NY1 Back On Auto HD

Here is a reminder for Time Warner Cable subscribers.

At the height of the storm Sandy, NY1 lost its HD signal for a few hours.

Some viewers might have switched off a new feature called Auto HD in order to watch NY1.

NY1 is back on Auto HD, so viewers should make sure that it is enabled.

To do that, press the settings button on the remote control, go to the High Definition section and make sure the status for Auto HD is "On."

With Auto HD, viewers who have an HD cable box will see NY1 in HD on both Channels 1 and 701.
