Xbox one overscan option.

Thats my tv. Does that overscan option effect games?

It shouldn't. Have a look at what I have said below! (Taken from Wikipedia)

Today's displays, being driven by digital signals (such as DVI, HDMI and DisplayPort), and based on newer fixed-pixel digital
flat panel technology (such as liquid
crystal displays), can safely assume that all pixels are visible to the viewer. On digital displays driven from a digital signal, therefore, no adjustment is necessary because all pixels in the signal
are unequivocally mapped to physical pixels on the display

Should i turn off the overscan option in the video settings on the Xbox one because there is a app that some stuff that i cant see on the app when overscan is enabled. I disable it I can see the entire screen but they recommend you to leave it enabled
so do i disable it or no?

I recommend turning it off. Overscan is mainly used for bigger TVs like 45"(ish)+

On my Xbox, I have overscan turned off and everything is fine.

I hope this helped!

Having taken a good look around there doesn't actually appear to be a solution as the Vizio just doesn't have the options to correctly disable overscan. Sorry but it's either a case of live with the overscan using HDMI, use the DVI option on the Xbox and
use the optical audio cable connected to an external audio device or purchase a newer tv that will cope better with the Xbox One's lack of any settings regarding overscan.
