Recommendations for using your display system
1. Optimize the lifetime of your display
Enabling the Display Power Management System (DPMS) of your display (in the display’s
Settings menu) will optimize LCD backlight lifetime 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.
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 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 missing pixels, consult the dedicated white
paper available at www.barcomedical.com.
Unpacking and handling tips
The display is a precision instrument that requires proper care to maintain product
operation and adherence to specification. Unpack the display and components carefully,
then set up and handle the unit properly to avoid damage to the LCD panel.
• Always lift and carry the display with 2 persons.
• Use both hands to grasp the display case when lifting it from the shipping
carton, but avoid touching the screen.
