Raspberry Pi OS • Messing around with "overscan". A blast from the past.

In researching this topic, I came across this old post:

https://forums.raspberrypi.com/viewtopi ... 97#p305797

and this program on Github:

https://github.com/ukscone/set_overscan

I assume that all still works - assuming you are running an older version of Raspbian (Wheezy/Jessie) and on older (pre-Pi4) hardware. I meet both assumptions. In particular, I want to know if this program will allow me to toggle the setting of "disable_overscan" - without rebooting. Does it?

My specific problem is that I have an a Pi running Jessie - been running for almost a decade. It works fine, but I recently had to replace the HDMI TV it was running on. On the old TV, it did fill the entire screen, but on the new TV, I see the proverbial "black border" around the screen. Inspection of /boot/config.txt shows this line:
Now, I want to verify that I understand this correctly. That means to not disable overscan, which means it does overscan, right? So, how does that lead to the presence of the "black border"?

And, if I change it to =1, will that make the border go away?

And, as mentioned above, I would like to do this change w/o rebooting.
