#Unusual VESA modes
2 messages in this thread
Is there a VESA driver that supports 360 X 480 or even better, 320 X 240
resolution (256 colors) that will work with the ATI Wonder 24 EXCEL board?
The ATI Board supports 360 x 480 resolution as I discovered when I bought some
educational software for my son, 'Dinosaur Adventure.' I use Autodesk's
Animator Pro and often use 320 X 200 resolution for animations because it's
faster than 640 X 480 and uses less memory–but unfortunately, when I record
this to video, the tops and bottoms of the screen are black bars of empty
video. I can't fill the screen with 200 lines of vertical resoultion. 240
lines fills the screen nicely. So… Help! Where can I find the appropriate
driver?
Thanks!

360×480 and 320×240 aren't VESA modes… they're regular VGA "tweaked" modes,
meaning that some clever programmers figured out a way to reprogram the VGA
into such strange modes as 320×400, 320×480, 320×240, 360×480, etc. To learn
how to do this, look for John Bridges' VGAKIT, which is probably available over
in GRAPHSUP, or a book by Michael Abrash called … well, I forget what it's
called, but it's a collection of his Programmer's Journal graphics columns.
