Nvidia monitor scaling fix

Apologies if this has been mentioned anywhere before, but I've had a look and can't find it.

There is a fix for the broken Nvidia display adapter scaling (1:1 mapping) setting in the recent drivers. It's a registry fix buried in the Nvidia support knowledgebase. I tried it last night and, although I didn't see any "Resize HDTV Desktop" option like it says I should, I tried changing the scaling option to allow my monitor (Dell 2407WFP) to do the scaling and the setting actually held after I closed and reopened the Nvidia control panel. I then went into NFS Carbon (max 1600x1200 resolution) and was able to change the monitor's scaling option to 1:1 instead of it being greyed out due to the driver.

Hope this helps a few other people.

Details below (thanks to a thread at the guru3d forums http://forums.guru3d.com/showthread.php?t=224619):

Why am I not able to resize the HDTV Desktop (adjust overscan compensation setting) with GeForce 8800 based graphics cards on Windows XP?

Overscan compensation is not supported on GeForce 8800 based graphics cards when connecting to many HDTVs over a digital interface (i.e. DVI) with the default driver settings. However, with ForceWare Windows XP drivers v158.22 or higher, overscan compensation over DVI outputs can be enabled via a Registry Key workaround. To enable this workaround, perform the following steps:

1) Download the .zip file linked below. The .zip file contains 2 executable files which can be extracted onto your PC.

2) Double-click the "EnableOverscanCompensation.exe" executable. This will run a macro to create the "EnOverscanComp" Registry Key in the Windows Registry.

3) Re-boot your PC. (Note: we have seen one PC configuration which requires two re-boots).

4) Open the NVIDIA Control Panel by right clicking on the Desktop and selecting "NVIDIA Control Panel". From the "Resize HDTV Desktop" option in the navigation pane of the NVIDIA Control Panel you can resize your Windows Desktop to fit the viewable area of your HDTV.

The above workaround can also be used to enable fixed aspect ratio scaling on similar display configurations.

Note: this workaround will disable HDCP (high-bandwidth digital content protection) support, which is required for playback of protected HD-DVD and Blu-Ray DVD content over digital interfaces. To disable this workaround and re-enable HDCP support, remove the EnOverscanComp Registry Key by running the DisableOverscanCompensation.exe executable and then rebooting your PC.
