1084s Commodore RGBs cable/ini config

[AntialiasedPixel]

I've got a Commodore 1084s monitor with RGBs din connector input. I've got the parts to make a cable, but just wanted to confirm the details before I start. It looks like the Mister vga out on the io board has a r,g,b, h-sync, v-sync, and ground pins. I can just wire those directly to the din connector on the monitor end? I've seen various cable solutions that use resistors and wanted to be sure I didn't need any for this case. Assuming this is the correct wiring, do I have to set anything specific in the ini for usage on a rgbs monitor?

I made a cable. I do not remember using any resistors. Should be safe.

Thanks! Lots of good info there. So it looks like the mister will output hsync and vsync separately or composite sync on the hsync pin? I've got an oscilliscope so I'll take a look at the signals before hooking it up to my monitor, haven't messed around with video signals all that much, but between Mister, and having to replace a flyback on the 1084s, starting to get a feel for how the video circuitry works.

Also make sure to configure the MiSTer.ini correctly. That was my initial mistake - but you will figure it out. It is not that hard

Success!

Still need to solder up a cable, but having it working with a test setup(monitor is open because I'm waiting on some capacitors to do a re-cap):

For anybody needing the same setup, the wiring I used was:

VGA -> 6 pin din connector (looking into connector on the back of the monitor starting with 1 at top left going around clockwise, 6 in center)
#1 R -> 4
#2 G -> 1
#3 B -> 5
#13 Composite-sync -> 2
any pin 5-10 is ground -> 3

Mister INI settings that seemed to be needed:
composite_sync=1

Good work! - recapping is something I should do as well.

Did this end up working? I have been trying to find some examples of working 1084s MiSTer settings.

I have my 1084 working perfectly with a SCART RGB cable. Big advantages (apart from the great display quality) are that you have knobs for h/v centering and scaling. And because of its boxy design, you can put it on its side as well.
