Tech Tip: Protect Displays from Image Burn-In or Retention


Displaying a static image on an LCD for too long can cause “image retention” or “image persistence”. How do professionals avoid this?

LCD crystals develop memory from static images like task bars and icons. A faint image appearing in an area of the screen where medical images are viewed can negatively impact the image quality. So how does one avoid image retention?

Vendor-recommended DPMS (Display Power Management Signaling) Settings. This consists of setting the displays to sleep after a certain amount of inactivity, using appropriate background coloring and using a screensaver.

  • Implementing a screensaver is the easiest way to prevent image retention and alleviate an existent persistent image. You can activate a screensaver in the “Display Properties” window of your workstation. We recommend setting screensaver activation to between 5-20 minutes of non-usage.
  • Setting your displays’ sleep mode to activate after approximately 1 hour of inactivity will keep the display active, but the screensaver and back light will not be active. The displays will still be “warm” and usable immediately after waking.
  • Using a dark, solid background color (and not a background image) is best as displays sitting idle are typically seen with a homepage-type image burned in.

Best Practices:

  • Make sure all new workstations are set up with a standardized setting for a screensaver (such as Mystify) – moving images are best in order to alternate active LCD crystals.
  • Set displays to sleep mode in order to avoid static image elements.
  • Many organizations standardize a background image. Radiology departments, and computers used for Diagnostic Imaging should have their own policy with a solid, dark background.
