This document,
http://www.dell.com/content/topics/global.aspx/vectors/en/2003_cvt?c=us&l=en
&s=corp is 3 years old. There's no standard yet?
That's right, there's no standard yet. There probably never will be,
because VESA seems to have moved away from publishing specific
timings and instead just suggests approximations. For most of the
recent panel timings t's up to the manufacturer of the monitor to
decide what timings to accept and what variances to accept around
those timings. You see all of those "GTF" annotations in the "Note"
column for the 1680x1050 entries in the table at the end of that web
page? That's what "GTF" means.
So don't expect Sun Ray to offer a baked-in 1680x1050 timing in
'utsettings' until there's enough customer demand to justify spending
the time, effort and money to acquire and test a representative sample
of 1680x1050 panels so that we can find out what timing has the best
chance of working reliably. So far no-one (and I mean no-one) has
filed a request for it with Sun Ray engineering. I think I've seen
three individuals ask for it, including you.
All of the above applies to widescreen TV formats, except even more
so. Those guys can't even seem to agree on how many rows or
columns they're going to support, let alone settle on a common timing.
There is an actual RFE open for that, albeit with no customers
attached to it.
It was pretty simple to get Solaris 10 Xfree86 to work with my 1680x1050
display, shouldn't be that hard to plug the timings into SRSS....
If you just want it to work with your particular display then sure, that's
probably doable. Perhaps it's already been done. If only there was a
searchable archive of this list's traffic, and if only there was some way to
find that archive from a pointer on the list's home page, and if only that
archive went as far back as, say, August 29th of last year, and if only
you were somehow able to find a series of messages with the subject
"Custom graphic resolutions using utresdef (Sunray Software 3.0)" then
perhaps you would already have been able to get it working. Ah, if only.
