Lenovo Y400 external graphics issues

helpdesk

#1

Hi everyone.
I have a Lenovo Y400 laptop and a GTX1070 attached to it using an adapter.Is it possible to make internal display accelerated by the external GTX1070? Is using DXGI (technology which Looking Glass based on) possible to copy frames from GTX1070 to internal GT650M which attached to internal display?
Thanks buds!

Yes, but you loose some performance since using more bandwidth back to the monitor

How to ?

You have to send the image back down the wire to the internal display, it’s not that much tho
