I recently got an Asrock ION 330 as my HTPC and it runs with an nVidia ION GPU using the nVidia Control Panel. Older versions of nVidia Control Panel came with the application nView, which easily allowed you to change resolutions. You can still get the application, but I needed a function, which changed my resolution between two set resolution, namely 1080p and 720p. The reason was because on my TV with 1080p the text is too small for me to read, whereas on 702p it is big enough.

But, there is no application which does this, i.e., easily switch between two resolutions. Even with nVidia Control Panel on Windows 7 and through Windows 7 own WMI you cannot change the resolution.

Step one was to was a program which could easily change my resolution through a command line and then write a VB script to do the change for me. This was I could assign the VB script to run on one single hot-key command.

… and this is what I have done.

1. Download and install the program Display Changer from 12noon.com (awesome little application) (http://www.12noon.com/)
2. Download and unzip to your preferred location my script setResolution from http://debrass.net/wp-content/uploads/2010/04/setResolution.zip

Now open the setResolution_settings.ini and enter in the full paths to Display Changer’s dc.cmd and dccmd.exe or dc64.exe and dc64cmd.exe if you installed the 64-bit version of Display Changer. Currently it is set to paths for the 32-bit versions of Display Changer on an English Windows 7 OS.

You will also need to enter the two resolutions you want to change between, specifying each on individual lines. Currently it is set to switch between 1080 (1920×1080) and 720 (1280×720).

If you need any help, drop a comment.
