As a follow-up to my own post, and with a new question, I report:

1) The DVI cable and digital resolution setting did not solve my
problems regarding image upscaling by the monitor. I did not
yet try to set 1920x1080@60d, but I guess it won't work anyway
due to limitations of SR2 video chip.

I did not yet craft an "overscanning" mode which would fool the
monitor into a 1080-high canvas with a 1050-high image by SR2.
So any pointers at that (or blunt "won't work!" statements)
are still welcome ;)

2) I contacted BenQ and asked them if it is possible to disable
image stretching in this EW2430 monitor.

They wrote "no", but that such disabling should be a feature of
the more advanced and expensive model EW2430V.

In fact it is not a very big "bummer" to me because I wanted to
buy that one originally, but it is not yet on sale in shops. I really
hope that my shop (that I bought the current monitor from) would
allow me to trade-in the current monitor at original price and
exchange it for the better model whenever it hits the shelves.

NEW QUESTION:

3) While fiddling with resolutions I noted that (apparently) this
monitor does not do minimal standard resolutions with which
the SunRay powers up, as well (whatever that is - 320x200?
640x480?) - the monitor just displays an "Out of range" error.

However, after a SunRay session with a supported resolution
is established, during "soft reboots" of the DTU it displays
the Sun Ray OSD using the same supported resolution.

Now, I wonder if it is possible (or can become possible after
somebody posts an RFE) to save the default resolution to
be used just after power-up - instead of the hardcoded one,
as one more setting of the GUI firmware. Perhaps it can
be not a true default, but enabled by some key sequence
during power-up - so the hardcoded default res. is still
there in case the user switches monitors ;)

For example, until I got my (VPN) connection working, I was
completely blind regarding the DTU - I had no idea if it was
working at all, or which error code it would be displaying.
Not very cool!

Now, for the bonus question from my original post: did I follow
the correct procedure to enforce a new resolution for my DTU
(i.e. passing "utrestart -c"), or is there a cleaner way without
disrupting other users and sessions? Thanks ;)

PS: The bonus question is also still pending ;)

Yes, the FW is newer than SRSS after all, but not the latest one:
GUI4.1_139548-02_2009.05.13.18.59

I hoped for that. The LCD unit is a BenQ EW2430, and with analog
input it offers two modes of scaling: "Full" (filling all the 24" with my
picture) and "Aspect" (scaling up to the display on one side, and
leaving black bands around the other sides). There is a grayed-out
setting like "Overscan" which I think is reserved for digital links.
And there is no "Off", at least not for analog input.
So far "Aspect" with 1680x1050 gave the neatest results, but some
30 pixels in between are still stretched.

Thanks, I'll try that.
And I still have a slim hope that the digital link may fix up the
monitor's brain about resolution too ;)
From what I tested, it does drive both 1680x1050 and 1600x1200.
I hoped it might be possible to fool the monitor at the signal level
by "overscanning" the frame as 1680x1080 or likewise, while
having the SR2 maintain an image of 1680x1050.
