HP Desktop PCs, Monitors, and TVs - About HDMI
HDMI (High-Definition Multimedia Interface) connections are typically used for high-definition (HD) digital video and audio. It is available on digital devices such as TVs, set-top boxes, audio/video receivers (AVR), PC graphic cards, DVD playe rs, and other devices.
The following is a summary of the HDMI standard for 1.3:
note:You may find that the Consumer Electronics features provided through HDMI are not supported on your HDMI display device as this requires extra functionality designed into the device.
HDMI exclusively carries digital signals.
One HDMI cable transfers both high-definition video and audio.
Standard and mini connector sizes are available and adapters can be used to connect the two types.
Supports video resolutions of 480p, 720p, 1080i, 1080p/60, NTSC and PAL.
Supports a wide range of multichannel digital audio.
Single-link bandwidth of 340 MHz (10.2 Gigabits per second)
Supports up to 48-bit color depth.
For the latest specifications and more detailed information, see the Official HDMI Website (in English).
HDMI and DVI
HDMI and DVI are capable of transmitting similar image quality. HDMI video is compatible with DVI using an adapter. Audio is not supported through DVI.
Make sure that both the digital device (such as DVD player, AVR system) support HDMI. Connect the digital device to the HDMI connector on the HDTV or monitor using an HDMI cable.

Category 2 HDMI cables support 1080P or higher video definition.
Configure the HDTV and digital device to use HDMI. For specific instructions see (HP WWSG) the HDTV and device documentation.
If you are using an HDMI connection from a DVD player or set-top box, to hear audio through the HDMI cable, you might need to set the audio to PCM or HDMI from the device's on-screen menu system.
If using HDMI from a computer, the HDMI connector is located on the graphics card on the back of the computer. To enable HDMI audio, set the onboard-audio setting in the BIOS to Auto and make sure HDMI audio is selected as the main audio output in Windows Audio Properties from Control Panel. For more information about how to use HDMI with a computer, see Using HDMI Audio with a Desktop Computer.
Picture quality issues: Use an HDMI cable five meters (16 feet) or less in length. Longer distances can result in signal degradation and possible loss in audio and video quality. For longer distances, use a higher quality cable (Category 2) or a signal amplifier.
No picture: Make sure the input source on the display device is set to the proper HDMI connection being used - especially when your TV or monitor has more than one HDMI connector. For example, if your TV is connected to a DVD player using HDMI 2, make sure the DVD player is set to use HDMI in its menu and make sure that the TV's input source is set to HDMI 2.
No audio: Make sure HDMI audio is enabled in the source digital device and the audio connection is plugged into the correct DTV audio out connector.
If you are using a DVI-to-HDMI adapter you must connect separate audio cables from the device that is sending the audio and video signal into another device that is capable of playing audio (this may be the TV or Monitor also used to display video if the device has speakers and separate audio inputs).
If you are trying to send audio through HDMI from a PC, make sure any onboard-audio setting in the BIOS is set to Auto and make sure HDMI audio is selected as the main audio output in the operating system (for example, Windows Audio Properties in Control Panel).
