What do I need....

Please help, I need a quick fix. I have an old camera (yes we are going to be updating this rig soon) and It is feeding HDMI into a computer and going out to ZOOM and YouTube. I need a tap. I need to be able to monitor this camera BEFORE I send the stream out. Any thoughts?

An hdmi splitter after camera may feed PC and display...

Thanks for that. I was a little concerned about splitting HDMI but for $30 I will give it a go. See if it works. Should be here tomorrow.
