dual monitor support on T420s with integrated only graphics

[ljwobker]

Anyone know the details on dual monitor support with an integrated-only gfx T420s?
Are there limitations on how many monitors and what resolutions are supported with the intel-only option?

I don't need graphics performance per-se, but I do want to run dual monitors at at least 1920x1200...

thanks...

I believe the Intel on board graphics will only run 2 monitors concurrently. This would be the internal LCD and VGA/Display port output to one monitor with a max res of 1920x1200; or with the internal LCD disabled and two external displays (one via VGA one via DP).

If you got the Optimus discreet graphics option you can get 3 simultaneous displays. With a dock, 4!!!!

Or you can always add a USB-DVI adaptor like this: http://download.lenovo.com/ibmdl/pub/pc ... ly2009.pdf

The intel GPU on the T420s can support 2560 x 1600 with the Displayport.
