Have you tried holding down "stop-n" when powering up the workstation? It sounds to me like the previous owner had programmed in an unsupported resolution, and the NVRAM needs to be reset.

You could, I imagine, actually update the NVRAM to a supported resolution, but the "stop-n" should set everything back to factory settings, and "just work".

If you've not done it before, the way it works is you hold down the "stop" and "n" keys as you power up the machine and hold them down until you see the lights on the keyboard blink, then you let go of the keys and the machine will restart again. You might notice a message on power-up that the NVRAM has been reset, just above the usual banner reporting various facts about the machine CPU speed & number, RAM installed, MAC address, etc...

HTH,
