Fitting Vcam to TileMap scene?

Hi all,

Like the title says, I am trying to fit my camera to the size of scene that is comprised of a tilemap. The scene itself is in a 16:9 Ratio, and I am attempting to use a Confiner on my VCam to lock the camera to the area I have set up.

Before pressing play, it looks correct! The Camera is confined to the scene and there are no gaps. However, when I press play, gaps appear at the top and bottom. Here is what it looks like:

Why does occur? Is there anyway to just simply make the camera fit the way that I want? I am new to how Unity’s camera’s work so maybe there is something simple I am missing. Here is the settings that I have on my Main Camera and the VCam here:

Any help would be much appreciated!

As an experiment to narrow down the cause, what happens if you disable the PixelPerfect components from the main camera and the vcam?
