Nvidia GTX 770M cannot run with lastest DL 7.4M2 installed
 

Hi all
my system configure is
MSI GT60 2OC 054XN
Win7 X64 ultimate SP1 with the lastest update
Graphic: GTX 770M (drive version 331.93) and Intel HD Graphics 4600

After I installed the lastest displaylink driver,I pluged a 7" Bestview USB monitor and the system executed the first config and required a reboot.
after the notebook finished the rebooting,I found that I cannot play video games with the GTX 700M video card.I had tried BMS 4.32,DCS Black Shark and DCS World, none of them could be runned with GTX770M.It seems that the system always run with Intel HD Graphics 4600.

Any idea?

As you might be able to tell by similar posts, there are some issues with the latest 7.4M2 drivers when used with Optimus (laptop) platforms. (blank screens, DirectX issues)

You can try the 7.4M0 drivers to see if they resolve the problem until DisplayLink releases a new version of the drivers.

Hi,

This should be fixed in the next release due out early December.

Thanks,

Thanks,that's really a good news

Sorry I just try the new driver 7.5M0 but the problem is still not solved.
The nvidia driver version is 331.82 WHQL

Both the Nvidia and Displaylink are installed cleaned

Yup, still broken here too.

Hi,

Sorry - I thought this was fixed - I'm onto this now.

thanks

EDIT: sorry I forget switch my system language from Chinese to English,so if you have any problems I may try it again in English

Would be really nice if you could fix the "Optimus dedicated graphics card not working" bug soon. It's quite annoying! Thank you!
