Using Auto-Sleep Mode Your monitor has an energy-saving feature called Auto-Sleep Mode, a reduced power state. This section describes how to activate or adjust Auto-Sleep Mode on your monitor. When Auto-Sleep Mode is enabled, which it is by default, the monitor enters a reduced power state when the computer signals low power mode (absence of either horizontal or vertical sync signal). Upon entering this reduced power state (Auto-Sleep mode), the monitor screen is blanked, the backlight turns off, and the power light turns amber. The monitor draws less than 0.5 W of power when in this reduced power state. The monitor wakes from Auto-Sleep mode when the computer sends an active signal to the monitor (for example, when you activate the mouse or keyboard). To disable Auto-Sleep Mode in the OSD: 1. Press the Menu button to open the OSD, or press the center of the Joypad to open the OSD. 2. In the OSD, select Power. 3. Select Auto-Sleep Mode, and then select Off. Ambient light sensor (select products only) Select monitors include an ambient light sensor that adjusts the brightness based on the ambient lighting conditions in your environment. You can turn the ambient light sensor on or off in OSD under the Brightness menu or from HP Display Center. For more information about the ambient light sensor, see Front components on page 4. NOTE: If you adjust any of the following monitor settings while the ambient light sensor is on, the ambient light sensor function automatically turns off. ● Ambient light sensor settings are also turned off if you manually adjust the brightness. ● Dynamic Contrast - When ALS is on, Dynamic Contrast is turned off and disabled. You cannot turn Dynamic Contrast on unless you manually turn off ALS. When the ambient light sensor turns off, you must use the manual brightness controls to adjust brightness. DisplayPort multistreaming over USB Type-C (select products only) If you are using USB Type-C as the primary video input source, you can multistream to other DisplayPort monitors connected in a daisy-chain configuration. You can connect to a second monitor in this configuration if the graphics card in your computer supports this configuration. The number of monitors you can connect through DisplayPort multistreaming depends on a number of factors, including the resolutions and scan rates used for each monitor and the capabilities of your GPU or embedded graphics system. If you have purchased a new graphics card for your computer, check the manual that came with your graphics card for further information about its capabilities. 1. Be sure that USB Type-C is your primary video input. 32 Chapter 2 Using the monitor

Using Auto-Sleep Mode
Your monitor has an energy-saving feature called Auto-Sleep Mode, a reduced power state. This section
describes how to activate or adjust Auto-Sleep Mode on your monitor.
When Auto-Sleep Mode is enabled, which it is by default, the monitor enters a reduced power state when
the computer signals low power mode (absence of either horizontal or vertical sync signal).
Upon entering this reduced power state (Auto-Sleep mode), the monitor screen is blanked, the backlight
turns off, and the power light turns amber. The monitor draws less than 0.5 W of power when in this
reduced power state. The monitor wakes from Auto-Sleep mode when the computer sends an active
signal to the monitor (for example, when you activate the mouse or keyboard).
To disable Auto-Sleep Mode in the OSD:
1.
Press the
Menu
button to open the OSD, or press the center of the Joypad to open the OSD.
2.
In the OSD, select
Power
.
3.
Select
Auto-Sleep Mode
, and then select
Off
.
Ambient light sensor (select products only)
Select monitors include an ambient light sensor that adjusts the brightness based on the ambient
lighting conditions in your environment. You can turn the ambient light sensor on or off in OSD under the
Brightness
menu or from HP Display Center.
For more information about the ambient light sensor, see
Front components
on page

.
NOTE:
If you adjust any of the following monitor settings while the ambient light sensor is on, the
ambient light sensor function automatically turns off.
●
Ambient light sensor settings are also turned off if you manually adjust the brightness.
●
Dynamic Contrast - When ALS is on, Dynamic Contrast is turned off and disabled. You cannot turn
Dynamic Contrast on unless you manually turn off ALS. When the ambient light sensor turns off,
you must use the manual brightness controls to adjust brightness.
DisplayPort multistreaming over USB Type-C (select products
only)
If you are using USB Type-C as the primary video input source, you can multistream to other DisplayPort
monitors connected in a daisy-chain configuration. You can connect to a second monitor in this
configuration if the graphics card in your computer supports this configuration.
The number of monitors you can connect through DisplayPort multistreaming depends on a number of
factors, including the resolutions and scan rates used for each monitor and the capabilities of your GPU
or embedded graphics system. If you have purchased a new graphics card for your computer, check the
manual that came with your graphics card for further information about its capabilities.
1.
Be sure that USB Type-C is your primary video input.
