Can't change resolution (currently 640x480)

[JanetBiggar]

Earlier today I did look in display and checked the default and only the 640x480 showed, no other choices regardless of whether I looked in default or underneath that which showed the 640x480 with the little arrow down that suggests options yet no other options existed.

What is GUI? and where do I find it.

I will do the other things you suggested, but may not get a chance till Friday am.

Thanks so much for your suggestions.
