M17x HDMI-in help

does anyone know how to fix this? i know its a driver issue and all but does anyone know how to get around this?

 

This is someone else's finding. I saved it to a text file on my PC. This may be in the owner's thread sticky. I know it is in another thread but I'm too lazy to search so here is a paste of the info:

Nvidia support asked me to first point out they in no way indorse editing your Registry, recommend against. You proceed entirely at your own risk. Back up your system first etcetc…. And this workaround not yet being made public.

Nvidia recommend: “recommendation is for users impacted by this issue to simply contact Dell directly and ask for a driver update with the fix”.

**To use at your own risk**

1. Make sure you are running the 296.10 driver or newer driver.
2. In Registry editor Go to registry location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{active graphics device}\0000
(You will have to work out which is the active graphics device if you have more than one listed)
3. Create a new key by right-clicking on the right-hand pan of the registry editor window and then select "New" > "DWORD (32-bit) Value".
4. Label the name of the new key as "DisableHPDFakeMonitor".
5. Once key has been created, double click the new key and then add the "1" to Value data area. Click OK to save.
6. Restart Windows.
7. Check HDMI-In functionality.

**To use at your own risk**

I've been advised this will not need reapplying if doing a driver update, but will if the driver is uninstalled and a new driver installed (i.e. clan install).

Hope that’s some help to those suffering with this issue.

You can also try updating the VBIOS, here's the link for your graphics card BIOS:

I was in a bit of a hurry when I posted earlier. The problem is not stated very well at all by the OP. My assumption from looking at the signature is that the OP has a 3D m17x R3. If you load any video drivers newer than the ones issued by Alienware on the 3D laptop, your HDMI input will no longer function. It will display the picture from the input for about one second and then the screen goes black until you unplug the input device. Louis told us this was due to a conflict between a change NVidia made and the 3D implementation in our laptop that would be difficult to resolve. NVidia gave the workaround to a forum member on a support call. It has worked great for me on every driver I've used since it was published. It DOES NOT work on Windows 8 even if you use the same driver you were using on Windows 7. However, it works perfectly on Win7.
