Specifications 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.
