well I went to the store today to see the hdtv's and I think it is my eyes since I noticed the same thing on their hdtv's and I saw two different ones, panasonic and lg, they had a sony and samsung but, I already have a sony so didn't need to check it and the samsung wasn't working.
i believe with the lg (passive) it was a little less but, it was still there I don't have problem seeing depth but, when the 3d is supposed to "come at you" or look like it's coming out of the screen is when my eyes lose focus I don't know maybe I'm new to it (even though it didn't happen the first time I saw a 3d movie) that I guess my eyes/brain can't tell what to focus on when the 3d happens and maybe my brain gets confused lol that's the reason I start feeling like I'm cross eyed.
The only thing is that I've never liked the picture on an LG, we have 2 LG's here (non-3d) and I don't know why the image looks a little more pixelated or something to me, all the other hdtv's look like they have a cleaner image than LG to me.
also I couldn't really notice much difference in picture quality from brand to brand (except LG) or even LCD, LED and plasma, only thing I noticed was that LED/LCD seems to have a brighter image than plasma. Plasma seemed a little darker, I thought it might be the tv settings at best buy but, then I went to target also and noticed the same thing, maybe they have it at default settings and don't have brightness turned up, I'm not sure would have to research it to see if other people are saying the same thing.
So, I guess unfortunately I can't watch 3d
i'm convinced it's my eyes, I kept trying to stand in different positions to the LG and try to to see it correctly without getting "cross-eyed" when the 3d comes out but, I just couldn't get it. If it happens slowly I seem to adjust but, if it's fast or even normal movement is when I notice it.
Only thing I would say about the LG is that the glasses were much more comfortable since I guess because they're passive (not powered) they're lighter and easier to keep on for long periods of time, the sony active ones I have now start to kind of hurt my nose after a while have to keep adjusting them. If I can find a Toshiba passive 3d somewhere on display I'd like to see that, maybe if the picture is better than the LG then I might consider that for 3d, I'm going to try to see what happens if I watch 3d once in a while if I'll be able to watch it like I was able to when I saw it the first time with Captain America.
This is off topic but, I was wondering instead of making glasses can they not make a screen with the same material that you could put infront of your tv at a certain distance to see the 3d then you wouldn't need to wear these glasses?
