I am Dutch so my German is not very good but I can understand the basics so here is a small summary about the German review:
First he explains the difference between a normal DLP and the new Hybrid, pointing out the lamps, wheel and in the hybrid 2 led and blue laser with green phosfor.
Then he states the loudness is medium, not very quiet but not too loud either.
Then he states the projector has a maximum lumen output of 1400 lumen with a contrast ratio of , sorry cant hear exactly what he says but I think he says 1180:1. He says they are reasonable values and makes it usable under house light conditions
Not so good is the (I think) resolution of black values, which means in dark scenes you don't have much contrast in blacklevels. He states with some finetuning you can correct this quite a bit by changing contrast to 45 and brightness to 62.
similarly he the color was not optimal (rough translation) and especially the green was too much in the yellow area of the color triangle which he shows in the next picture.
There is no rainbow effect or green shift
power consumption normal DLP is 300W where the acer is below 100
within 6 seconds it is off an can be disconnected.
Then he sums up the specs and says they are about right, not so impressed with the design.
Then he summarizes he finds this new technology very interesting but that this device has too many "teething problems (best quick translation I got)" and then he explains why he throws it away: He thinks 1700 euro is just too much money for a unit like this.
Hope this helps a bit.
