1) suitable for daylight
2) less than 30 db Betriebsgeräuch
3) Farbtreu => LCD projector
4) The highest possible resolution (Full HD)
5) Lens shift
The projector is in Eco mode exterm quiet (22db). The power zoom is very useful if you want to mount it on the ceiling.
The projector was too dark for daylight projection (for it is not made).
Ultimately, I decided with the current model Panasonic PT VZ 575 (N) from the Buisness series and am very happy with it, both in daylight and in Cinema mode.
The picture is again much sharper and the colors crisp (in conjunction with the BlueRay player Yamaha BD A 1040).
I would give for the Panasonic PT AT 6000E therefore in direct comparison three and a half points for the PT 575 N VZ five points.
Possible alternatives:
Epson EB 1980 WU - is in Eco mode louder than 30 db
Epson TW 6600 - has only 2500 lumens brightness
