- Bert's answer is right. Just something "close enough" to the resolution and
- refresh you want and it should work, provided your syncs and blanking also
- are within tolerances. If you have a real multisync (and not just multiple
- fixed frequencies) it's pretty easy to pick something "close enough." Those
- people with fixed frequency monitors have to be more careful and look at the
- specs a bit more before customizing.

- What would you say to 1360x1024 for a good aspect ratio on a 9517? Kind of
- oddball, but I think it looks nicer than 1280x1024. Naturally, this isn't
- an officially supported mode (at least with the 2.0 reference disk -- I'm
- not completely sure if it's on the 2.02 beta disk or not), but I mention this
- as a way of saying that the OS/2 and Windoze drivers should support that kind
- of strange size.
-
- Still, I have to say that I really like being able to change the resolution
- just by editing the file. For example, you can do strange things like an
- 800x600x64k color mode on an 8515 where the screen is just a block in the
- middle of the normal 1024x768 mode for those times when you want more colors
- but have a fixed frequency monitor.
