nec muliisync v520 on a1200?

[nahoo7]

gday i have an nec multisync v520 monitor and a 23 to 15 pin adaptor can i use these on my a1200.
I tried it but the screen stayed blank ,it works fine on my a2000 and flicker fixer and can sync to 31k so what do i set in preferences to get it to show on screen or do I need a scandoubler instead of the pin adaptor thanks.

hi I searched for the specs and it only goes down to 31khz so it cant show early boot screens but shouldnt it work on a workbench screen?Ihave an nec multisync c500 or did have because the colors have gone  and another multisync that displays 30 to 48 horizontal khz but alas the brightness adjustment wont work everything is dark.
Ijust cant understand if the new one can sync to 31khz it wont work at all so maybe it shouldnt be branded as a multisync monitor.
