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."
HDMI ports are clearly labeled “HDMI 1, 2, 3 etc.” on your television. If you are using a universal remote or a remote provided by your cable or satellite television carrier, you will likely have to program the remote to work for your television before use. Refer to your provider’s user guide for instructions regarding how to program the universal remote. Most televisions allow you to rename your HMDI ports according to the type of signal source you connect to the port. For example, if you plug your DVD player into the port labeled “HDMI 1,” you can rename that port “DVD” instead of “HDMI 1” for easier reference when switching between inputs.
Depending on the type of television for which a universal remote is programmed, buttons on a universal remote often perform functions other than those written on the buttons themselves. For example, the input selector for a Panasonic television might be the “AUX” button on a universal remote, while a Samsung television uses the “Source” button on the same remote to switch inputs. Refer to your satellite or cable provider’s user guide for a diagram of button functions corresponding to your brand of television.
