HP (Hewlett-Packard) C4D27AS Computer Monitor User Manual


 
The monitor automatically scans the signal inputs for an active input and uses that input for the display.
If two or more inputs are active, the monitor will display the default input source. If the default source is
not one of the active inputs, then the monitor will display the highest ranking priority input in the
following order: DVI, HDMI, then VGA. You can change the default source in the OSD by pressing the
front panel Menu button and selecting Source Control > Default Source.
HP Watermark and Image Retention Policy
The IPS monitor models are designed with IPS (In-Plane Switching) display technology which provides
ultra-wide viewing angles and advanced image quality. IPS monitors are suitable for a wide variety of
advanced image quality applications. This panel technology, however, is not suitable for applications
that exhibit static, stationary or fixed images for long periods of time without the use of screen savers.
These types of applications may include camera surveillance, video games, marketing logos, and
templates that are displayed on the screen for a prolonged period of time. Static images may cause
image retention damage that could look like stains or watermarks on the monitor's screen.
Monitors in use for 24 hours per day that result in image retention damage are not covered under the
HP warranty. To avoid image retention damage, always turn off the monitor when it is not in use or use
the power management setting, if supported on your system, to turn off the display when the system is
idle.
Locating the Rating Label
The rating label on the monitor provides the product number and serial number. You may need these
numbers when contacting HP about the monitor model. The rating label is located on the bottom of the
monitor.
