Corrupted Video
•  Text and graphics appear fuzzy
•  Image corrupted

1.  Set System Preferences/Display to a native 

resolution. Non-native resolutions are unable to 

produce optimal clarity.

2.  Make sure all relevant software updates have 

been applied. Graphics driver updates may be 

included with software updates.

3.  When the issue occurs take a screenshot of the 

display (Command-Shift-3). View the screen shot 

file on another known-good computer. If the 

image corruption can be seen in the screenshot 

then the issue is with the video drivers, software, 

or video/logic board. If the issue cannot be seen 

in the screenshot then the display and cable 

should be tested further.

4.  Boot from install DVD or another known-good 

volume to determine whether a potential 

software/driver issue exists. 

5.  Verify if issue can be reproduced on both 

DisplayPort and HDMI ports.
