On my Dell 3400MP projector I have a black line going all the way across the image about two thirds of the way down. It is there whether my computer is connected to it or not. Any ideas?

SOURCE: I have a Dell 3400MP Projector. When I plug it

Hi
This is because the screen resolution on the laptop is much higher than the maximum supported by the projector. Try dropping your screen resolution on the laptop to 800 x 600 before plugging in the projector
Cheers

SOURCE: Dell 3400mp Projector is flickering

Hello. Based on the video, return the projector and get a new one since it is still under warranty. The symptom has nothing to do with the lamp or connections. It appears to be an image processing problem on the main board. The blank part isn't distorted or scrambled, it's MISSING!

Download the manual from the Dell site and see what it is from there. But if the previous owner changed it then you're out of luck.

Mounting the Projector from the Ceiling


Projectors, in general want to project the bottom of the image 1 foot above the lens at a typical range. When mounted upside down, they project the top of the image 1 foot below the center of the lens. If you don't want to turn the projector over, you'll have to change the angle and probably go to the extreme on the keystone correction.
