Chapter 4 The Web Configurator Screens

WPA-1000 User’s Guide

The following table shows you the number of pixels that are displayed in each resolution.

The total number of pixels a projector can project depends on its resolution. For example, an

SVGA projector can display 480,000 pixels at a time.

Resolution affects how sharp your image is and the compatibility of your projector with your

WPA-1000. If the WPA-1000 is sending a signal to the projector that is XGA, and your

projector has SVGA resolution, there may be display or hardware problems, so it’s best to

select the resolution on the WPA-1000 that your projector supports.

LABEL DESCRIPTION

Projection Setup

Output Resolution Resolution is the number of pixels that the projector is capable of displaying.

Select the resolution that your projector supports and displays best.

Color Depth Color depth is the number of bits used for each pixel on a screen. Select the

color depth that your projector supports.

Screen Refresh

Rate

The refresh rate is the number of times that the image on the screen is drawn

each second. If your projector has a refresh rate of 72 Hertz (Hz), then it cycles

through all the pixels from top to bottom 72 times a second.

A higher refresh rate reduces screen flicker and reduces eye strain. However, if

you specify a refresh rate that is too high for your projector, you may damage it.

Also, there is a trade-off between refresh rate and resolution. Select the refresh

rate that your projector supports.
