To Resize it select Image: Resize: Image Size. You can type in your dimensions in this dialog box. You’ll get some distortion if you want exactly 3×4 because it won’t stay proportional. (A proportional resize would be 4×2.667 or 3×4.5.
Tim,
If you are only trying to resize for screen viewing, I would try;
Image>Resize>Image Size
have the Resample Box checked
change the unit to Percentage
type in 75 (for the %)
and then let the program do its thing
I have not tried this, but it seems like the easiest way to go and it should work.

Tim,
My earlier post assumes you are opening this in a browser, because if viewing in PSE, the display size would be dictated by the Zoom factor you have selected.
