So I have read the various man pages (starting from plan9.ini that only
sets environment values) to vga.
If I understand correctly, the vesa adjusting is only done if the
monitor variable is set to 'vesa', value that do not appear in the
database.
Previously, I have used other values for monitor, trying to match "more"
the monitor capacities. This ended up using vga.
With 'vesa', there is a setting done that is visibly "sent" to the
monitor by the video card (the monitor starts self-adjusting) and the
problem disappears. I have then set vgasize to the maximum value
reported by the VESA modes of the Radeon video card, and what is
announced to be supported by the monitor (the diverse informations
gathered from "aux/vga -p" could allow to add some entries to the video
database).
So, lesson: with a modern monitor, set monitor='vesa' to let the
software/video_card/monitor adjust themselves accordingly.
