Force PNG gamma update

I'm not in front of a computer at the moment but I believe forcing the gamma to update requires refreshing the card.  I seem to recall the docs saying to lock the screen, navigate to another card, and go back to the source card, but I believe any action that causes the card to refresh will work.

So I found a post suggesting that after setting the screenGamma to
force the PNGs to update by performing the following:

set text of img 1 to the text of img 1

Well, to quote a famous actor—"The goggles do nothing!".

What's the best way to successfully force the PNGs to render properly
after a screenGamma setting?
