Forget what you have read about this monitor on the net. It uses a resolution of 1280 x 960, NOT 1280 x 1024.
Since it uses syncronization on the green cable instead of on 2 separate cables, an adapter is needed. I use the 0215-PCS PC Sync Adapter from Griffin Technology. It costs $30, and gives an excellent signal.
Spec: A1097C is a monosync monitor from Hewlett packard. It is not adjustable, but is made for one single mode only, which is 1280 x 960, at 72 Hz, a perfect 4:3 monitor. Sync on green.
This is what it looks like. There are 3 BNC connectors on the back, so
synchronization has to be on the green wire. There are rumours that
there are variants with 5 connectors. (According to
Dusan Jankovic
it is possible to adjust this monitor for
lots of other resolutions by using a screwdriver on the hidden
controls, marked with yellow on the picture. There are markings on the
metal inside.)
