This wikiHow teaches you how to connect different types of video devices, including computers, cameras, and gaming systems, or any Roku players to your TV's HDMI port.
Even if the device doesn't have an HDMI port, you can usually make the connection using a special cable or adapter. Acquire a cable that fits the ports on both devices. Connect the cable from one device's HDMI port to the other. Use the Source or Input button on the TV to switch to the port. Configure video and audio on the device if needed.

These ports are usually labeled "HDMI. Get the right HDMI cable. The dimensions are Connect one end of the cable to the device. Turn on the device you want to connect to the TV, and then gently insert the matching end of the cable into its HDMI port. You should only be able to insert the HDMI plug into the port in wha direction.
Never force the cable plug into the port since doing so could damage both the cord and the device. Connect the other end of the cable to the TV. Turn on the TV if you haven't already done so, and then connect the cable securely.
You'll usually have to press it a few times until you reach the right port number. Once you reach the correct source, you should see the device's image on the screen.
If you want to mirror the desktop, for example, select Duplicate. If you have a Mac, the screen should automatically be mirrored on the TV. If you need to enter a specific resolution, chose Scaled instead and enter that resolution now. Configure your computer's audio to route through the TV optional. Windows: Right-click the volume icon in the system tray next to the clockselect Sound Settingsand select your computer's default audio device, often called Speakers High Definition Audiomenat the "Choose your output device" menu.
Method 2 of Look for ports labeled "DP" or "DisplayPort". Note that there are different DVI port sizes, so you'll need to make sure you get the right cable. Count the number of pins in your DVI port and compare it to available cables and adapters. Choose the right cable or adapter.
You'll just need to make sure the non-HDMI size matches up exactly with the port on your device. This means you'd need two different types of cables plugged into one adapter. Choose a cord that is slightly longer than necessary to minimize the strain on the cord and both devices. Connect the what does fluttered pulses mean end of the cable to the ehat or adapter.
If you have an HDMI-to- other cable, plug the matching end into that port now. Do not force the plug into the port. It should only fit one way, and if it doesn't fit at all, you may have the wrong type of cable.
If using an adapter for VGA ports, you will likely need to match the color of each adapter plug to the corresponding audio and video ports on your computer. Hook up the audio separately if necessary. If you're not using DisplayPort, you'll usually need to use a separate cable to stream audio to your TV. Alternatively, you can use an audio cable to redirect audio from your input device to a separate nearby wgat of speakers previously hooked up to your TV.

Jan 19, · HDMI ports deal in digital data. And since the demands placed on digital data change much faster than things did in the analog age, HDMI connections and cables keep having to evolve too. So quickly has HDMI had to adapt, in fact, that there a number of different generations of HDMI port are simultaneously playing a key part in today’s AV world. Oct 08, · HDMI stands for High Definition Multimedia Interface. It is used to send HD signals over a single cable. HDMI can be used for transmitting both Author: Tracy V. Wilson. Feb 02, · HDMI cables are the primary way to connect devices to a TV or home theater set-up. HDMI cables can pass video, audio, and limited control signals. Where You'll Find HDMI Cable Connections Devices that may have HDMI connections include.
Several versions of HDMI have been developed and deployed since the initial release of the technology, but all use the same cable and connector. 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 Consumer Electronics Control extensions. Production of consumer HDMI products started in late The HDMI specification defines the protocols, signals, electrical interfaces and mechanical requirements of the standard.
HDMI 1. Video formats with rates below 25 MHz e. Other formats are optional, with HDMI allowing up to 8 channels of uncompressed audio at sample sizes of bit, bit and bit, with sample rates of 32 kHz, The HDMI standard was not designed to pass closed caption data for example, subtitles to the television for decoding.
This limits the caption style even for digital captions to only that decoded at the source prior to HDMI transmission. This also prevents closed captions when transmission over HDMI is required for upconversion. During the Video Data Period, the pixels of an active video line are transmitted. During the Data Island period which occurs during the horizontal and vertical blanking intervals , audio and auxiliary data are transmitted within a series of packets.
Each packet contains four subpackets, and each subpacket is 64 bits in size, including 8 bits of BCH ECC parity data, allowing for each packet to carry up to bits of audio data. Each Data Island Period can contain up to 18 packets. Seven of the 15 packet types described in the HDMI 1. The General Control Packet carries information on AVMUTE which mutes the audio during changes that may cause audio noise and Color Depth which sends the bit depth of the current video stream and is required for deep color.
The Gamut Metadata Packet carries information on the color space being used for the current video stream and is required for xvYCC. CEC also allows for individual CEC-enabled devices to command and control each other without user intervention. Introduced in HDMI 1. No signal conversion is required when an adapter or asymmetric cable is used, so there is no loss of video quality.
