3D video controller driver error

[suyashD]

hello sir,

          I have purchased HP p077tx model laptop,it comes with gt840m but when i am trying to install the drivers it shows the error message"no compatible hardware found" during installation.Furthermore when I checked the device manager it shows no gt840m in the display adpters list,the 3D video controller is showing no driver installed on the PCI 10 bus.

please help

Thnaks.

Hi:

Did you first install the Intel chipset installation utility and Intel HD graphics driver and reboot before installing the nvidia graphics driver?

hello sir,

YES it worked but now i am facing another problem my laptop display is configured to run on the intel hd gpu not on the gt840m which is not delivering smooth performance in gaming. Pray tell me how to switch between them.I have tried disabling,uinstalling the intel one but then the microsoft basic  display utility takes its place,I even opened the nvidia panel and changed the global and application setting to high end nvidia processor but it is still showing the same as earlier

Please provide me with solution

Thank you

You're very welcome.

Unfortunately, I don't know how to work a notebook with switchable graphics because I don't own one and there is no documentation from HP on how to do it either.

This is the only info I could find which doesn't seem to be of much help.
