Performa plus display only 16 colors?
Posted by: nitsuj99 on 2020-04-25 13:47:18
I’ve read that the Performa plus display can do thousands of colors, but I only see options for 4 and 16 colors. I’d like to get at least 256 colors. Am I missing something? I’ve owned several se/30s, but This is my first color 68k Macintosh.

You probably don't have enough video RAM installed in the computer, or the video RAM in there is not being recognised, or something. 

The Performa Plus display is a 640x480 display.  If you only have 256k of VRAM, there won't be enough room to keep track of 256 colours per pixel.

Which model of Mac do you have?

A stock LC or LC II (or any Performa with a number between 400-430) has 256K VRAM. I don't believe any of the Performa variants came with a 512K VRAM chip (and know for a fact the LC models didn't have it). You'll have to swap out the 256K VRAM chip for a 512K. This will also give you 16-bit color on a 512 x 384 "LC topper" 12" RGB monitor.
