OK, now that confuses me...
I didn't know there were monitors out there that were actually reduced to a Single Link port....
Actually, my 226BW has a DVI-D Dual Link capable port (at least the pin holes are there, don't know if they actually work), while the delivered cable is only single Link...
Usually DVI-Ports should be that compatible..
Would you mind showing photos of your monitors connector panel?
Also, do you have a 226bw, or 2226bw? As I can't find a 2226bw anywhere (It's a Samsung I suppose?)
