Generic HDMI Display

Input Pins

HDMI AV Input

This pin represents the incoming HDMI audio and video to display. Connect this pin to an HDMI I/O (NV-32-H) component HDMI AV Output pin.

Note: You cannot wire a Generic HDMI Source component directly a Generic HDMI Display component.

Breakaway Channel

When 'Audio Input Pins' is enabled in the Properties, each pin represents one channel of audio from a Q-SYS audio source that replaces the audio from the HDMI signal. This is useful, for example, if you want to display HDMI video but use the display's speakers (or connected speaker bar) to play independent audio, such as a music track, PA system pages, etc.

Output Pins

This component has no output pins.

Schematic Examples

Note: For more NV-32-H schematic examples showing different configurations for encoders, decoders, and sources, see HDMI I/O (NV-32-H) and Generic HDMI Source.

Properties

Name

The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Location

User-defined name that groups the component with other components in the same physical location, or in the same organizational scheme.

Audio Source

This property determines what audio, if any, is sent to the display. To see this property, you must wire the Generic HDMI Display component to an HDMI I/O component's HDMI Output pin. There are three choices:

Selected Source: (Default) Audio from the selected AV source is sent to the display over HDMI. In this mode, audio is not processed in the Q-SYS Core's DSP, so no network audio channels are consumed. This option exposes HDMI Audio controls for a maximum of 8 audio channels, depending on the audio capability reported by the display's EDID, as specified in the Generic HDMI Source properties.
None: No audio is sent to the display over HDMI.
Audio Input Pins: Audio from the selected AV source is removed and replaced with audio connected to the Breakaway Channel pins. This audio is routed through the Q-SYS Core's DSP, consuming network audio channels. This option exposes HDMI Audio controls for the number of configured Audio Channels in the component properties, up to 8 maximum, depending on the audio capability reported by the display's EDID.

Audio Channels

When the Audio Source property is set to 'Audio Input Pins', this determines the number of audio input pins and corresponding audio controls to show. You can specify 0, or 2 to 8. The default is '2'.

Note: To avoid a "Compromised" status for the Generic HDMI Display, ensure that the number of Audio Channels matches what is supported in the display's EDID.

Is Required

When set to 'Yes', and the device is not found on the network, the device is reported as 'Missing', which is an error condition. When set to 'No' (default), and the device is not found on the network, the device is reported as 'Not Present', which is not an error condition.

Controls

Note: You must wire the display's HDMI AV Input pin to a NV-32-H HDMI AV Output pin to expose the display controls.

Status

Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:

OK: The device is functioning normally.
Initializing: The device is in the process of a firmware or configuration update, or the design is starting.
Compromised: The device is functioning, but a non-fatal problem exists.
Missing: The device cannot be discovered.
Fault: The device is malfunctioning or is not properly configured.
Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being pushed to the Core and before it has started running.
Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.

EDID

Name, Serial Number, Audio Channels

These values are obtained from the display's EDID, with the Audio Channels value being the maximum number of PCM audio channels supported by the display. If the EDID cannot be read, these fields are blank.

Save EDID to Core

Click this button to save the display's EDID file to the EDID folder on the Q-SYS Core. Each button press adds an incrementing filename number suffix – for example, VA2246SERIES.bin, VA2246SERIES(1).bin, VA2246SERIES(2).bin.

Tip: Use Q-SYS Core Manager to manage EDID files - see Video Endpoints.

HDMI AV Input

Connected (HPD)

This LED glows green if the HDMI Hot-Plug Detect (HPD) signal is active, indicating that the display is connected to the NV-32-H.

HDMI Enable

This enables or disables the NV-32-H HDMI output, with a default of 'Enabled'. Setting this control to 'Disabled' produces the same result as unplugging the HDMI cable to the display:

HDMI output is immediately turned off.
No idle screen is shown.
Selecting an HDMI source does not turn on the HDMI output.

Idle Mode

Determine what content is displayed, if any, after a pre-set amount of time has elapsed – for example, between meetings.

Source Content: Select whether to show the Idle Screen (default), Black Video, or Graphic 1-3. Upload custom idle screen and graphic content using Q-SYS Core Manager - see Video Endpoints.
Timer: Select the amount of time to elapse (with no HDMI signal and black screen) before triggering display of Source Content: 15s, 30s (default), 60s, 120s.
Trigger: Click this button to force Idle Mode to begin immediately.

Sleep Mode

Determine what content is displayed, if any, after a pre-set amount of time has elapsed in Idle Mode – for example, at the end of the business day.

