Xbox One users have a few options when it comes to adjusting their screen size. The first is to adjust the Xbox One’s resolution. This can be done by going to Settings and selecting “Screen Resolution.” Then, select “Width” and “Height” and set the values to what you want. If you want a smaller or larger screen, you can also adjust the “Size” setting. Finally, if you want to change the color of your Xbox One’s screen, you can do this by going to Settings and selecting “Color.”
