I see six variations at http://en.wikipedia.org/wiki/Digital_Visual_Interface but not one is a 9+1 so this is why you can't find such.
In the future you might supply the monitor make and model to save a few posts.
Hi, I just got a new P.C. and the monitor cable is larger than the hookup on the computer. Can I put a male 9+1 DVI into a 24+1 DVI adaptor? I have looked everywhere and can`t find a 9+1. Thank you for any help, I appreciate it!
