Glossary of Terms (click on term for in-depth information)

CRT Size/LC: Although manufacturers measurements will vary, these measurements are the agreed upon measurements by most enthusiasts. Actual raster corner to corner measurements will vary based on the installation. LC is noted for tubes that are liquid-coupled (as opposed to air-coupled). LC'ed tubes offer greater contrast and less halo'ing.

Chassis Controls: Analog chassis projectors use manual "pots" for convergence, image sizing, shift, etc.  With the newer digital convergence feature, convergence is done from the control panel or infrared remote control.  This gives you the ability to stand at the screen and more accurately set up the focus and alignment of the CRT's. Digital convergence units also may have memories for different inputs and aspect ratios.  These can then be changed with the push of a button on the remote.

Peak Lumens: Lumens relate to the amount of energy (light) that's coming from the CRT.  It describes the potential of the projector, but little of the actual brightness you will get on screen.  The brightness depends on many factors.  The most important being the screen size and material as well as ambient light conditions.

Scan Rates and HDTV:  The ability of a projector to display HDTV depends on its scanning capability. For example for a projector to line double standard NTSC signals (480i at 15.75khz horizontal) from DVD, VCR or cable/Satellite to 480p, requires 31.5 Khz of horizontal scan rate and enough bandwidth to handle twice the picture information. HDTV at 1080i requires a horizontal rate of 33.75 Khz and 50 Mhz bandwidth.  720p requires a horizontal rate of 45 Khz with 50 Mhz bandwidth. 

Max resolution: This is the maximum resolution that the projector can accept (and sync to) as an input signal. Important: While the projector may be able accept the signal, it may not be able to fully resolve the information on screen without overlapping of scan lines resulting in a softening of the picture. That is, the manufacturer resolution specifications do not necessarily reflect real world resolving capability.

Inputs: As listed above V = standard composite video, usually a BNC connector on projectors (takes a $2 Radio shack connector to convert back to RCA). S = S-video in its usual form. R = RGB in either a DB type plug or 5 separate RGBHV BNC type connectors. C = Component video.  Any values in ( ) are available with an optional input board.

Zone/Point Convergence: A feature of a digital chassis where after doing a rough convergence you can fine tune various areas of the image for a tighter alignment

Electromagnetic Focus: A feature on newer projectors where you not only have the ability to focus corners and center, but additional electronic controls for fine focus of the beam spot throughout various areas of the image producing a sharper image.
