Display not very visible particularly in direct sunlight

December 2010

Each model rugged handheld computer is designed to provide the best available display technology for outdoor visibility. Available display technologies have improved over time, as is visible on each generation of our products. But some conditions can still cause the display to be somewhat less visible. Such conditions can include (but may not be limited to) the following.


  • Display backlight and/or contrast is dim (particularly with transmissive instead of transflective displays). You may be able to manually adjust this setting to improve visibility.
  • Screen protector sheet is installed over the display. Crystal clear (glossy finish) protectors may cause undesired reflections or glare, while anti-glare (matte finish) protectors may allow less light to and from the display. Removing or swapping the screen protector may help.
  • Wearing polarized sunglasses (particularly when the polarization of the glasses aligns with the polarization of the display). Switching to different or non-polarized sun glasses may help. A polarized screen protector sheet may also be available, such as we provide for the Mesa 2.
  • The display controller is not behaving properly, requiring a Hard Reset (hold the Power button for a full count of 20 seconds) or extended power removal (pull battery pack(s) and wall charger for at least 20 minutes).
  • The display is damaged, partially disconnected, or has a defect requiring repair or replacement.
