HDMI (High Definition Multimedia Interface) is an audio/video device connection standard. It replaces the old connection methods such as hybrid port or S-video. HDMI transmits digital signals and can process both audio and video signals. HDMI is the simplest way to connect multiple devices without complicated configuration.
Identify and Buy HDMI Cables
Connecting a Home Theater System
- Most new receivers have multiple HDMI input ports, allowing connection to all devices with an HDMI cable, as well as an output port for connecting to a TV.
- If your TV does not support HDMI 1.4, you need to use a separate audio cable to connect the TV and the receiving device. The type of cable for the best sound quality is optical audio cable. Connect an audio optical cable from the output port of the TV to the input port of the receiving device.
- If you watch TV through the cable box, and the box is connected to the receiving device, then you don’t need to worry about ARC because the sound is transmitted from the cable box to the receiving device. ARC is only needed when watching TV online on a TV or wanting to play it on a home audio system. [2] X Research Source
- For example, if the receiver only has two input ports and you have a Roku, PlayStation 4, and DVD player, connect the Roku and PS4 using HDMI and then use the mixed connection for the DVD player. Roku and PS4 will benefit more when connecting HDMI.
- The HDMI connector is only plugged in one way, so don’t try to push the connector.
- Since everything is connected via HDMI, sound from other devices will be output from the speakers of the receiving device.
- Most devices should be auto-configured when an HDMI connection is detected, although you’ll need to tweak it a bit to fit a particular device.
- If the number of devices is more than the number of input ports on the TV, you need to buy an HDMI adapter to increase the number of HDMI ports.
- HDMI-CEC has different names depending on the manufacturer, for example Anynet+ (Samsung), Aquo Link (Sharp), Regza Link (Toshiba), SimpLink (LG), etc. Read the user manual for more information.
Connect the computer to the TV
- If your computer doesn’t have an HDMI port but supports a DVI or DisplayPort port, you can purchase an adapter that allows an HDMI cable to be connected. If converting from DVI to HDMI, you need to use a separate audio cable because DVI does not support audio signal transmission.
- You can buy a USB to HDMI adapter for computers that don’t have an HDMI port.
- You can set the TV as the primary display device, the computer screen will turn off and the picture will be displayed only on the TV.
- You can mirror the display so that the two screens play the same content.
- You can extend your desktop by projecting content onto a large TV screen. This will give you more space when working with multiple windows and documents.
- See the instructions for how to configure two computer monitors.

Advice
- You can connect two HDMI cables together using an HDMI Female-to-Female adapter. Because the HDMI signal is digital, you don’t have to choose an expensive connector or cable length as long as it’s less than 1 meter.
Warning
- Twisting, tugging, or stapling the HDMI cable can damage the cable, so use it with care.
