Heres a question to the net that I think might clear things up some: I was fiddling around opening screens and stuff the other day, and decided to try changing the definition of the screen size to *MUCH* bigger than the physical screen. I found that I could then draw shapes that would go off the screen in that direction. (And not whomp on some poor unsuspectiong memory list ;) It was even drawing points on the physical screen PAST the normal 620. So heres the question. Suppose you had a RGB monitor that actaully was, say 1048*400. Could you open a screen 1048*400 and NOT be in interlace mode? If you could, I think this would lead to the following change in 1.4: A change to prefenreces that defines the physical size of your screen for non-interlace and interlace mode An easy way (defaults in OpenScreen?) to get to these values when you open a screen. Then again, I could be totaly dead in the water! Could someone fill me in on this stuff. Thanks,. Stuart STanley STU00@UMNACVX

Just because the monitor is capable of displaying an image that's 1048x400 doesn't mean that the Amiga can generate one. The limitation on horizontal resolution is the speed at which pixels are displayed. The Amiga displays 70ns pixels in hires and 140ns pixels in lores. This is what determines the resolution of the displayed image and won't change unless hardware in the Amiga changes (e.g. ECS).
