I have a IIYama screen that curerntly display garbages (very, very poor quality).

On the IIYama website, I found drivers for my screen (ProLite B2409HDS), it contains the following files:

  • 2409hds.cat
  • 2409HDS.icm
  • 2409HDS.inf

And some other files for Windows 7.

But my issue is, on my Display preferences, I can't see any button to add a new profile using my icm file :

enter image description here

If I click on Open profile, I get a ColorSync profile that looks like when I open the given 2409HDS.icm file manually, so I think there is a way to add it... But can't find it!

Any suggestion ?

  • Care to elaborate on what problem you're having with the display? Take a photo of it.

I finally found how to add profile: put the icm file on that directory:

Macintosh HD\Library\ColorSync\Profiles

And you'll see your profile here....

Anyway, this did not solved my issue, it looks like Apple really want us to buy their incredibly expensive screens. I surely regrets paying 30 boxes to upgrade to 10.8.

  • Well, I have an ASUS and it displays correctly...

  • I think .icm files are in a proprietary Windows-specific format, and won't work with OS X.

  • @SilverWolf, it worked for me. But incorrectly ) colors were absolutely wrong and orange. Usually I make the profile derived from the default sRGB one (at the very bottom of default profiles) but it's sill hard to calibrate by looking at dithered fillings on Retina.
