2. Use a screen saver to avoid image retention
Prolonged operation of an LCD with the same content on the same
screen area may result in a form of image retention.
You can avoid or significantly reduce the occurrence of this
phenomenon by using a screen saver. You can activate a screen saver
in the "Display properties" window of your workstation.
Barco recommends setting screen saver activation after 5 minutes of
non-usage. A good screen saver displays moving content.
In case you are working with the same image or an application with
static image elements for several hours continuously (so that the
screen saver is not activated), change the image content regularly to
avoid image retention of the static elements.
3. Understand pixel technology
LCD displays use technology based on pixels. As a normal tolerance in
the manufacturing of the LCD, a limited number of these pixels may
remain either dark or permanently lit, without affecting the
performance of the product. To ensure optimal product quality, Barco
applies strict selection criteria for its LCD panels.
To learn more about LCD technology and missing pixels, consult the
dedicated white paper available at www.barco.com/healthcare.
4. Enhance user comfort
Every Barco multi-head display system is color matched with the
highest specification in the market.
Barco recommends keeping color-matched displays together.
Furthermore, it is important to use all displays of a multi-head
configuration at the same rate to preserve color matching throughout
the economic lifetime of the system.
