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 ;) 2011-09-18 15:42, Jim Klimov wrote:

Yes, the FW is newer than SRSS after all, but not the latest one: GUI4.1_139548-02_2009.05.13.18.59 > The stretching is An artifact of your monitor. The Sun Ray doesn't > control that feature.

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. > But if for some reason you can't disable scaling, the current > firmware supports a resolution of 1440x900 that's closer to > your aspect ratio and might look better scaled than 1600x1200. 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. --
