This page is related to the Control Center interface present on HMP300 and HMP350 devices. See also Display and audio settings on DiVA and, for older models, this page.


The "Display & Audio" page of HMP Control Center allows configuring display and audio related settings, grouped under the following sections:

  • Display
  • Audio
  • Power (added in firmware 4.0.1)
  • Other

These sections are further detailed below.


This section groups several options related to the configuration of the HMP video output signal mode. For the HMP300 model, only the simple configuration detailed below is available, while for the HMP350 model, there are more options available to the user - these options are displayed depending of the selected configuration type: "Simple", "Advanced", or "Custom".

Simple configuration

Display settings for simple configuration

The options included in this section are:

  • Configuration type (HMP350 only)
    Allows changing the configuration type between "Simple", "Advanced", and "Custom".
  • Display settings
    Allows selecting the HMP video output signal mode from a fixed number of common video modes, divided in three categories:
    • TV Screen (16:9): 720p @ 50 / 60Hz, 1080p @ 50 / 60Hz.
    • Computer Monitor (4:3): VGA 640x480, XGA 1024x768, SXGA+ 1400x1050.
    • Wide Computer Monitor (16:10): WXGA 1280x800, WSXGA+ 1680x1050.
  • Screen aspect ration
    Allows changing the screen aspect ratio between 4:3, 16:9, and 16:10. This option will be soon removed.
  • Screen orientation
    Allows rotating or flipping the HMP video output signal to match the screen orientation, by selecting one of the following values: "Horizontal" (default value), "Vertical (CW)", "Vertical (CCW)", "Rotate 180", "Flip Vertical", "Flip Horizontal".

Advanced configuration

This section applies to HMP350.

Display settings for advanced configuration

Upon selecting the "Advanced" configuration type, the "Display settings" option is replaced by "Custom video mode" option, and "HDMI display supports underscan" option is added. The "Screen aspect ration" and "Screen orientation" options are the same as above.

  • Custom video mode
    Allows selecting the HMP video output signal mode as resolution@refresh_rate from the "standard video modes" provided by the HMP.
  • HDMI display supports underscan
    This option enables / disables the underscan feature for HDMI connection.
    The HMP supports underscan for HDMI connection, meaning that all pixels of the image are displayed by the screen, which is standard behavior for computer monitors as opposed to consumer televisions. This feature does not affect connections using DVI.

Custom configuration

Display settings for custom configuration

HMP350 only

The custom configuration is similar to the advanced configuration, the only difference being that the "Custom video mode" option allows setting custom resolutions for non-standard screens, either as a CVT Mode or as a Fixed Mode.

See the Custom display settings page for more details.


Audio settings

The following options can be set:

  • Enable audio output
    Activate or deactivate the audio output signal.
  • Target audio output
    If the audio is enabled, you must select if the audio should be output using HDMI or the Line out.
  • Disable audio when screen is turned off
    You can decide to stop the audio when the screen is turned off.


Added in 4.0.1 firmware release.

Display power saving section

From this section you can manage the display power saving, through the following configuration options:

  • Enable display power management
    Click to toggle the display power management through HDMI-CEC.
    When enabled, the player will automatically turn on the screen when running, unless instructed otherwise through a fixed or custom display power saving schedule.
  • Use fixed schedule for display power
    Click to toggle a fixed schedule for display power saving, through HDMI-CEC (if the former option is enabled and the screen supports it) and / or RS-232. When active, enter the time of the day when the player will turn on / off the monitor and click the "Apply" button.

Note Notes:


Other display settings

The following options can be set:

  • Overscan percentage
    Set the "Overscan percentage" value between 0 and 5. This allows choosing the size (in percentages) of the black frame added by the HMP to compensate for the overscan of the HDMI-connected screen. This cropping is also known as underscan and it has an effect only when "HDMI display supports underscan" option is disabled.
  • HDMI link type
    Can be used to for the HDMI link to use HMDI of DVI signal in case the automatic detection do not work.
