How can I show a powerpoint presentation on tv without everything on the computer screen showing on the tv? I hope that made sense.?

You should be able to tell your computer to use the video output as extra screen area instead of a copy of the LCD display: "Set up dual monitors on Windows 10" https://support.microsoft.com/en-us/help/4340331/windows-10-set-up-dual-monitors

On the top of your Power Point screen look for and click on "Slide Show." On the far left choose "From The Beginning." advance each expanded slide with the space bar. Press "Esc" to leave.
