Just for the record: The DP on the W500 port is only wired to the NVIDIA 
graphics. It is not usable with the Intel internal graphics. This still 
annoys the heck out of me and is worth mentioning :)

However, the VGA is usable and I do this to run it at 1920x1200 (first 
line is the kicker):

xrandr --newmode "1920x1200_50.00"  158.08  1920 2032 2240 2560  1200 
1201 1204 1235  -HSync +Vsync
xrandr --addmode VGA1 1920x1200_50.00
xrandr --output LVDS1 --mode 1920x1200
xrandr --output VGA1 --left-of LVDS1 --mode 1920x1200_50.00

... which gives me 2 two "Full HD" screens. The VGA is connected to a 
Samsung 23" monitor with a native resolution of 1980x1200. Yes, it's a 
bit blurry but very well usable.

Again, I'm using only the Intel graphics. The other one is disabled in 
the BIOS and not there (extending battery life).

Good luck,


PS: Thanks again to whoever posted this "fix" first on this list!
