Every input connection on Sony HDTVs has an assignable label. Assigning input labels to your HDTV connections will make switching inputs a lot faster as you’ll be able to see which input you want to use right away. Depending on the source device you have connected to an input, you could set your label to something like “Cable box,” “Blu-ray player” or “Game console.” If you switched the device you have connected to one of your Sony HDTV’s HDMI ports, reset the HDMI port label and then relabel it.
