Hi,

Do you guys have any other ideas to implement the dynamic change
of display resolution?

You may be able to support resolution change by rotating the display
two times.
You rotate the display 90 degrees and then rotate it back, changing
the resolution in the process.
Obviously you should change your driver to support this "trick" (it
should be able to change resolution during rotation (you may add an
extra excape code and do the resolution change using ExtEscape) and
should allocate a video "ram" buffer big enough to hold the highest
resolution you need to support.
Applications may not handle the resolution change gracefully, so you
may have to modify them or implement some mechanism to resize their
window to force an update.


Thanks Valter Minute,

What you mean is to do some modification in the display driver (sa2video.cpp
function DynRotate)?
But if i rotate the screen 90 for the first time and rotate it back, it seem
will end up the original resoultion, or could you give some example?

Thanks...
