You'd be wasting the resolution of your cameras to capture at a lower resolution and I wouldn't recommend this. Typically, the higher resolution (larger pixel dimension) the image, the more flexibility you'll have for future use.
The thing you need to keep in mind is that you need to maintain (or constrain) the aspect ratio (width vs. height proportions) of your image; otherwise, it will appear distorted. Take the beautiful 2852 x 4304 pixel image on the left - if you simply make the width 1920 and the height 1200 you will end up with the appropriately sized image on the right (not exactly what you want, I assume):
For the image above, here's what I would do in GraphicConverter...open the original image, select Picture-->Size-->Scale. Make sure "Keep proportions" is checked, then in the "Dimension" area select "Pixels" from the dropdown menu (probably "inches" by default). This will show you the width and/or height of the image in pixels. Change the width to 1920 and you will see the width change proportionally. Click "OK".
Select Edit-->Select All and then Edit-->Copy. Now go to File-->New and create a new image that is 1920 x 1200 pixels and then select Edit-->Paste to paste your image. Use the hand tool to position the image and then save it as a JPG to be used as your desktop image:
Alternatively, if you want a little more wiggle room horizontally, you can set the initial scaling to something a little larger than 1920.
Make sense? The exact steps you'll take will depend on the original image's resolution, subject matter, and desired result, but this should get you headed down the right road.
