HP Pavilion 23-a000 User Manual

3 Setting up additional features
Using an HDMI monitor (select models only)
If your computer has a graphics card with an HDMI (High Definition Multimedia
Interface) connector, Hewlett-Packard recommends using a DVI or VGA connector
for a monitor, and using HDMI to connect a TV.
If you use HDMI to connect your monitor, you may need to adjust some settings to
hear sound. Because of this, HP recommends that you connect analog speakers to
the computer if you want to hear sound during the initial setup of the computer.
For optimum viewing, you may need to adjust the resolution setting for the monitor.
NOTE: If you ever need to recover the computer operating system you may need
to activate sound and adjust resolution for the HDMI connector.
IMPORTANT: Your HDMI monitor must be connected to the graphics card
before you activate sound and adjust resolution.
Using the HDMI port controls (select models only)
The right side of your computer may contain an HDMI port and volume control
buttons. Unless a device is plugged into the HDMI port, the volume controls have
no functionality. The HDMI controls are only intended to control the settings of the
device plugged into that port, and do not control any other media devices on the
system.
To use the HDMI port controls, plug a device into the HDMI port. Press the menu
button (the top button displayed). A new on-screen menu displays. Using the +/-
buttons, select brightness, volume, contrast, or color balance.
When a device is plugged into the HDMI port, the volume on the computer is
muted. Pressing the +/- buttons on the side panel does not change the volume of
the computer.
