This is a common problem, even with DVI. If the monitor and
video card/driver/whatever disagree about when the blanking
intervals start or end, stuff will be chopped off one side
or top/bottom of the display.
Usually, with 24x80 text, only one character is chopped off
the left side. If the characters are smaller, one can lose
so many that the console is useless.
Using something other than 24x80 as the default before the
system setup is complete is a harmful regression.
