note:
If you cannot select the native resolution after updating the video drivers, the graphics adapter
in the computer might not support that resolution and might need to be upgraded.
If you updated the video drivers, set the correct display resolution, and the problem still occurs,
continue to the next step.
9. If the computer connected to the display is using Windows 7, complete the following steps:
1. Start the computer in Safe Mode. Restart the computer and press the F8 key repeatedly
when the first screen displays. From the Windows Advanced Options Menu, select Safe
Mode, and press Enter.
2. If the computer connected to the display is using Windows 8, refer to the Windows 8
Safe Mode document.
3. While the computer is in Safe Mode, press the Auto button on the front of the display to
run Auto Adjustment again.
4. If the display is sharper in Safe Mode, while still in Safe Mode, reinstall the display
drivers from the CD that came with the display.

Screen flickers, unstable image
If the screen flickers, make sure the display settings in Windows match the native resolution and refresh
rate for the display. Find the native resolution of a flat panel display on the box, in the specifications, or
in the printed material that came with the display. Some common native resolutions are 800 x 600, 1024
x 768, 1920 x 1200, and 1680 x 1050. The most common refresh rate for LCD displays is 60 Hz. This
normally cannot be changed for flat panel displays using Plug and Play settings. However, if you are
using special video software to increase or decrease the refresh rate, change the refresh rate to match
the default refresh rate specification of the display.
note:
If your screen flickers in Windows 10, it is usually caused by incompatible apps or display drivers. To find
out whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based
on that information, you'll need to either uninstall the app or update the display driver.
