This is the 13W3 to VGA (HDB15) analog connector? Not the HDMI connector on the monitor? I've got a ton of Samsung 204Bs at work and they're nice to work on. Ken> It does not work!!

Hmmm... if it was running Solaris I'd say take a look at the m64config command, but that's for Ultra 5/10 boxes. Basically, I think you need to force X to use a certain configuration. What does 'xrandr -query' say? Anything useful? Try editing your /etc/X11/xorg.conf to have a section like this, though you'll need to change the DEVICE from my old Matrox to whatever the Sun is really using.
