Recognizing Preset Display Resolutions
The HP f2304 High Definition 23” LCD Monitor supports the
display resolution modes listed in the table below. Some of
these modes may not be available from the video graphics
system used in the computer. Preset modes 20, 22 and 24
supports the f2304 monitor using only the VGA signal input.
If using a DVI signal input, these preset modes will not
properly display although the operating system and video
graphics card may indicate these modes are supported.
Using modes 20, 22 and 24 with a DVI signal may not
display images properly on the screen. If changing
resolution modes does not display images properly, do not
touch your keyboard and 15 seconds later your settings will
revert to the previous resolution mode.
Preset mode 23, 1920 x 1200, is a new video resolution
mode developed for digital monitors that support DVI signal
input using reduced blanking techniques. Before selecting
this new video mode on the f2304 monitor and to avoid
images not displaying properly, refer to the documentation
that comes with the video graphics system to confirm if the
system supports this 1920 x 1200 reduced blanking mode.
If your digital graphics card provides the 1920 x 1200
digital resolution using a single DVI connector, then the
reduced blanking mode is supported.
