| Personal Experience |
| I install and maintain these projectors in conference and control rooms at a very large computer manufacturing company in Texas. The 4100MP is suitable for a medium to large meeting room environment (30-300 people). I would not recommend them for heavy use environments though such as a control room or other place where the projector will be run more than 3-5 hours at a time. The projector's ventilation system is not adequate for such use. They will overheat and burn out lamps much faster than under normal uses of 1-3 hours at a time. |

| Problems |
| Like all the current Dell projectors, the 4100MP has a permanent lens shift ALL the way up to the top of the lens, meaning that when setting the projector on a flat surface, the image is projected way above the unit on the wall. This causes problems if you are mounting the unit on a ceiling, as the projector must be physically angled up toward the ceiling and then the image must be keystoned back to square, distorting the image. The projector annoyingly detects the type of signal input and then attempts to "optimize" the color output. For instance, if you plug in a PC, it vastly distorts color output in an effort to boost contrast for viewing detailed graphics like charts and spreadsheets. The remote control is not IR, but rather radio-frequency with no option to disable the receiver. So if you have multiple 4100MPs installed in nearby proximity, you must perform the RF Learning procedure on each one in order to prevent someone from the next meeting room over from controlling the projector in your room. I have sent many of these projectors back for repair to the system fan which may begin to make a loud grinding noise. There is also no air filter in the unit, so if the projector is used in a dusty environment, it will take in dust like a vaccum cleaner. |
