There seems to be some confusing on the use of the term "adding resolution"
when referring to images.

Resolution is simply a measure of the amount of pixels (X/Y counts) and a
pixel-per-inch (ppi) setting. Resolution CAN be increased--period. This is
typically done in a program like Photoshop. (Whether one should do this for
screen captures is another issue and not the point.)

The confusion among some is whether this is adding "real" pixel data,
therefore enhancing the detail of the image. It is not. Detail, or real
pixel data, can only come at the time of initial capture.

Some quasi-experts were claiming that resolution cannot be added at all, but
what they were really referring to is detail by means of original pixel

Note: Adding resolution is not the same as re-assigning the ppi but keeping
the same X/Y pixel amounts.

To repeat my original advice:
1] Do not use JPEG format, but PNG, TIFF, or possibly GIF.
2] Do not add resolution, but use as is.
IF--and only IF--additional resolution is necessary for prepress purposes,
use nearest-neighbor interpolation, not bicubic.
3] Monitor display setting (aka monitor resolution) is only important when
capturing entire screen layouts, not for individual dialog boxes.
