nVidia Settings

CODE

rundll32.exe nvcpl.dll,dtcfg setview [attached monitor #] [format] [device]

Where...

- attached monitor number is in the format of just a single number. Ex: 2

- format is one of the following

• • standard

  • clone

  • hspan

  • vspan

  • dualview

- device is optional, to specify what takes primary and secondary

Available values are A - analog, D - digital display, T - TV. The best way to explain is by example.

CODE

rundll32.exe nvcpl.dll,dtcfg setview 1 clone DA AA

This line will set display number 1 in clone mode, setting the first attached [D]igital display as primary and first attached [A]nalog display as secondary.

You could have multiple digital displays and they would be labeled: DA DB DC successively.

CODE

rundll32.exe nvcpl.dll,dtcfg setview 1 clone DA DB

This line will set display number 1 in clone mode, setting the first attached [D]igital display as primary and second attached [D]igital display as secondary.

Here's an example of my situation: I have a 32" LCD HDTV and a 20" LCD computer monitor. Because the aspect ratios are different, I have to use different settings when watching DVD or TV on each display. Note that the HTDV is using a VGA cable, and the monitor is using a DVI cable.

This command line will set the 20" monitor as primary while still allowing me to see a display on the TV set:

rundll32.exe nvcpl.dll,dtcfg setview 1 clone DA AA

This command makes the HTDV the primary display.

rundll32.exe nvcpl.dll,dtcfg setview 1 clone AA DA

If I was using 2 DVI connectors (one going to the monitor's DVI port and one going to the HDTV's HDMI port), the command lines would look like this, respectively:

rundll32.exe nvcpl.dll,dtcfg setview 1 clone DA DB

rundll32.exe nvcpl.dll,dtcfg setview 1 clone DB DA

Reversing these two lines may be necessary, depending on which monitor the video card sees first.
