setting is On), 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.
HP watermark and image retention policy
Some monitors are designed with In-Plane Switching (IPS) display technology, which provides ultrawide
viewing angles and advanced image quality. Though suitable for many applications, this panel technology is
not suitable for static, stationary, or xed images for long periods of time, unless you use screen savers.
Applications with static images can include camera surveillance, video games, marketing logos, and
templates. Static images can cause image retention damage that could look like stains or watermarks on
the monitor's screen.
Image retention damage on monitors that are in use 24 hours per day is not covered under the HP warranty.
To avoid image retention damage, always turn o the monitor when it is not in use, or use the power
management setting, if supported on your computer, to turn o the monitor when the computer is idle.
