Lowest supported resolution in Mac OS 9.2.2
« on: April 06, 2020, 01:58:36 AM »
Is there low limit in graphics resolution in Mac OS 9.2.2?
Example the original Macintosh resolution: 512×342 1-bit (b/w)

Lowest I can get is 640x480 8-bit (256 grayscales)
I have seen 640x480 1-bit at Mac OS 8.1.
I have CRT that support down to 320x200 resolution and it would be nice to test.

Likely, any New World ROM Mac would be 8bit by default, but screen resolutions would be a matter of the graphics cards 'NDRV' and EDID of the display.

Old World Macs with Open Firmware and PCI slots may also be limited to 8bit color/grays.

Village Tronic MP 960 and MPDD Pro specifications says supports 320x256 24-bit colors at 50 Hz. Has somebody those cards to test how less colors can be?

EDIT: Also MP850 and MacMagic Pro (3dfx Voodoo Banshee based cards) support that.
