High-definition televisions use high-definition multimedia interface (HDMI) connections to transfer a signal between the television and a signal source such as a digital cable box, DVD player or gaming system. Most high-definition televisions have multiple HDMI ports for connecting several devices at once. You can access all HDMI devices connected to your television with either the television's remote control or a universal remote.
Connect all HDMI-compatible devices to separate HDMI ports on your television and turn on the power to each device. Ensure that the batteries in your remote control are functioning by turning on the television with the remote. If the television is plugged in to a power outlet and does not turn on with the remote, replace the batteries in the remote.

Press the "Input" or "Source" button on your remote control. The television will display the name of the input port that is providing the signal. Continue pressing the "Input" or "Source" button until the television display changes from "HDMI 1" to "HDMI 2."
If your remote does not have an "Input" or "Source" button, press the "Menu" button on the remote to access your television's main control menu. From the main menu, use the arrow buttons on your remote to scroll to the option labeled "Input" or "Source." Select that option and scroll through the available inputs until you reach "HDMI 2."
