I tried running DxDiag (DirectX diagnostics), and I noticed that my graphics card is set to the onboard one that comes with the Core i5 processor (some Intel HD stuff).

On my computer, I also have a dedicated graphics card (an Nvidia 310). No serious gaming stuff, I know - just for programming.

However, I would still love to know how to switch to that dedicated graphics card instead.

My laptop is an MSI CX720.

Check your BIOS.

You need to either:

  • Disable the on-board graphics, possibly by disabling any shared graphics memory (or setting allocation to automatic).

Or

  • Set the primary adapter to be the dedicated card, PCI-e x16 or similar (BIOS dependant).

How would I set the primary adapter to the dedicated card? Disabling my onboard graphics card just makes the screen go black. – Mathias Lykkegaard Lorenzen Jan 10 '11 at 18:56
@Mathias - I have no idea what the settings in your BIOS are - almost every BIOS is slightly different. If you have a "peripherals" option I'd check in there for video or PCI or PCI-Express. Otherwise there could be a shared memory setting inside a memory config somewhere. – DMA57361♦ Jan 10 '11 at 19:10

I figured it out.

I had to toggle my prepared graphics processor from the Nvidia control panel (pretty weird), and then it worked just fine. A reboot was required.

How did you do that 'toggle'? I can not do that, even can't disable onboard intel card in bios. I wanna use nvidia card, cos webgl doesn't work with intel. thanx, you if can help! – Pengő Dzsó Dec 27 '11 at 18:59
