HP EliteDisplay S240ml 23.8-in IPS LED Backlit MHL Monitor - Manual (Page 22)

Turning on the monitor
1. Press the power button on the source device to turn it on.
2. Press the capacitive power button on the lower right front of the monitor to turn it on.
NOTE: When the power button is pressed, the other capacitive button icons light up briefly.
CAUTION: Burn-in image damage may occur on monitors that display the same static image on-
screen for 12 or more consecutive hours of non-use. 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.
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 status message is displayed for five seconds. The message
shows which input (HDMI, DisplayPort, VGA, or MHL) 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.
You can change the default source in the OSD by pressing the front panel
Menu button and selecting
Input Control > Default Input.
