First, check if screen magnifier is enabled in Settings -> Accessibility as this option needs to be disabled for display scaling to work. If you are using a 2nd generation Amazon Fire Stick, you will not be able to scale the display with the on-screen arrows. This is a known issue. To get around this, you must adjust the TV scale on your TV input settings.
Your TV screen calibration setting may vary by TV model. The setting may be called the following:
* Zoom
* Picture Size
* Aspect Ratio
* Just Fit
* Full / Size 2
* Scale
* Dot by Dot

Click which reset, where in display settings? There is no such function.
When trying to calibrate the screen, I clicked reset and nothing would happen, however when I kept clicking reset I could see the arrows moving and when the arrows were where I wanted I clicked on accept. Hope this helps.
