What is the 'Resolution' setting for? Stream+ (CM-7600) DVR+ (CM-7500).

There are a number of TV/Display Video Resolutions. There are also variations of the resolutions with different 'Frame Rate's'. (60fps [frames per second] is the most common. Sometimes content is produced with 30fps or even 24fps.)  For an in-depth explanation, search for "Display Resolutions" on the internet. Wikipedia has a pretty good explanation. 

In the stream+, you can choose  the output resolution for your display. When it is set to 'Auto', the Stream+ will communicate with your display via the HDMI cable. It will automatically choose the highest resolution that the display is capable of processing. This is not always the best resolution. For instance, you may have a 1368 X 720p display, but it is capable of processing 1920 X 1080p signals. If the Stream+ is set to 'Auto', then it will always output all signals at 1080p. The image may actually look a little better if the Stream+ outputs the 720p resolution. 

If you have a 720p display, it will usually look better if you set the Stream+ to '720p @ 60'.

If you have a 1080p display, it will usually look better if you set the Stream+ to 1080P @ 60'.

There is an exception; If you have a 4k TV, the Stream+ will automatically scale all signals to 4k resolution. This is fine for 4k content. However, for most HD programming, if you set the Stream+ to 1080p, it may look better than the 4k setting.

HD antenna TV signals are transmitted at 720p or 1080i resolutions. That is up to the TV station. FOX and ABC are usually transmitted at 720p. CBS and NBC are usually transmitted at 1080i resolution.
