It looks a bit "crumpy" tho, but ok.
Whichever software you use to resize your shots make sure that the "Preserve aspect ratio" option is checked.
PS. This doesn't seem to work on Gadwin PrintScreen. If you have a wide-screen monitor you have to set it manually. Try 1024 x 640.
I resized this in IrfanView.

Also press Alt + Enter & take the shots in Full Screen mode. Wait until the pause warning is not visible.
