Overview
Changing the screen resolution at the OpenBoot
ok
prompt enables you to view
console boot messages and the DT login screen. If a type of monitor is used where
the EDID auto-detect is not preset at the

prompt, console boot messages and
DT login screen will not display. In this case, set screen resolutions using
fbconfig
or the GUI method, which displays console boot messages and the DT login screen
(see
