Yes, the viewing angle is a slight drawback. I was sitting about 1 metre away on a low sofa (so my eyes where lower than the centre) and I did see some ghosting at the edges. I tilted the monitor as far forward as I could but couldn't get it quite far enough. I have to sit upright in order to get rid of the blurred edges. I don't see it as too much of a problem though. You can always sit closer and more full on if the ghosting bugs you. From where I sat I would say about 80-90% of the screen showed great 3D.....the central area was fine but the edges had some blurring. I'm still just enjoying the 1080p image so much and enjoying all the various 3D content, YT3D clips, 3D Blu-ray and games, that I'm willing to overlook this one small issue.
Incidentally, a neighbour of mine came around for a demo. I showed her the 3D TV sparkling fun demo, amongst other stuff and her reaction was "It's wonderful!!" She's quite elderly and she told me that she had seen 3D in the cinema back in the 50's and liked it but I think she had only seen the anaglyph 3D as she mentioned the red/cyan glasses. Whatever she had seen before, she was very impressed with the new 3D technology.
I installed the Tridef Driver yesterday and it worked a treat. It recognised a couple of my games "Tiger Woods 08" and "Need for Speed Underground" (Yes I know they're ancient but I'm not much of a gamer) and the driver worked straight away. I only tested the Golf but the default setting was perfect with a nice depth down the fairways and good layering of trees and bushes etc. The only bug was that each time the screen cut to the next tee shot, the left and right sides were separated at first and then join immediately to interlaced. It only lasts a milli-second and isn't too distracting. The driver is very similar to the iz3d driver which I tested with the anaglyph output a few months back. Of course the passive 3D looks much better than the anaglyph, but the 3D depth is similar. It also comes with a Tri-Def Media Player which I don't really need. Stereoscopic Player does everything I need for 3D playback.
