Timing Chart The following table lists the maximum refresh rates that the ViewSonic PJL855 will operate at a number of standard resolutions (timing presets). While the projector is capable of this level of performance, not all video cards are capable of operating at these signal timings. See your graphics card user's guide to ensure compatibility.

Some input sources may not display in full size, as shown in Output Resolutions. Connecting to the RS232 Port The RS232C Port has two possible uses: 1 Mouse Emulation This allows you to use a mouse with one computer at a time, by toggling between one computer connected to RGB1 and another computer connected to RGB2. NOTE: Depending on which type of mouse you will be using (PS/2, ADB, or Serial) you must use the appropriate connector. (See diagrams below) 2 Computer Control Port This is only used for special applications in which a computer controls the projector (instead of the projector's control buttons or Remote Control Unit). NOTE: To use this feature you must first develop customized software using various control codes. To find out how to access this supplementary information, contact ViewSonic Customer Support. (See the back of this guide.) Mouse Emulation (a) 1 With both the projector and the computer powered OFF, connect the projector and the mouse terminal of the computer using the appropriate cable. (See diagrams to the right). 2 Disconnect the existing mouse. 3 Power ON the projector, then power ON the computer. NOTE: If mouse emulation will not start, reset the computer and/or check the mouse driver.
