HP Z23i User Manual

CAUTION: Burn-in image damage may occur on monitors that display the same static image on
screen for a prolonged period of time.* To avoid burn-in image damage on the monitor screen, you
should always activate a screen saver application or turn off the monitor when it is not in use for a
prolonged period of time. Image retention is a condition that may occur on all LCD screens. Monitors
with a “burned-in image” are not covered under the HP warranty.
* A prolonged period of time is 12 consecutive hours of a static image.
NOTE: If pressing the power button has no effect, the Power Button Lockout feature may be
enabled. To disable this feature, press and hold the monitor power button for 10 seconds.
NOTE: You can disable the power LED in the OSD menu. Press the Menu button on the front of the
monitor, then select Management > Bezel Power LED > Off.
When the monitor is powered on, a Monitor Status message is displayed for five seconds. The
message shows which input (DisplayPort, DVI, or VGA) is the current active signal, the status of the
auto-switch source setting (On or Off; factory default is On), the default source signal (factory default
is DisplayPort), the current preset display resolution, and the recommended preset display resolution.
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: DisplayPort, DVI, 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.
