Thank you both! I've never managed to get the LCD working (as of yet). But I did end up writing this nice blog post! Give it a read if interested: https://www.rup12.net/posts/2021/adventures-with-sun-ultra-1-workstation/ Darko

Good evening all, I have a question for the lovely folks of Atari Age. As I have ran out of options here - so I am hopeful someone here can shed some light on the issue I have been struggling with. Backstory: I've gotten my self a 1995 Sun Ultra 1 Creator workstation. It is in excellent condition, and it works just perfect. I've even managed to score a Sun Microsystems 21" CRT display which is just a beauty. Now, as this monitor is way too big for any room I plan to keep it in, I've wanted to see if I can attach it to a VGA LCD monitor. The thing is, this workstation has the Sun frame buffer, and uses that "wonderful" 13W3 connection. Problem: I've gotten this 13W3 to VGA converted off eBay, as that was supposed to do the job. It arrived, I connected it to my Dell 19" LCD (P190S), but nothing. It kept flashing from time to time, but no picture showed up. After some digging, it seems that the issue is that the Sun systems are using a Sync on Green (SoG) output, so I need a monitor that supports that. Okay - I got a LG Flatron (19") that supports SoG. But again: nothing. Okay, maybe the LG cannot handle the refresh rates, let me get something that a lot of folks in the retro world use: NEC MultiSync 1990FXp. Still nothing, this one does not even flash from time to time. The question: What can I use to connect this old Sun Ultra workstation to a LCD VGA monitor? Am I missing something. Is it the monitor? Is it the frame buffer? Thank you all!
