The Sony Trinitron "should" work. You may have a Sun adapter. If it's truly a "sync-on-green" monitor, you should only need the color (coax) connections to make it work. As I suggested before, you might want to connect up a pc running terminal emulation (vt100) on a serial port to the serial port in the Indy. That way you can login as root, run setmon to set the resolution and frequency to something compatible with your monitor (typically 1024x768 at 60Hz). When you finally get it running you can try 70Hz or 75Hz. Lyle On Saturday 08 November 2003 08:22, Owen Marshall wrote: -- Lyle Bickley Bickley Consulting West Inc.
