HDMI, or High Definition Media Interface, is fast replacing RCA, DVI, Component and other video interfaces as the industry standard. Unlike other video cable interfaces that require separate connections for audio and video signals, HDMI streamlines both signals over a single USB-like cable. Many higher-end laptops ship with HDMI ports that you can use to stream video from the notebook to many modern televisions. Using an HDMI connection allows you to make quick work of displaying your laptop display on a large, external TV.
Exit all programs and log out of Windows. Shut down the laptop and disconnect the AC power adapter. Turn off the TV as well.
Connect the HDMI cable to the large USB-type HDMI port on the rear or side of the laptop. The ends of the HDMI cable are the same; so, it does not matter which end you connect to the laptop.
Connect the other end of the cable to an empty HDMI port on the TV. When connecting the cable to the TV, locate the input label or name for that port. For instance, the port might have label or port name "Input 1" or "HDMI 1."
Power on the TV and use the remote control to select the "Input" or "Source" that matches the port name used to connect the HDMI cable. In most cases, you simply need to toggle the "Input" or "Source" button on the remote until the port name appears on the TV screen.
Turn on the laptop and wait for it to boot in to Windows. Log in with your username and password if prompted. Windows detects the new TV connection as soon as you log in to Windows. Windows duplicates the display on the laptop and TV screen.
Press the "Windows" and "P" keys at the same time. The Multi-Monitor display options window appears. Click the "Extend" icon in the window. Windows creates a blank desktop screen on the TV.
Use the mouse to drag icons or windows to the laptop display to the blank desktop on the TV. You can also drag windows from the TV to the laptop display. Audio from Windows applications also plays over the speakers in the TV connected with the HDMI cable.
