Have long thought and made me smart on the internet what I need and want at all. This projector is the 800 * 600 resolution Ideal for a wall distance of 4 to 5 meters! At 6 meters the image is still sharp but you can already clearly see the pixels. But since I do not need 6 meters I have a really great image which is very bright and I can see no rainbow for the life which some DLP projector yes should have! 3 D Works well over HDMI with the BenQ Lunettes 3D! These glasses are not present on the purchase and I find the price for this too expensive for a spectacle of almost 70 euro, which has nothing to do with the projector! The sharpness is Extremely well. What I did not know this is such a video projector is capable 2 movies in a row looked the living room with me 30sqm on heating; Hot) Real part !! Fan runs very quietly. Overall a good priced entry-level device which I highly recommend !! Dignity I will buy again.
