I have Creator 3D in my Ultra 10. I am running it with 1280x1024x67 on my LCD.
I booted Solaris via the serial console then ran ffbconfig to find out all
combination of supported resolution/frequency. That is the only one works on my
LCD. Perhaps, you might want to find out what your hardware is capable of
before you can change your setting.
