Graphical Environments & Desktops • no way to "underscan" video

Here's an interesting one. Please read in entirety before responding, to facilitate only applicable comments.

I have an old 1366 16:9 westinghouse TV driven via hdmi by a legacy GT610 nvidia card (using nvidia drivers, not nouveau)
The monitor has no way to correct for overscanning. D'Oh! I looked at xrandr underscan options but none of them work. I then did notice the nvidia-settings allows for underscanning, but it accomplishes the task by creating a viewport that is smaller than the total X11 dimensions...and this is NOT wayland, so those comments would not be relevant.

Anyway, setting the underscan region does seem to restrict the desktop dimensions and a band can be seen around the edges...However!...

There is always a "however".

The mouse still has full screen range, including off-screen overscanned areas...AND...any app that is put in fullscreen mode (without any desktop decorations) ignored the undercan, and occupies the off-screen area as well. I tried mplayer and mvp with all available video driver options and they all behave the same: overscanning when it is not wanted.

Here's the monitor and screen sections from xorg.conf
Obviously, manual scaling is not a desirable solution because it may be done innefficiently in software instead of by the GPU hardware.

Thoughts?
