Read a lot in advance on the projector, must say am absolutely thrilled. PS4 games run total liquid without Rainbows, like watching movies. We use it on a diagonal 2,90 Visivo 921945 - Electric Screen LUSSO (260 x 218 cm) 16: 9 Fixed Ca 4m away from the screen to the ceiling. And the picture is definitely better than in most cinemas. For 3D I can not comment as this pretty little interested me.
For sound: Yes, a projector has a fan can be heard ... But not if you watched a movie or playing a game. Solang you look at the menu is reminds me of this fan on my old Asus laptop ... you can hear it but once you play is all forgotten. This is good value for you do with this device everything right. Therefore, 10 of 5 stars :-)
