This section describes problems that will not be fixed. Usually, the source of the
problem is beyond the control of NVIDIA.

Using HDMI/DisplayPort Audio with Displays that have a
High Native Resolution
To use HDMI/DisplayPort audio with some displays that have a native resolution higher than 1920x1080, you must set the display to a lower HD resolution.
Some HDMI TVʹs have a native resolution that exceeds the maximum supported HD mode. For example, TVs with a native resolution of 1920x1200 exceed the maximum supported HD mode of 1920x1080.
Applying this native mode results in display overscan which cannot be resized using the NVIDIA Control Panel since the mode is not an HD mode.
To avoid this situation and provide a better user experience, the driver treats certain TVs– such as the Viewsonic VX2835wm and the Westinghouse LVM‐ 37w3–as a DVI monitor when applying the native mode. Because the driver does not treat the TV as an HDMI in this case, the HDMI audio is not used.

Using HDMI/DisplayPort Displays that do not Support Audio
Some HDMI/DisplayPort displays do not support audio, or have issues with current NVIDIA graphics cards.
The NVIDIA driver attempts to identify such displays and automatically disables the audio. For example, the NVIDIA driver disables HMDI audio for all Philips HDMI
TVs, as these have been identified as having issues with current NVIDIA graphics cards.
There may be cases where either the driver disables audio even though there is no problem, or does not disable the audio when in fact the audio does not work. The following sections describe these situations and provides guidance for handling them.

Corrupted video and no audio
The driver has not disabled audio and the display’s audio signal is incompatible with
the graphics card, causing video corruption.
With a different display connected in order to establish video, disable audio for the HDMI display using the NVIDIA Control Panel‐> Change Resolution page. From the connector list, select HDMI‐HDTV (Audio Disabled).
Video but no audio
Check the connector list on the NVIDIA Control Panel‐>Change Resolution page.
• If HDMI‐HDTV (Audio Disabled) is selected and you want to test whether your HDMI audio does, in fact, work, then select HDMI‐HDTV (Audio Enabled) and the driver will prompt you with instructions for testing HDMI audio with the display.
• If HDMI‐HDTV (Audio Enabled) is selected, then the driver has not successfully detected that an incompatible display is connected.
Future drive versions will properly identify such displays and disable audio.
• If there is no HDMI connector option in the NVIDIA Control Panel‐>Change Resolution page, the display does not support audio and has properly reported this to the NVIDIA driver.

Using HDMI/DisplayPort Audio in Dualview or Clone Mode
Configurations

Two Audio-enabled Ports
In a multi‐display configuration where both HDMI/DisplayPort audio ports are enabled, only the primary display will provide the audio.

One Audio-enabled Port
In a multi‐display configuration where only one audio port is enabled, such as when one display is a DVI display, then the HDMI/DisplayPort display can provide the audio whether is it the primary or secondary display.

Flat Panel Scaling Controls are Non-functional for Some TV Modes for Some Displays
The NVIDIA Control Panel flat panel scaling controls on the ʺAdjust Desktop Size & Positionʺ page are not intended to be used for TV modes, and normally the controls are not available for TV or HDTV displays.
However, Microsoft requires that certain TV/HDTV modes be available for all digital displays, including DVI and HDMI, even if they are not HDTV.
While the NVIDIA flat panel scaling controls are available for those displays, they will not be functional for the TV modes that appear in compliance with the Microsoft requierements. The affected modes are as follows:
• 1280x720p @ 50 Hz (16x9)
• 1280x720p @ 59.94 Hz (16x9)
• 1440x480i @ 59.94 Hz (16x9)
• 1440x480i @ 59.94 Hz (4x3)
• 1440x576i @ 50 Hz (16x9)
• 1440x576i @ 50 Hz (4x3)
• 1920x1080i @ 50 Hz (16x9)
• 1920x1080i @ 59.94 Hz (16x9)
• 1920x1080p @ 50 Hz (16x9)
• 1920x1080p @ 59.94 Hz (16x9)
• 640x480p @ 59.94 Hz (4x3)
• 720x480p @ 59.94 Hz (16x9)
• 720x480p @ 59.94 Hz (4x3)
• 720x576p @ 50 Hz (16x9)
• 720x576p @ 50 Hz (4x3)
