E5-572G-5577 cannot properly work nvidia 840M 2GB dedicated VRAM

Hi, i recently bought Acer aspire E15 model E5-572G-5577 which came with i5-4210m (2.6 to 3.2Ghz),8GB RAM,Nvidia GeForce 840M 2GB dedicated VRAM,1TB HDD and freeDOS. Since i recieved Win8.1 x64 for my Birthday i bought this laptop without windows and installed 8.1, as Acer claims that fully supports this OS. Everything was ok in installation and i even installed HD4600 driver but when installed Nvidia driver although it looked ok and it was shown in device manager the graphic card wasnt show in my display (only HDGraphics) and in nvidia control panel i had only the 3D settings option but still it seems that 840M hasnt kicked in. I asume its the driver so after many attempt with different drivers i still have the same issue. The laptop is brand new and in OEM 8.1 it seems to work but not for all of us that have a bought copy of Windows. Please help me as i am very frustrated that i have wasted so much money on a Acer with 840M GPU that wont work.

because of optimus technology.

i don't know if BIOS has an option to switch manually the GPUs.

Have you tried to launch any 3D game to check if nvidia will be switched on automatically?

I will try since i get to install Steam. I can't access to the Nvidia setting.I think there is an issue because i even cant see the 840m in power managment but i can see and set the HD Graphics (performance or power saving). Shouldn't i be able to manage the Graphic Card? I know that integrated work with dedicated Card, but the fact i can't control dedicated shows that there is something wrong.

And ty for the fast reply.

And why should Nvidia automaticaly work when i launch the game? Isn't 840M external Graphic Card? HDGraphics is integrated not Nvidia.

Ok. it has optimun technology but why when i play a game and fewer graphics are needed, the nvidia goes off and HD graphicks take over? When again a fight begins nvidia increases power and works smoothly but in that second i have lag. That on/off should be going during a game? Can Acer answer with more than 5 words? For the people who want to work just the Nvidia without the optimus technology is there a way ACER!!!! make a bios that has this option?

ViktorZub

Ok I figured it out, everything is ok (Nvidia forum helped a lot), except that i want to have the option through BIOS so i'll wait for When and If Acer releases an update that solves this (not counting on that). Finaly during the game i have to disable Vsync, it still messes the image, it becomes glitchy and i don't know why.
