High Definition (HD) Auto Tune automatically tunes Charter TV customers with HD receivers to the HD version of any channel they select if that channel is available in HD. If a Standard Definition (SD) channel number is selected and there is an HD counterpart available, the receiver will automatically tune to the HD Channel. This includes tuning to an SD channel directly via the Charter remote or by selecting the channel through the interactive guide.
The SD channel numbers within the Interactive Program Guide and Channel Banner are retained, but the station letters and program information are updated to reflect the HD version of the channel.
When HD Auto Tune is enabled on a DVR, all scheduled recordings will record in HD. After scheduling a recording from either an SD or HD channel, you can access the DVR menu and modify the recording to record in SD.
Content recorded in high definition consumes more available hard drive space on your DVR. Consequently, while the visual quality of the content being recorded is improved, you will not be able to record as many hours of content. For information on adding more hard drive space to your DVR click here
Please be sure to check your parental controls to ensure that any program(s) you choose to block is blocked on both the HD and SD versions of the channel. If you currently have an SD channel blocked, the block may not transfer over to the HD channel.
If you have an SD TV connected to an HD receiver and notice that images on your TV do not fill the screen like they used to, you may wish to turn the HD Auto Tune feature OFF.
For information on how to enable and disable HD Auto Tune, select the TV Guide image that matches your On-Screen Guide.
