Display Settings 3.x

This page is related to the Control Center interface present on HMP200, HMP130, and HMP100. See also Display and audio settings on HMP350 and HMP300 page.

Description

The "Display Settings" page of HMP Control Center contains different tabs that allows configuring different settings related to:

• display output,
• power saving,
• interactivity,
• splash screen images,
• audio & signals.

Display tab

This tab groups several options related to HMP video output signal mode configuration. Note that the display options change depending of the selected configuration type: "Simple", "Advanced" and "Custom".

Simple configuration

Display tab - Configuration: Simple

Allows selecting the HMP video output signal mode from a fixed number of common video modes, divided in three categories:

• TV Screen (16:9)

  HMP130 / HMP100 : 480p @ 60Hz, 720p @ 50 / 60Hz.

  HMP200 : 720p @ 50 / 60Hz, 1080p @ 50 / 60Hz.

• Computer Monitor (4:3)

  HMP130 / HMP100 : VGA 640x480, SVGA 800x600, XGA 1024x768.

  HMP200 : VGA 640x480, XGA 1024x768, SXGA+ 1400x1050.

• Wide Computer Monitor (16:10)

  HMP130 / HMP100 : WVGA 768x480, WSVGA 1024x640.

  HMP200 : WXGA 1280x800, WSXGA+ 1680x1050.

In case the resolution selected does not match the aspect ration of your screen, a different aspect ratio can be enforced by enabling the "Force aspect ratio to" option and selecting a different aspect ration between 4:3, 16:9 or 16:10.

Also, the HMP video output signal can be rotated or flipped to match the screen orientation - this is done by selecting a value for the "Screen orientation" option between:

• "Horizontal" (default value),
• "Rotate 90 Right", "Rotate 90 Left", "Rotate 180",
• "Flip Vertical", "Flip Horizontal".

Advanced configuration

Display tab - Configuration: Advanced

Allows selecting the HMP video output signal mode (as resolution@refresh_rate) from either the "Standard modes" set (provided by the HMP) or the "Screen modes" set (provided by the screen).

The aspect ratio of the output signal ("Default aspect ratio") and the orientation ("Screen orientation") can also be configured. See more details above.

The "HDMI display supports underscan" option enables / disables the underscan feature for HDMI connections.

• 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 VGA or DVI.

To save the selected settings, first press the "Check" button (the HMP will verify that the video output signal is valid) and then press the "Apply" button.

Custom configuration

Allows setting custom resolutions for non-standard screens. See the Custom display settings page for more details.

Power Save tab

Control Center - Power Save

This tab groups options related to power management configuration.

Display Power Save

• Enable display power saving

  Enable / disable the power save features of screens connected via VGA or DVI.

• Use fixed schedule for display power

  Enable a basic power on / power off schedule. (See also how to create a custom power saving schedule.)

Device Power Save

• VGA output enable

  Set the detection of a display connected via VGA (this is useful for VGA power saving). Possible values are:

  • Automatic - VGA signal is enabled / disabled depending on the Display Data Channel (DDC) signal. This is the default value.
  • Always On - VGA signal is always sent.
  • Always Off - VGA signal is never sent.

Interactivity tab

 

For HMP400/W, HMP350, and HMP300, see Advanced Applications page.

Interactivity tab

This tab groups several options related to event-triggered interactivity configuration.

Interactivity Settings

• Enable events

  Enable / disable interactive event processing. Default: disabled.

• Maximum rendering latency

  Select the HMP rendering latency value. Default: 1500ms.

• Reduce latency to 60ms when events are received

  Enable / disable interactivity boost. Default: enabled.

Notes:

• By default, the HMP is configured to use the maximum rendering latency (1.5s) with interactivity boost enabled (that means that the latency is lowered to 60ms when events are received). See also how to reduce the rendering latency and when not to reduce the rendering latency.
• If a touchscreen device is used, you might need to calibrate the touchscreen first.
• In case of interactivity problems, you should toggle the "Support large number of USB devices" option from the I/O Automation page and see if that solves the issue.

Touchscreen Calibration

See also MultiTouch support section.

Many touchscreens (or other input devices reporting absolute coordinates) are usually already calibrated and require no further configuration to be used. If you notice that the touchscreen is not working properly, or it's not very accurate, then you should run the touchscreen calibration procedure:

1. Connect the HID-compliant touchscreen device to the HMP via the USB port.
2. Open HMP Control Center > Display Settings page and select the Interactivity tab.
3. Ensure that the "Enable events" option is checked, otherwise enable this option and restart the HMP.
4. On the same page, press the "Start Calibration Procedure" button and follow the instructions displayed on the touchscreen.
5. At the end of the calibration procedure, the player computes the calibration offset values.
6. Note the values displayed by the calibration tool and enter them on the Interactivity tab.
7. Press the "Apply" button.

Splash Screen tab

For HMP350 and HMP300 devices, see Splash screen settings page.

Splash Screen tab

This section allows uploading custom splash screen images to be used by the player during booting, shutting down or firmware update sequences.

• JPEG or PNG images should be used, no larger than 1 MB in size.
• The recommended image resolution is 640x480 pixels, to match the lowest output resolution of the player. Bigger resolutions are also accepted, but since the image is centered without scaling, it might not be displayed entirely (especially in the case of Boot splash screen).
  • For instance, let's say you have set a 1920x1080 px image as boot splash screen and 1080p as display resolution. When the player boots, the display resolution is firstly set to the 640x480 and therefore the splash screen will be a cropped area of 640x480 pixels from the original image (relatively to its center). This will be displayed on the entire screen (probably stretched). Only after the display resolution is set to 1080p, the entire image will be shown.

Note:

Use the "Reset" button to revert to the default splash screen images.

Advanced tab

Advanced tab

This tab groups audio and advanced signal related options.

• Audio

  Activate or deactivate the audio output signal using the "Enable audio output" check-box option.

• HDMI signal

  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. It has an effect only when "HDMI display supports underscan" option is disabled.

  Set the "HDMI link type" between "Automatic" (default value), "HDMI" and "DVI".

• VGA signal

  Activate or deactivate the DC offset support using the "VGA display supports DC offset" check-box option.

  Starting with 2.2.4 firmware, the VGA output in all HMP models has a DC voltage offset in the RGB signals by default. This improves the quality of the black levels and is compatible with the vast majority of displays. If a display or repeater does not support this voltage offset (i.e. the image appears as overexposed), then you need to disable this option.
