Open the attached GIF images in full screen (the thumbnails won't be so obvious)





If you are viewing this on a TN film based panel the colours will change depending on your vertical viewing angle.



- Purple:

From below, the colour will be close to pure blue

From above, it will appear a washed out bright purple







- Green:

From below will be close to dark green

From above a washed out bright yellow







- Cyan:

From below will be almost pure blue

From above almost turquoise







- Grey:

From below will look black

From above white







If you are NOT getting these distortions, you do NOT have a TN film based panel - it will either be S-IPS or S-PVA.





Again, open the attached GIF images in full screen (the thumbnails won't be so obvious)



Let us know what results you are getting and which Mac you have.



Thanks for participating!





NOTE: All notebooks will produce this side effect as they all use TN Film panels. This is normal.

    The moral of the story: Don't look at your screen from way above or below it. Look at it...straight on!

    I'd like to think the moral is:



    Don't rely on TN Film for accurate colour reproduction on critical applications, such as semi/pro photography work.



    Buy a 24" iMac over a 20" if colour accuracy is important to you.



    Take the test, know what you are dealing with. Knowledge is power. etc...

    Well, then you have the "glossy" issue.

    Cheers for that - although probably not a good idea to test from a lossy JPEG file.



    Here's a couple in PNG format:
