LCD Scrub: Get Rid of Unwanted Burn-in
Posted by Greg Healy on 06/7/08 in Featured, Graphics, Home & Personal, Utilities
Burn-in (or Image Persistance), on LCD Monitors, is caused by “the continuous display of static graphics on the screen for extended periods of time.” This causes pixels to become “stuck” and only display one color. If you have ever had this happen to your screens, you know that it can be annoying, and depending on where the persistence is, difficult to work around.
A few weeks ago, I was looking at a photo full-screen in iPhoto on my iMac, when I noticed a line of white at at the top of the screen (pictured below), where the menubar usually ends. Restarting didn’t seem to fix the problem, so it was at that moment, I realized that I might have Image Persistence.

Searching across the internet to get rid of it brought a few different methods, like certain movie clips to play fullscreen, and certain screensavers. After poking around a little, I settled on trying the application LCD Scrub, from ToastyCode. LCD Scrub is a screensaver that is supposed to get rid of unwanted Image Persistence. The instructions were to turn on the screensaver, and leave it for several hours. After following these instructions (I left the screensaver on overnight as I slept) I was pleased to see that I could barely see the persistence anymore. After I had gotten home from school later that day (the screensaver on all the while), I could no longer see the white line.

Of course, the line was never that big a deal in the first place, as it was not visible when the menubar was visible, though it was annoying when in fullscreen. Overall, I was pleased that this application actually functioned as advertised, though your results may vary. Let us know how you got rid of your Image Persistence
LCD Scrub is $18 from ToastyCode.
