View Full Version : Optimus on G750JZ/JM/JS versus G750JX/JW,JH

Can someone explain how the implementation of Optimus differs on these two series of notebooks? Somehow the JX series can run the Nvidia card on OS X while the JZ series can't. Is there some kind of software switch in Bios or a different hardware configuration?

Thanks for your interest.

There is no Bios configuration, I am returning a JS as we speaking just because of the Optimus technology and very glad that I kept the JX!
Optimus get's itself involved in everything even when you try to configure that it's not the primary GPU, stay away from this year G series is my advice to you... Get a G750JH if you got the cash for it.
