setting display mode to 640x480 x24 bit doesn''t work on some pcs. is it because some graphic cards don''t support this mode ?

Yah, many graphics cards don''t support 24-bit graphics. It''s starting to be supported more and more, but 16bpp is still the norm...

Use 16bpp.
See ya,
Ben

Many cards support 32 instead of 24 bit pics. Try changing the 24 bit to 32 bit by adding a dummy alpha and it will probably work (Though thats more memory usage).

It''s impossible to create an invalid graphics mode if you Enum the video modes first. You''re doing that aren''t you? No? Start.

640x480x24bits is common for a 4megas graphics card. BUT with 3d screen, this may change (because z-w-buffers???).
My Ati support 640x480x24 (direct3d), but in opengl only support 640x480x16.

You''re probably are going to see more 32-bit graphics support in the
next couple years, because that is where it is at. The reason why some
cards jump from 16-bit to 32-bit, is that 24-bit is an odd alignment
(3 bytes) which sucks. 16-bit and 32-bit are even aligned (2 bytes
and 4 bytes), so they work very well with memory operations.
