Why is Screen Mirroring Not Full Screen On My TV?

Why is screen mirroring not full screen on my TV? This is a common question that many people ask when they’re getting started with screen mirroring, especially when mirroring their iPhone or Android screen onto a TV. However, the answer is actually very simple, and relies on the aspect ratio and size of your device being mirrored and your TV.

To begin with, picture a typical iPhone or Android phone. They’re portrait in size and have a larger height than width. By contrast, your TV has a very different shape: most TVs are wider than they are high, which is the opposite of your iPhone or Android mobile!

Naturally, this poses some difficulties when it comes to screen mirroring in full screen, as you’re dealing with very different devices. This is due to the aspect ratio of your device’s screen; that is to say, how high the screen is compared to its width.

What do we mean by an aspect ratio? Well, an image with an aspect ratio of 1:1 would be perfectly square. However, as this changes, the optimal screen size would also change; this can leave your projected image looking a little strange, and this can leave one of two issues:

1. You can only see part of the screen, as the rest has been cut off by the shape of your TV

2. You can see the full screen, but this is surrounded by black boxes filling the “empty” space

Both of these issues are naturally frustrating when you want to share your screen with your TV; fortunately, though, they can be fixed with a little time and care.

We’ve outlined some of the key reasons why this might be the case for your device as follows, and how you can ensure that your device is displaying the correct screen size when using the screen share functions.
