Hi!

Puppy does not show all of my monitor resolutions.
The monitor has Full HD, but in puppy can be a maximum of 1600x1200 selected .

What should I do so that I can choose to 1920x1080?

Maybe CatDude solution here http://www.murga-linux.com/puppy/viewtopic.php?t=70496 could fix your ATI graphic card configuration. Greetings from Spain