Source Content: Select whether to Disable HDMI (default), or show Black Video, the Idle Screen, or Graphic 1-3. Upload custom idle screen and graphic content using Q-SYS Core Manager - see Video Endpoints.
Timer: Select the amount of time to elapse in Idle Mode before triggering Sleep Mode: 1s, 5s, 30s, 1m, 10m (default), 30m, 60m, 8hr.
Trigger: Click this button to force Sleep Mode to begin immediately.

Video Format, Status

This control sets the HDMI video format (resolution and frame rate) the NV-32-H sends to the display. This setting is independent of the source – the format you select is applicable to both network AV and local HDMI sources connected to the NV-32-H. Incoming source signals are scaled to match the output Video Format. The status text box indicates the current format being sent to the display.

Auto: (Default) The display uses the highest priority format (as communicated in the display's EDID) that is compatible with the NV-32-H HDMI output. If a display's EDID cannot be read, the universally-supported format of 640x480p60 is used.
Tip: Auto mode negotiates the highest resolution of the display and scales any source up to that format. For example, a 1080p60 source and a 4K60 source would produce the same output resolution. This mode eliminates the need to save a display's EDID file and apply it to sources.
Forced (listed format): To force a particular resolution (horizontal size and vertical size) and frame rate for the display, select a format in the list. The list includes only formats that the NV-32-H supports.
- An asterisk (*) indicates a format included within the display's EDID. These are the resolutions that the display prefers.
- The (preferred) label indicates the display's preferred format. For example – 1920x1080p60 (preferred)*
Tip: When you select (force) an output format, corrupt source EDID files are less likely to cause issues.

HDCP Mode, Status

HDCP authenticates and encrypts content, and is required by many HDMI sources. This control defines how HDCP authentication is negotiated with the connected display. The status text box indicates the HDMI output's current HDCP status.

Auto: (Default) HDCP is enabled on the HDMI output connected to the display whenever HDCP-protected source content is detected. There is a time delay of a few seconds when changing AV sources while the negotiation process determines if HDCP encryption is required by the source.
Off: No HDCP authentication or encryption is attempted. Protected content cannot be displayed. If you attempt to display protected content, you will see an HDCP error screen.

HDCP Encryption

This LED glows green whenever the HDMI content being received by the display is protected by HDCP.

HDMI or DVI, Status

Use this control to override the type of display reported in the display's EDID. The status text box indicates the mode currently driving the display.

Auto: (Default) The display type (HDMI or DVI) is determined by the display's EDID.
Force DVI: This option disables embedded audio and InfoFrames (metadata about the video signal). You can use this option to troubleshoot video issues with the connected display. Because embedded audio is not passed to the display, the audio controls are disabled.

Color Format

Use this control to override the color format as reported in the display's EDID. This can be useful for correcting displays with incorrect color format processing. The status text box indicates the current color format being sent to the display.

Auto: (Default) The display's EDID and video resolution determine the color mode and data range (quantization).
Force YCbCr 444: Change the output format to YCbCr 4:4:4.
Force RGB: Change the output format to RGB and use the HDMI defaults for setting the pixel data range (quantization).
Force RGB Full Range: Change the output format to RGB data and full-range (0-255) component pixel values.
Force RGB Limited Range: Change the output format to RGB data and limited-range (16-235) component pixel values.

Note: When the HDMI-DVI Status control is 'DVI' (either forced or auto-detected), the Color Format control is preset to 'Auto' and grayed out. (The output color format cannot be changed for DVI displays.)

Color Format Status

Indicates the color format being output to the display, RGB or YCbCr. Each color format has additional detected parameters:

RGB indicates the supported pixel component quantization range, Full or Limited. For example: "RGB Limited"
YCbCr indicates the supported color sub-sampling mode (444 or 422), color space (BT.601 or BT.709), and pixel component quantization range (Full or Limited). For example: "YCbCr 444 BT.709 Limited"

HDMI Audio

The HDMI Audio section of the control panel only appears when the Audio Source property is set to 'Selected Source' or 'Audio Input Pins':

When set to 'Selected Source' (the default setting), eight channels are shown. However, only the number of supported channels (as dictated by the display's EDID) are active and the rest are disabled.
When set to 'Audio Input Pins', the number of Audio Channels (as configured in Properties) determines how many channels are shown.

Note: If an HDMI source has fewer audio channels than the display supports, the display only receives the number of channels sent by the source.

Valid

LED glows green when the embedded audio for a channel is currently being sent to the display.

Peak Input Level (dBFS)

Indicates the peak level of the audio signal for each channel, from -120 to 20 dBFS.

Clip

LED indicates if the audio signal is being clipped.

Clip Hold

Click to hold the clip indication until you manually clear it.

Invert

Click to invert the polarity of the digital audio signal sent to the display.

Mute

Click to mute the digital audio signal sent to the display.

Gain

Click to adjust the gain of the audio signal sent to the display, from -100 dB to 20 dB (default is 0).
