Don't do what I did, buying a Lenovo 'multimedia' machine that included as standard a nVidia GeForce GT 750M discrete GPU with an Intel Core i7 processor chipset, including the 4600 graphic chip, and then waste a year trying to figure out what was wrong while my very pointed and direct questions to Lenovo hardware support were answered by talking around the issue(s). I sent a screen dump of the graphic showing the PhysX connections to video ports; strange that the nVidia had none and the 4600 had vga/dvi/hdmi.
I found this document ... too late.

Note on page 3 that the nVidia GPU PhysX acceleration is not available if there is a non-nVidia graphic processor in the system even if it is not being used for rendering!!!
And there's more, much more regarding the OS, VGA/DVI/HDMI, what to use and what not to use when installing drivers in Windows 7 (and 8), etc. etc. etc.
Even if you're using other hardware combos set up by OEMs, these days take nothing for granted and if you've already bought your machine but the problems won't go away permanently, don't roll over and play dead; no support, then return it. Too late, then just spread the word to help others avoid the mfg and seek support elsewhere to make the most of what you have. In the meantime read that link!
