I don't think you'll be able to drive a monitor at 1920x1080 using VGA.
You'll have to use something a little more advanced to get more than
about 1280x1024, because VGA was intended for analog displays that were
much smaller. The xrandr command says you're running on a DisplayPort,
which will easily do higher resolutions, but the KVM you're using will
almost certainly downsample whatever it gets.

Also, have another look at the new Modeline you put in. You called it
"1024x1080_60.00" and you're trying to use "1920x1080_60.00", which of
course does not exist. Typos cause troubles :-) The line also looks
wrong to me, as it doesn't have any numbers >= 1920 in it, and it should
if it's specifying a resolution 1920 pixels wide.
