| 740406 | 2009-01-20 01:54:00 | Hi guys, I have a NE MT800G projector. it works fine except for the fact that the lens has a huge level of magnification... I think that's what it's called.... in other words the projector needs to be place a helluva distance from the screen... i'm talking 20m + here. What I want to know is... Is it possible to change the lens so that it can be used at a close range. I have checked the zoom on the projector and that had been set to normal, but I can't get it smaller... even on it's lowest setting the projected image cannot be seen properly. Any suggestions will be great. Thanks. |

| 740408 | 2009-01-20 02:45:00 | How long have you had it. Most projectors get bigger the further you get away from the screen, are you saying at 5 metres the screen is to small. On the lense itself it should have a fine adjustment for clarity and a zoom adjustment aswell to make the screen size smaller and larger. By soom I mean through the lense not digital zoom like in the options screen |

| 740409 | 2009-01-20 19:18:00 | Hi chief, its called a throw distance......my Sony S20 is around 3-4 meters for 100". I'm not sure how you would go about changing the throw distance via the lens as you are correct in thinking the focus will play a part in the equation also..... 20m sure is along distance, is that a commercial projector for halls or something?.... |

The image get's smaller the closer you have it to the screen as well as more out of focus. Having said that... I spoke to the guys at NEC who told me they can change the lamp and adjust the projector to suit but this is more expensive than actually purchasing a new projector... so I guess that's what i'll do now.. look for a new unit. thanks for your rsponses. Cheers, |
