Projector Issues

Setting up well in advance of your presentation is not just in case you have computer problems. The projector itself could have issues.

Possible Projector Issues:

Missing Video Cable (VGA/S-Video/Composite) or Power Cord - Always check before leaving the office

Menu Challenges - When menus are used by many users, sometimes what one sets is not good for another. Sometimes features necessary for simple setup are turned off by a previous user. (Such as having the automatic "toggle" button that toggles through types of video feeds turned off). Keystone correction is necessary. Mirror or "rear projection" can frustrate you if the setting has been left on but you are not using a rear projection screen.

These menu challenges allow include "keystoning." This distortion of your projected image occurs when the projector lamp sits at a different angle (most often tilted upward on an horizontal axis) than does the screen. This results in a trapezoidal effect where the bottom of the image is narrower than the top. Most projectors have a menu choice called "keystoning" to compensate for this. This menu item has a scale for incremental (step by step/fine tuning) adjustments.

Burned out projector lamp - not has common as it once was, but still may happen. At $500 or more per replacement lamp, it may be best not to carry a spare, but to pre-arrange the use of a back up projector.(According to industry insiders, projector lamps also have a tendency to loose up to 10% of their lumen power per year of regular (several hours per week on average) use. Improved technologies are lessening this fading effect, but it is still with us.)
