That usually means you need some eye correction or are not sat square on.
The focus point with 3D is quite important.

Same here on my VT50. Ive watched every major 3D release at the IMAX for about ten years and my VT50 blows them all away for clarity. However, viewing position is important as are the surroundings... you need the room dark with no peripheral interference to maximize the experience.

The new documentaries on Sky 3D are very good too. Not HD of course but still pretty good it has to be said. My youngest loves Dinosaur documentaries in 3D... its a nice extra dimension for her.

Eye correction was fine, and the missus is 20/20 anyway. We were also dead centre when we tried it out; it's just that the active shutter effect was quite noticeable and unpleasant.

Odd one - maybe an anomaly with your own system setup, i have never experienced it with any set Ive tried, but they have all been Panasonics.

It was a pretty simple setup - Sky HD box plugged into HDMI3, Sky 3D chosen as the channel, 3D turned on. Static shots were ok, but anything with fast pans was just rubbish.

I do wonder if it's a framerate issue as it wasn't as bad when I tried a bit of 3D gaming from the PC (nVidia's 3DTV Play vision), but only when running 720p@60fps; 1080p@24fps was also rubbish, but seeing as 3DTV Play doesn't supports 1080p@60fps 3D, I got bored of it and put the glasses away again.

Ah.. didn't realise it was mainly Sky TV's 3D. True HD 3D at 24P and Sky really are worlds apart. Ive never researched issues from the twin image system they use though as I rarely use it and it doeskin cause "me" any issues. One things for certain though, its a known fact that about 15% of humans have poor binocular vision and this means due to how hard 3D makes the eyes work, these people can only see blurry images instead of 3D effects and it often causes bad headaches

Love mine! I'm On a year old lg passive 3d tv with pioneer 3d bluray player, enjoyed some great documentaries on it. Even the 2d to 3d conversion software does a decent job. All about your positioning in my experience with it.

Framerate is always a factor. Especially with shutter glasses you get your two images, which form a stereoscopic image, in sequence. The slower the shutter speed is, the more distance you travel between those two images on a fast panning shot. It's a bit like those line tearing effects you could get with the "i" HD video modes.
The reason why 3DTV Play doesn't show 1080p@60hz is most likely a hardware thing. Only HDMI 2.0 (Released in September 2013) is able to show 1080p "3D" at 48hz (also sometimes referred to as "1080p 3D HFR"). You are most likely using HDMI 1.4(a) on your hardware which only has about half the bandwidth of 2.0 hence only 1080p@24hz.

Concerning 3D quality... As Stu mentioned, the viewer's position is key for correct stereo images. With current technology you have most likely only 1 really correct position, which is (in simple terms) exactly at the point between the two cameras filming a scene. This is why people put a lot of effort into tracking a users' head when using Virtual Reality technology. Knowing this, you can imagine that producing stereo images for cinemas is not that easy, when people are sitting easily up to 20m away from each other. Therefore, leaving display size out of the assumption, you can assume, that stereo images shown at a cinema are theoretically worse than at home. And that those at home are worse than in a fully head tracked, single-user VR environment.

Interesting info mate, thanks for your input.

Apparently HDMI 1.4b added support for 1080p@120Hz, which would naturally translate to 3D 1080p@60Hz. I suspect that the WT50 doesn't accept it as an input, even though the panel itself is capable.

To be honest, this is why I wish Displayport was standard fit on modern TVs. Using HDMI seems so...archaic.

I think this is not entirely correct on the english Wikipedia and purely based on the linked video there.
As far as I can see, the secondary video modes for the 1.4a and 1.4b standards are exactly the same (Changelog for 1.4b says "Several minor editorials and clarifications (throughout)"). Meaning that 1080p@120hz or "1920x1080p @ 59.94/60Hz (Frame Packing, Side-by-Side(Half))" for 3D already existed in 1.4a (see Point 8.2.3.2 of the spec). The bare minimum for a device supporting 3D over HDMI is just to support one of the resolutions: 1080p@23.98Hz/24Hz, 1080i@60 or 50 Hz, 720p@60 or 50Hz. Since this is the only requirement, most vendors will probably just implement these basic formats to maximize compatibility. Secondary modes are vendor specific and therefore possible but not required.
On a sidenote: Although I might misread the specification, even the modern consumer graphics cards (Nvidia Titan/AMD R9) only use HDMI 1.4a which is why I added the (a) to the 3DTV part.
I give you that I could be wrong with my previous statement naming the bandwidth as the limiting factor for only having 24Hz. I haven't done the calculations there by myself, sorry.
