This topic came up in another thread. This is an attempt to show that although there is NO WAY to create source material that does not exist to begin with, it still is possible to improve upon the presentation of that source material to make it appear as though there is additional detail.
Since a picture is worth 1000 words...
Eric Clapton, at native resolution:

The SAME EXACT source picture, on a higher resolution device.

Note that this picture still has the same source material, upscaled for a higher resolution display. Although NO additional information is available from the source material, notice that additional detail that actually WAS in the source may be easier to make out at the higher resolution.
Specifically, note how the ring on the right hand, the watch on the left hand and even the eyeglasses themselves become more recognizable in the upscaled image, even though there was no more "information" in the image than the original picture had.
Of course, there is simply no substitute for having a higher quality source to begin with:
