Windows 10: How can I connect my tower to my all in one desktop

If this is not the correct board, please move and inform me.I purchased a new All in One and want to use it as a monitor for my old desktop tower.I've connected the tower to my All in One via HDMI and it is reflected on my All in One but no indication as to where the tower is located on my All in One. Where might I look for it?

We all have flatscreen monitors now, so it shouldn't matter if the machine is desktop or a tower.
