JWR:ADKM: Thanks JWR. After I wrote my message I found a few via Google - at incredible prices considering they're $4.70 on Amazon - but they won't ship to NZ.
Is DVI-HDMI just a straight cable? I know DVI out to HDMI in is, but not sure about the other way around.
If it is I could use another monitor. But are any changes to raspberry's config.txt required ?
Usually, you use standard a HDMI-HDMI cable and purchase the HDMI-DVI adapter. It's a simple and small adapter e.g. http://www.wavetech.co.nz/HDMI-DVI-1.html
I guess you could also buy a HDMI-DVI cable instead.
If you use an HDMI-DVI adapter, then you don't need to change anything in the Raspberry PI setup. It just worked for me.
Actually, this is the adapter I bought http://www.darkstar.co.nz/argent-hdmi-to-dvi-adapter.html
The two shops are right next to each other here in Christchurch. Wavetech sell the Raspberry PI and accessories. Darkstar sell a lot of network type stuff.
