Correct. The Amiga side of the cable is 23-pin.

I know I'm late to all this... but just know that your 1084 monitor can be used for both 40-column video (C64/C128) and 80-column video (C128).
Hopefully you can find the right cable(s) from prior posts of forum members... but if in doubt, just ask... we'll answer!
We are all here to help, if we can. I actually use a 1080, which is similar to the 1084. The 1084 usually has stereo sound, but I have better luck using the 1080 (they just say Amiga on the front of the monitor) living longer, without any problems. I have found that the 1084 can have problems with the on/off switch - they are actually famous for this problem - and they can have internal troubles too. Right now I use the 1080 with my C-128 in both 40 & 80 column modes. I know there are better options, but this works, so I can use the 128.
