Its cuz setdisplay sends the ioctl to the wrong device.  It should be

setdisplay -d /dev/tty

to send it to the current tty or ttyv<n> to change a specific one.

If you do that then the mode will be changed for that terminal.  There
used to be a -a switch to change all of them but it seems to have been
omitted in later versions.
