How to test your apple iMac screen
No CommentApple iMac is so short on iMac 27-inch that they are simply paying 15% extra to customers who can return faulty iMac. In earlier post apple iMac review, we reviewed iMac as a product. Now let us have a look at how can you test your iMac screen and may sell back to Steve Jobs for 15% extra $$. Let us take a look at what are the steps involved in testing your apple iMac screen.
Have a close look at image:

How to carry out test on iMac screen:
Go to the link below with the height and width of your window maximized,

- While focussing your eyes on the grey bars at the bottom
- Resize the height of your browser window so that the grey boxes are almost touching
- Resize the browser back to full size
- Repeat steps 1-3 several times. Do the test while you are looking directly at the screen, do not tilt your screen up or down. Align your eyes perpendicular to the screen.
Note: Your screen may have the yellow tinge on a corner as opposed to the entire bottom.
While testing make sure that two bars appear indistinguishable from one another during entire length of the test. If there is slight shift in color LCD do not worry. However, there should not be significant color shift. Most of the displays with the issue have a noticeable much warmer (yellowing) tone towards 1/3 bottom of the screen, as illustrated in the photos below:
The grey bars look similar when they are closer to one another as displayed at the top of the screen. Yelloing issue starts from middle of the screen and continues till bottom of the screen. Yellowing issue will become more significant if you are testing iMac screen in a dark room. It will increase if you lower the brightness. Also note that sometimes in very bright condition yellowing is more subtle.
Do Not Tilt the Angle. If you do tilt the screen upwards, the yellow will fade — BUT as this happens, the top of the screen turns Purple, which will be more difficult to notice in grey. Anyway, nobody should be using their iMac in such a way. If you are doing the test, try to align your eyes normally.
Be very sure that you are not observing any color difference. If you are observing any significant screen then make sure you give a call to Steve Jobs and ask for your share of 15%
