Hi Micha -

Thanks for the thought.

Do you hook your external display up via the DisplayPort (or DVI)?  Will
the discrete graphics drive e.g. a projector hooked up to the VGA port?  I
could get the NVIDIA card to run the T520 just fine, but was not able to
get it to push bits to the DisplayPort or the VGA.  Did you need to tweak
anything in the xorg.conf or anywhere else?

That is what I do with my w520.


It looks like the w520 comes with the NVIDIA Quadro 1000M Graphics with 2GB
DDR3 Memory, so that may be able to handle driving larger displays.

When driving via Intel Integrated graphics: xrandr puts the max at
8192x8192, I've not been able to go beyond 3200x1200 which is just shy of
the reported <http://www.nvidia.com/object/nvs_techspecs.html> 4,096,000
reported max resolution of my card.

Thanks again!
