My conclusion: it is not as bad as it appears here.
However, I use a 3DTV (brand Philips 9705), from the 2010-series he who unfortunately had no 2D-3D conversion. (And at a price of 2.500, -)
The shutter glasses technology definitely comes a 3D effect, which differs significantly from the 2D image.
Furthermore, I also did not detect a headache, dizziness, although with the shutter glasses very often the case.
(I had 1.5 years ago a Samsung LE C750, which had a 3D conversion, and as a headache, dizziness was always an issue) btw. the Samsung TV produces a better 3D image from the 2D-3D conversion, and a deeper 3D effect, but it was just connected with dizziness, so look about 10-15 minutes, so 3D look for hours was absolutely impossible.
The box that is not the case, even after prolonged look.
The 3D effects of course can not get into a new 3D Blue Ray, but the film has since also specially produced using 3D technology.
(By the way I can this 3d Blue rays for hours look 3D, without any headaches, dizziness.
When 3d blue ray "coral reef", for example. Kommte a sea turtle right on too, and then swims in Principle 2 meters in front of the TV, such effects come with the box not materialize (but also from the movie dependent would be interesting to see as the effect of a 2D Blue ray with the conversion comes across)
The 3D effect can also increase, decrease (3 levels), I liked the minimum effect on the best, just because you do not have vertigo.
What's going on with me this box is that you can not regulate the depth adjustment. (The Samsung TV, you could see the 3D depth in 10 different stages show), and got quite the impression that the television is at least 50-60 cm thick (= low), so intense was the 3D effect.
That you can not regulate the depth, is a shortcoming in this box.
Whether that comes with other boxes, I do not (eg. The AB 3D box), but it costs more than twice this box, and I was very skeptical about whether it überhautpt an effect brings, so I resorted to cheap variant ,
I would also like to mention that I have seen and only converts at least HD television broadcasts, even better, sending Servus TV even in 1900x1200.
At low resolutions such as 576i, the quality of the 3D transformation is getting worse.
In addition, it also depends on what film or what program you look, diverse wildlife films in HD, documentaries such as Hubble universe, Swiss TV landscapes are to relatively well.
The traditional, old 3D technology is the way better than generally described.
I have seen the film "Journey to the Center of the Earth" on blue ray (but not 3D Blue Ray), and with conventional, old paper glasses. The 3D effect was not worse than the movie "Pirates Carebbian" I have to 3D, and who has really let me down by the effect her.
The one with the herkömml "cozy 3d glasses, I also tried it with this box, also there is an effect there, but I have to agree that is lost through the red and blue glasses a lot of color effects, which I with the shutter spectacles technology still have.
So who already has a 3D-capable TV, have a clear advantage with this box.
My Conclusion:
All in all I give the box a. 3
If you already have a 3D-capable TV, the 2D to 3D conversion is missing, this box is quite an alternative to look any broadcasts in 3D.
Cheap way to look despite the lack of 2D-3D conversion on the TV 3d can. (And biliger than the Philips 9706 to buy, which is not, in principle, better than the 9705-ies, but it is a good 2D-3D conversion has.
Myself would be interested in how well the 3d Box AB or the Koenig 3D box cut here compared to this, and if the additional financial costs (150, - or 137, - Euro as compared to 69, - a lot more brings.
I hope I was able to contribute to an easier purchase decision somewhat.
Update:
Have the unit now tested two days intensively, convert 8-10 hours at a time 2D-3D broadcasts and enjoyed, and without any headache, dizziness, so I have to correct my vote even upwards, and give the device a 4, only the inability of depth adjustment prevents rating by 5.
The device can definitely convert 2d to 3d, yesterday the film "Pirates Carebbian", which is available in the Blu-ray box both in 3D and in 2D, viewed in 2D, and can convert the box 3d, it was To see absolutely no difference to the 3D movie;
Since I have taken many broadcasts on the digital cable box, and could often take up these documents only with 576i (NTV, N24, ZDF Neo, etc.), the pictures are not as good as with HD broadcasts; but since I can control the image output, and thus the 576i can be extrapolated to 1280i, a 3D output on the TV with the shutter glasses is even possible here, and even in this case a significant 3D effect is visible. (The TV turns off only a minimum resolution of 1280 automatically to 3D, but with the extrapolation, it is possible.
I am pleasantly surprised by the device, 3D television for dumping price.
