How to change display properties in IORegistry


1 post in this topic

Recommended Posts

When I view the display characteristics in the registry explorer, for:

 

display@0

 

the 'model' property is showing up as ATI Radeon 4830

 

but I have Nvidia 8600 GTS in the PCI-E slot.

 

Where would the device description be set for the ATI Radeon - I'm assuming an Info.Plist somewhere? I checked IOPCIFamily and IOGraphics but did not see anything helpful.

 

Some more info: under System Profile, the Chipset Model shows up as the ATI Radeon HD 4830, but the Vendor is NVIDIA (0x10de) with the device ID 0x0400 and total VRAM is 32MB.

 

Any pointers to how to set this right much appreciated.
