Comment:
I can confirm there's a problem when attempting to use the Dual Head on
the Intel 945 Express. This presents a significant visual miscalculation
to users of netbooks and many entry-level laptops.
Without looking at any logs - it appears that the values that define each
monitor are being mixed, and consequently, the visual output can be
unusable. For example, the output on desktop display is scaled to the
width of the 2nd vdu and scaled to the height of the 1st vdu, and finally
clipped/cropped (not rescaled) to the resolution of the 1st vdu. In other
words its a mess.
No Dual Head features are provided in the display settings and the
reported resolution matches the clipping but not the rendering. Did that
make sense?
