--scale has nothing to do with the final scaling, you might be thinking
about --set "scaling mode" $mode, which is about how the HW should
behave with non-native resolutions.  At least that's the case with LVDS
outputs, not sure if my DVI has such, I don't have such an output
available right this moment.  $mode is as follows:

• "Center" will not stretch at all and 1 px will be 1 px.
• "Full" will stretch the image to the full available space of the
display, with no regard for the aspect.
• "Full aspect" will stretch the image until one side is as big as the
display, aspect is retained as normal.

The last two modes can show up very blurry or just plain odd, depending
on the smoothing done by the display.

To list the current scaling mode, try xrandr --verbose
