![]() Production of consumer HDMI products started in late 2003. ![]() Other than improved audio and video capacity, performance, resolution and color spaces, newer versions have optional advanced features such as 3D, Ethernet data connection, and CEC extensions. Several versions of HDMI have been developed and deployed since the initial release of the technology, occasionally introducing new connectors with smaller form factors, but all versions still use the same basic pinout and are compatible with all connector types and cables. : §C The Consumer Electronics Control (CEC) capability allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with one handheld remote control device. No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. III CEA-861 signals carried by HDMI are electrically compatible with the CEA-861 signals used by the Digital Visual Interface (DVI). HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed and uncompressed LPCM audio, auxiliary data, and implementations of the VESA EDID. HDMI is a digital replacement for analog video standards. High-Definition Multimedia Interface ( HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HEAC− (HDMI 1.4+, optional, HDMI Ethernet Channel and Audio Return Channel).Maximum resolution limited by available bandwidth LPCM, Dolby Digital, DTS, DVD-Audio, Dolby Digital Plus, Dolby TrueHD, DTS-HD High Resolution Audio, DTS-HD Master Audio, MPCM, DSD, DST, Dolby Atmos, DTS:X ![]() Most adapters come with a micro-USB port for power input.13.9 mm (type A), 10.42 mm (type C), 6.4 mm (type D)Ĥ.45 mm (type A), 2.42 mm (type C), 2.8 mm (type D) You can only use external power if the HDMI to VGA adapter supports it. You can fix this by connecting a USB cable to your PC or external power supply to provide enough power to the built-in active chip. Your HDMI to VGA may not work if the source device outputs low power through HDMI. Q: Why Is My HDMI to VGA Adapter Not Working? These adapters use a built-in chip to convert the digital HDMI output to an analog VGA signal, compatible with most old monitors, TVs, and projectors. You can connect an HDMI source device to a VGA monitor using an active HDMI to VGA adapter. They are ideal for connecting newer laptops and HDMI sources to a display with VGA inputs.These adapters are not bi-directional, so make sure to get a suitable adapter for your needs. They are ideal if you want to connect an old desktop PC with VGA outputs to a monitor, TV, or projector with HDMI inputs.On the other hand, HDMI to VGA adapters converts a digital HDMI input to an analog VGA output. VGA to HDMI adapters converts an analog VGA input to a digital HDMI output. VGA to HDMI adapters are very different from HDMI to VGA adapters. FAQ Q: Is There a Difference Between VGA to HDMI and HDMI to VGA?
