The ViewSonic PJ820 Office Theater
TM
projector can run at an
extensive range of resolutions and refresh rates. Certain standard
resolutions are factory preset. There are also six timings which are
user definable. For example, if your video card is set up to run 1024
pixels x 768 lines at a 75 Hz refresh rate, once you have adjusted
the projector size and position to your preferences, the PJ820 saves
this information to memory. Every time you run this resolution at
this refresh rate, the projector recalls your adjustments.
The following table lists the maximum refresh rates that the
ViewSonic PJ820 will operate at a number of standard resolutions.
While the PJ820 is capable of this level of performance, not all
video cards are capable of running at these refresh rates. See your
video card user's guide to ensure compatibility.
