refer to a source that explains why a 1080p 3D LCD TV using the Passive Glasses system does not display 1080p in 3D mode.

If LG has additional information to rebut this, I will definitely pass it along.

Fact is, its not full 1080p 3D but personally don’t care. The viewing experience is 10x better with passive 3d imo. I’ve owned two high-end samsung active 3d plasmas, and sampled other active sets at best buy. When I finally saw the cinema 3d I was blown away.. by the 3d effect, the lack of ghosting, and the feathery lightness of the glasses. Its just a more relaxing experience as well. Hardly noticed the fact that the resolution was lower. The benefits crush the drawbacks.
