I purchase this projtor base on the mostly positive review . First of all please note that this be not a hd projector . it simply accept hd signal via HDMI for example and the video signal be be downsize to VGA picture quality . furthermore , the color be completely off . I be debate with myself if it be worth it to send it back and get another projector and ask friend who be over and the verdict be that this hurt they eye . do you research and be aware of these factor . if you want a better picture , then simply go with a name brand .
