Dell 7720SE updating drivers from Intel website in order to get WIDI working

Question

Hi, I was wondering if someone could help me with this. The issue is 2 fold. The end goal, is to get WIDI working. According to the intel site my machine is compatible, processor is compatible, GFX card is compatible etc, the compatibility tool runs and confirms this, but when I try to install the software it tells me my machine is not compatible.  So, the first thing that comes to mind in this situation is - lets update the drivers. So I head on over to the Intel website and download them. I've tried installing both from the update tool and downloading the exe file, but each time I have the same problem. Install drivers (15.33 for display and 18.1 for network card), reboot, look into device manager at the driver versions and oh its still reading the old version drivers as if it hasn't updated and I don't know why. I've always built my own systems and so, never encountered this type of issue - i presume its some sort of lock Dell have put on the machine - and I dont know how to solve it. The system is well outside warranty so I'd like control over how and what I update if possible.... Any ideas guys? Thanks Andrew

The system needs an Intel wireless adapter as well - if it's a Dell wireless card, that's the point of incompatibility.

This has the 3D video - it has an Intel Hd card - 4000 I believe and an nvidia card - not got the system on at the moment but can confirm later if need be

Thanks The device is listed as an Intel Centrino wireless-n 2230 so I would presume this is an Intel card? Thanks Andrew

I've now taken the cover off the back and the card is stamped Intel not dell with the model and serial numbers etc - I tried to scan the QR code but it was not recognised

Is this the standard 2D model, or the model with 3D video?

That's why you're seeing WiDi disabled -- the version with 3D has the Intel GPU permanently disabled and runs the nVidia GPU only.

There are hybrid systems (now and when yours was available) that will work with widi -- but yours will not, since the Intel Widi requirements need an Intel GPU.

Hi

Thanks for the reply

The system does have an Intel GPU - it uses the Intel unit in Windows and switches to the nvidia for more intense applications - I can select program by program which uses the Intel and which uses the nvidia.

If I run dxdiag it lists the Intel unit

Sorry I've just realised that you don't mean 3D card but 3D display - old school terminology for a gfx card... Mine is the hybrid witgout 3D - it has an Intel had graphics 4000 and a GeForce 650

Not if it's the 3D version - yes, the Intel GPU is there -- but the nVidia GPU is permanently hard-wired to the display -- the Intel GPU is completely bypassed.

ONLY in the non-3D systems is there a hybrid setup where both GPUs are used in tandem with each other.

Hi all Has anyone got any other advice of how to update the drivers in order to get this working. I am pretty convinced it should work, but I am running out of ideas! Thanks, Andrew
