Presentations in business still use the CRT projector. The Cathode Ray Tube (CRT) projector uses three small cathode ray tubes, each for a primary color. CRT projectors use a magnifying lens to project large color images onto a screen. Today’s CRT video projectors offer very high resolution images.
CRT projectors have many advantages over less expensive and more portable LCD (Liquid Crystal Display)and DLP (Digital Light Processing) projectors. Unlike these less expensive projectors, CRT projectors offer better resolution and higher quality images. Also, if you select a CRT projector you will not have to replace the light source as often as you would if you had purchased another projection technology.
If you are thinking of buying a CRT projector for your business, you will want to consider:
1. Budgeting for your purchase, since CRT projectors can be expensive.
2. Planning your meetings in a dark room, as a CRT projector needs complete darkness to function.
3. Creating a separate meeting area where you can keep your CRT video projector, since it will not be very portable.
Plan to install a CRT projector in your meeting areaSince some CRT video projectors are not very flexible, set up your meeting area before making a purchase. You must set up a very dark room for your presentations, since CRT projection works best is very dim lighting. You should also create a permanent space for your CRT projector; these projectors are large and bulky and you don't want to have to tote them from one place to another.
Look for the right CRT projector featuresIf you plan on using your CRT projector system to show PowerPoint presentations, look for a CRT projector for sale that has at least an SVGA (800 x 600) resolution.
