How Video Modes Work
The EPSON 17” multifrequency monitor is equipped with seven
predefined industry-standard video modes to support virtually
any resolution and frequency you may require. However, if the
combination of your computer, video adapter, and application
program requires a nonstandard video mode, your monitor creates
a new, “user-defined” video mode. The monitor chooses the
appropriate mode automatically; you never have to decide when
to use a predefined or user-defined video mode. The monitor can
create and save up to five user-defined video modes. Altogether, it
can store up to 12 video modes (seven predefined and five
user-defined) at a time. For a list of the predefined video modes,
see the “Specifications” section.
