Part 1. Why Is My TV/PC Not Showing Full Screen?

If you are trying screen mirroring, you will obviously ask yourself this question. When screen mirroring a phone to a TV, a TV screen doesn't show a full screen. Well, it is simple. It is because of the aspect size and ratio of the device you are mirroring and the TV.

A typical phone is portrait with a larger height and smaller width. On the contrary, a television has a quite different shape. Televisions are wider, which isn't the case with a phone. This will be a challenge when screen mirroring full screen because the devices are different in size. These devices have different aspect ratios: how high a screen is compared to the width.

When the aspect ratio isn't equal, the projected image will appear strange. There will be two scenarios here:

  • You may see only part of screen; the TV's shape will cut the rest.
  • There will be a full screen yes, but with black boxes all round filling the space.

Such problems are frustrating. Luckily, you can easily fix them. Read on to know how.
