4.1 Recommendations for daily operation
Optimize the lifetime of your display
Enabling the Display Power Management System (DPMS) of your display will optimize its diagnostic life-
time by automatically switching off the backlight when the display is not used for a specified period of time.
By default, DPMS is enabled on your display, but it also needs to be activated on your workstation. To do
this, go to “Power Options Properties” in the “Control Panel”.
Barco recommends setting DPMS activation after 20 minutes of non-usage.
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.
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 diagnostic
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 mis sing pixels, consult the dedicated white
papers available at w
ww.barco.com/healthcare.
Enhance user comfort
Every Barco multi-head display system is color matched with the highest specifications in the market.
Barco recommends keeping color-matched displays together. Furthermore, it is impor-
tant to use all displays of a multi-head configuration at the same rate to preserve color
matching throughout the economic lifetime of the system.
