[rescue] Re: SGI Video - PC Monitor (*)

[Eric Webb]

I hate to bring this thread back up, but I just got my I2 today and I'm 
trying to get something to display it with.  

I have a 13W3 -> HD15 borrowed from an RS/6K box.  The cable is good because 
it works on my SS20.  However, my 19" SVGA won't display anything.  It's 
reporting 0khz horizontal and 72.2khz vertical.  This tells me that the hsync 
line is either grounded or not connected and the vsync line probably is 
connected.  I think this is responsible for confusing my monitor into 
thinking it has composite sync instead of SOG.  Does anyone concur?

Now, this tube is an Envision EN-910e.  Certainly not top of the line, so it 
wouldn't surprise me if it doesn't do SOG, but I can't definately say that it 
doesn't.  (Anyone have one?)

Would it perhaps help to craft a cable/adapter that doesn't connect the sync 
lines just in case they are the source of the confusion?  Maybe my 13W3->HD15 
is wrong/bad?  I have a scope, can anyone tell me what I'm looking for?

-E.
