Setting Up the Projector 21
Connecting to a High-End Workstation
Your PowerLite projector is capable of remapping input resolutions
up to 1600
× 1200 pixels (on the PowerLite 74c) or up to
1280 × 1024 pixels (on the PowerLite 54c). Since 1280 × 1024 pixels
is the default resolution for most leading workstations, your projector
is ideal for displaying workstation video output.
There is no standard for workstation video output. Workstations that
follow the SXGA standard and use the HD15 (standard VGA)
connector won’t need an adapter cable or any special connection
device. However, your system may vary; contact your computer dealer
if you need help connecting your workstation.
