The only drawback:
The volume of the fan. This is really quite loud. And with quite loud, I mean that one hears him extremely.
When we watch a movie and the Harman-Kardon system deafened, you can tell them anything.
Let's play but titles like Resident Evil where meantime peaceful scenes are, you can hear a very loud fan.
But I can live with, with a screen size of 110 inches ^^ muhahaha
3D
For the 3D enjoyment, I use the Blue Heaven 6th Gen. Picture is great and I feel it with the glasses not too dark as I've seen it in some TV sets.
On the whole, I am very satisfied. VLT. let me, I also think of something with respect to the fan. ;-)
Update there if I found something clever. :-)
