I'm going to assume that you're running X 4.0.? since this is presumably
fairly new kit.
I understand that TFT monitors have a fixed resolution - say 1024x768 -
and can't scale to anything else. What's probably happening is that X is
trying to start with a different res so your monitor ignores it. The
solution is to edit /etc/X11/XF86Config-4 (same file without -4 is for X
< 4.0.0) and make the 'Display' things in the 'Screen' section look like
this:
SubSection "Display"
Depth 1
Modes "1024x768"
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
You should probably leave in the other depths, but depth 24 is the one
you're most likely using. At the moment, you probably have some other
res' on the 'Modes' lines - remove all but the one your monitor
supports.
Bingo! The blind leads the way.
