This is an issue with your TV settings. By default overscan is on for most TVs and needs to be turned off. This causes the edges around the picture to be cut off and appear small. Since how you turn this off differs for each brand and model TV you will need to post all that information here for people to help you. Or find a guide online that tells you where to find this setting.

The is no way to fix this in game as the devs have commented this is fixed by adjusting the TV settings.
