Video Settings

Sitting here watching football on my TV and had to switch the refresh rate in my Nvidia Shield to eliminate the micro choppiness (tearing?). That was CBS channel. If I switch to a game on fox next weekend, I'll have to change the video settings as it will have tearing on the settings that work with CBS.

I've not found a setting that has the Shield adjust frame rate on the fly. Is there such a setting? I think I've found a switch on my Amazon Firestick 4k to auto switch, but need to test that more. Anyone else solve this issue?

Thanks.
