Well so I solved the TV black bar issue:
I downloaded and run the Intel Graphics Command Center (I guess the equivalent
of the Nvidia Control Center for GTX cards) and I was able to select the TV and
there was a Scale option for it that had "Maintain Aspect Ratio" selected and
when I switched it to "Maintain Display Scaling" it seemed to reset the image,
and then the 1920x1080 image filled the screen and the black bars disappeared!
I switched it back to Maintain Aspect Ratio to test it, and it still stayed
full screen, so I guess whatever thing had happened to mess it up is gone now?
So weird...
Still doesn’t help with the Zoom/Discord lag, but I'm going to try your
suggestion next Jamie-thanks!
So no one has used one of those external Thunderbolt (since I have USB4.0 Gen
3x2, I figure that's the same as Thunderbolt 3 right?) external enclosures with
a discrete graphics card and can report back on how well it works...?

Have you tried forcing Zoom and Discord to not use graphics acceleration for
video? I've seen that make a difference with Teams and older Intel Graphics in
my Surface Book 2 (higher CPU utilization, but more stable overall was the
result). If the problem is just that you have the screens connected then this
isn't it, but I've found the acceleration to not be ideal on the SB2 depending
on the client app.
You should be able to use the Intel Graphics Engine tools to add custom
resolutions to help with the Samsung TV. I do that on my Surface Book with its
3240x2160 screen to cut the resolution down so I can use those resolutions with
games. The result is that the Geforce 1060 can much more easily keep up when
compared to native resolution as it's pumping
1/4 the pixels.
