Image Retention Test
A simple test to check your Retina MacBook Pro display for image retention also reported as "ghosting". As featured on Gizmodo!
- Read the FAQ below for tips and to better understand the test.

What is "image retention"?
Image retention is a condition where a display holds a partial image of a previously displayed screen. This effect shows up when a "ghost" of a previous image on your screen shows up over the former image.
What does image retention look like?
This Flickr Set I created shows a pretty good example of before and after of a screen suffering image retention.
How do I best use this test?
One of the major causes of image retention in Retina MacBook Pro models is when the GPU is heated and in a working state. For best results, use the following tips:
- Ensure the test is run for 10 minutes
- Do not change screens during the testing process
- Do not closely watch the test as it runs - your eyes have a tricky form of image retention of their own!
- Run a graphics intense process for a few minutes prior to running the test and keep it running. This might be something like running a game or processing video.
How does this test differ from Apple's own test?
The problem I found with Apple's test was that when the screen faded to black a lot of the signs of retention didn't seem as apparent. I made a version of their test which would fade to different colors and offer more extended periods for better testing.
