Adapting NeXT MegaPixel Color Display N4005 to a Mac

[elemenoh]

I have a NeXT  MegaPixel Color Display (N4005) that I can't get to sync with either a Quadra 950 or PowerMac 7600.

It's paired with this 10-DIP VGA/Mac adapter at the Mac end and this 13W3/VGA adapter at the Monitor end.

I've tried all of the Sync on Green codes in the 10-DIP adapter but none of them have synced properly.

AFAIK, this 21" monitor is Sync on Green, 68HZ, 1280x1024@92 DPI and is basically a repackaged Hitachi/Supermac CM2086A3UX display.

Should it be possible to get this monitor syncing with a Mac? Any ideas of what else I should try?

The problem might be with the 13W3 adapter.  I believe SUN and Apple used different pinouts.  This thread talks about it a bit.  You might be able to still use the adapter by rewiring it.

provided you are trying to drive the above mode, I agree it’s likely your adapter.
