Projector Matching… What The What???

Projector matching, (in case you are wondering) is important to you…  Similar to the freshman algebra you never thought you would use, with your presentations, projector matching is something you will use every time…

Simply put, if you are using more than one projector for your presentation, you want to make sure that the same make and model are being used on all of the screens at your presentation…  At XPROi A/V, we take it one step further…  We match projection lenses, and bulb life…

There are important reasons for projection matching!!!

The first, is to ensure a uniform look throughout your presentation…  It does you no good, to invest the time and effort into putting on a great event only to have one of your screens significantly dimmer than the other…

The next, is to cut your show labor expense…  If the technicians are using matched equipmant, the amount of set-up time should be decreased…  Time is money, or so they say…

The final reason for projection matching to be discussed here is, that your facilities people will love you for it…  Throw distances (and the show overall) will be symetrical…  As the facilities people are setting up the space for your event, they can set up evenly…

Overhead Lighting, Friend Or Foe?

A recent discussion gave me the opportunity to think about this in-depth.  How many times have you been to a breakfast function or luncheon where the screen was blown out by the overhead lighting?  I know I just raised my hand…

Below are some thoughts on how to plan ahead for your next big meeting!


In putting together meetings and events, the planners I work with are always torn between having the room bright enough to take notes, (20 – 50 footcandles in conference rooms and 10 – 30 footcandles in exposition halls) and dark enough to see the projector (30% of the ambient light* or 6 – 15 footcandles in conference rooms and 3 – 10 foot candles in expo halls.)

Ultimately, it comes down to which is more important.  In some cases, it may possible to dim the room lights during the video presentation portion of the event.  In some cases, a bigger, brighter projector will overcome the room’s overhead lighting.

It is always recommended to place the screen away from any direct overhead lighting.

This is where things may get a bit sticky.  There is usually only one light source, and there is not a very handy method to dim it.  The outdoor projectionist’s motto is “dawn, dusk, or dark! ”  There are a few ways to minimize the impact the sun will have on your presentation.

Plan on doing rear projection, with the screen pointed AWAY from the sunrise or sunset.  I have in the past, built an enclosure covering the “projection pathway.”  (Some sort of tent/pipe and drape/tarp or black plastic/dark, dark, dark, enclosure.)  To allow my client’s presentation to shine.

The last step, is to make sure the projection unit(s) are bright enough to handle the job.  Ultimately a minimum of a 10,000 ansi projector, or two smaller identical units stacked & aligned is my recommendation.

At this point, I’d have to say “overhead lighting is the foe of a nice bright presentation.”  If some forethought is givin in the planning process, the impact on the presentation should be minimal.
