I have a Sparc Station 5 that I am intending to get up and running
with SunOS 4.1.4 on one disk and OpenStep 4.2 on the other. The last
remaining hurdle is video. The CG-3 card that is in it either is not
able to push the 1024x768x77 it's supposed to or not able to talk to
any of my monitors.
I'm deep in the heart of flyover in Hayward WI so trying a to find
another video card is easier than a different monitor.
I'm looking for an S-Bus CG6 of the TGX or TGX+ versions or a Sparc
Station 5 specific S24 24 bit video card. The TGX cards are supposed
to be able to push a resolution of 1024x768x60 that should be able to
be used by generic SVGA monitors.
Thanks for your time and any assistance.

1152x900 sounds about right for the max (I don't think those cards would do
1280x1024).

My recollection is that the CG3 (and the CG6 as well) is a fixed
rate card for 1152x900x8 at 66Hz.

The cg3, maybe. The cg6? Perhaps some of them are, but, in general,
they are not; every cg6 I've seen has a medium number of
resolution-and-frequency configs available (typically a dozen or so,
from something like 640x400x75 to 1152x900x60). Some
(a very few, in
my experience) support higher resolutions as well; I know I've
seen
1280x1024 and I think I've seen 1920x1080 and 1600x1280 - but only on,
like, one or two cards.
On many machines, it's possible to use semi-arbitrary resolution and
frequency settings. I worked this out in 2008 and sent mail to at
least two lists about it, but for the cg14;
http://mail-index.netbsd.org/port-sparc/2008/08/08/msg000133.html and
http://www.sunhelp.org/pipermail/rescue/2008-August/124772.html are the
archived copies of the two messages. (The sunhelp.org one got mangled
slightly by something that mistook a string with an @ in it for an
email address; the netbsd.org one looks intact.)
I recently tried to get an LX's onboard cg6 (with a VSIMM for the extra
RAM) to drive a slightly unusual flatscreen at its native resolution
(1680x1050, I think it was); while mostly neither here nor there, I did
learn that it can support only a small number of pixel clock
frequencies, so you have to be careful. I don't know to what extent
this is true of other cg6s....
