Hey! If you ever came across this monitor, did you have a chance to use its service software? It is a Sony rebrand with a din service port and video through 13w3. Supplied with IBM RS/6000 and maybe also Intellistations it was probably supplied with a service cable and some service software. Sony DAS (DOS version) doesn't have it listed, as it doesn't have it's Sony brother 20sh. But the service port is still there.

Looking for any hints on how to get to the service settings.

Cheers!