Exact capabilities beyond basic compatibility vary. Adapters are generally bi-directional. Intel created the original technology to make sure that digital content followed the guidelines set by the Digital Content Protection group.
Devices called HDCP strippers can remove the HDCP information from the video signal so the video can play on non-HDCP-compliant displays,  though a fair use and non-disclosure form must usually be signed with a registering agency before use. There are five HDMI connector types. Although no maximum length for an HDMI cable is specified, signal attenuation dependent on the cable's construction quality and conducting materials limits usable lengths in practice   and certification is difficult to achieve for lengths beyond 13 m.
As of the HDMI 1. These cables are marked with an anti-counterfeiting authentication label and are defined as: . In conjunction with the HDMI 2. The annual fee is due upon the execution of the Adopter Agreement, and must be paid on the anniversary of this date each year thereafter.
The royalty fee structure is the same for all volumes. The following variable per-unit royalty is device-based and not dependent on number of ports, chips or connectors:. For example, if a cable or IC is sold to an Adopter who then includes it in a television subject to a royalty, then the cable or IC maker would not pay a royalty, and the television manufacturer would pay the royalty on the final product.
If the cable is sold directly to consumers, then the cable would be subject to a royalty. HDMI devices are manufactured to adhere to various versions of the specification, in which each version is given a number or letter, such as 1.
III Each subsequent version of the specification uses the same kind of cable but increases the bandwidth or capabilities of what can be transmitted over the cable. The link architecture is based on DVI, using exactly the same video transmission format but sending audio and other auxiliary data during the blanking intervals of the video stream. Only the Rec. It added the ability for manufacturers to create vendor-specific formats, allowing any arbitrary resolution and refresh rate rather than being limited to a pre-defined list of supported formats.
It also added support for the xvYCC color space, in addition to the Rec. It also changed CEC capacitance limits, and CEC commands for timer control were brought back in an altered form, with audio control commands added. HDMI 2. This enables HDMI 2. Additional features of HDMI 2. Video formats that require more bandwidth than The increase in maximum bandwidth is achieved by increasing both the bitrate of the data channels and the number of channels.
Previous HDMI versions use three data channels each operating at up to 6. The structure of the data has been changed to use a new packet-based format with an embedded clock signal, which allows what was formerly the TMDS clock channel to be used as a fourth data channel instead, increasing the signaling rate across that channel to 12 GHz as well. These changes increase the aggregate bandwidth from This, in combination with the 2. To achieve even higher formats, HDMI 2.
Other features such as audio, 3D, chroma subsampling, or variable refresh rate depend only on the versions of the ports, and are not affected by what type of HDMI cable is used. Products are not required to implement all features of a version to be considered compliant with that version, as most features are optional. For example, displays with HDMI 1. Successive versions of the HDMI Specification continue to add support for additional formats such as 4K resolutions , but the added support is to establish standardized timings to ensure interoperability between products, not to establish which formats are or aren't permitted.
Video formats do not require explicit support from the HDMI Specification in order to be transmitted and displayed. Individual products may have heavier limitations than those listed below, since HDMI devices are not required to support the maximum bandwidth of the HDMI version that they implement. Therefore, it is not guaranteed that a display will support the refresh rates listed in this table, even if the display has the required HDMI version.
The HDMI 1. Blu-ray permits secondary audio decoding, whereby the disc content can tell the player to mix multiple audio sources together before final output.
As of [update] , most consumer camcorders, as well as many digital cameras, are equipped with a mini-HDMI connector type C connector. Although cameras capable of HD video often include an HDMI interface for playback or even live preview , the image processor and the video processor of cameras usable for uncompressed video must be able to deliver the full image resolution at the specified frame rate in real time without any missing frames causing jitter.
December 8, Retrieved September 14, Beginning with the seventh generation of video game consoles , most consoles support HDMI. Samsung has a similar proprietary thirty-pin port for their Galaxy Tab Most new laptops and desktops now have built in HDMI as well.
Cables are available that contain the necessary electronics, but it is important to distinguish these active converter cables from passive HDMI to VGA cables which are typically cheaper as they don't include any electronics. In recent years, DisplayPort connectors have become a common feature of premium  products—displays, desktop computers, and video cards; most of the companies producing DisplayPort equipment are in the computer sector.
DisplayPort uses a self-clocking, micro-packet-based protocol that allows for a variable number of differential LVDS lanes as well as flexible allocation of bandwidth between audio and video, and allows encapsulating multi-channel compressed audio formats in the audio stream. The USB 3. In addition to the features in common with HDMI such as HDCP encrypted uncompressed high-definition video and eight-channel surround sound , MHL also adds the provision of power charging for the mobile device while in use, and also enables the TV remote to control it.
