The digital age allows our electronic devices to "communicate." Music can be stored on computers and transferred to MP3 players. Video cameras record home movies directly to DVD to watch instantly at home. Computers can be connected directly to flat-screen televisions, allowing us to access the Internet, watch movies, play music and even work from the comfort of our couches. eMachines, a brand of consumer personal computers, can be connected directly to flat-screen televisions using an HDMI cable.
Connect an HDMI cable to the corresponding port on your eMachine. Most eMachines built after 2008 come standard with an HDMI port allowing for easy connectivity with flat-screen televisions that are HDMI compatible. If you have an eMachine without an HDMI port, but a television with one, purchase an HDMI to display port adaptor. The display port is a standard, 15-pin connector that links an eMachine with a monitor. Plug the adaptor into the display port, and connect the HDMI cable.
Connect the HDMI cable to the HDMI port on your television. Almost all high-definition televisions will have an HDMI port located on the side or back panel of the television. If your television does not have an HDMI port, buy an adaptor. These adaptors connect your television's standard AV ports (red, yellow and white) to a converter box that has an HDMI port.
Select the "Menu" on your television, and navigate to the "Audio/Visual" heading. Select the display setting that says HDMI. This turns your television into a monitor for your eMachine. If you have to use an AV to HDMI adaptor for your flat-screen, change your AV setting to the output that you are using to connect the adaptor.
Add a wireless keyboard and mouse to your eMachine to provide some space between yourself and the television.
Computers and CRT televisions have low compatibility because of connectivity and screen resolution issues.
