Screen turns completely pink after a few minutes

MacBookMax · 07-28-2013, 07:44 PM

I have now seen all kinds of colors including green.
Tried repairing permissions, as suggested in another thread in this forum, without success. The Displaylink-screen will still switch to a single color after a few minutes. Rebooting will help for a while.

The console log shows:
28.07.13 21:39:28,513 DisplayLinkUserAgent[4340]: CGSServiceForDisplayNumber: Invalid display 0x2b285990
28.07.13 21:39:28,513 DisplayLinkUserAgent[4340]: CGSGetDisplayBounds: Invalid display 0x2b285990
28.07.13 21:39:28,514 DisplayLinkUserAgent[4340]: CGSServiceForDisplayNumber: Invalid display 0x2b285990
28.07.13 21:39:28,514 DisplayLinkUserAgent[4340]: CGSGetNumberOfDisplayModes: Invalid display 0x2b285990

Any ideas from the Displaylink support team?

We have heard of the screen turning strange colours before, and this can be due to faulty DDR memory in the device.

If you are seeing this often, I would suggest returning the dock for a replacement.

Thanks Wim. The affected product is a Lindy USB to Displayport adapter. It was returned to Lindy, however, they say they can't find a problem.

I just received it back and again the screen will turn to a strange color after about 3 minutes.

I tried reinstalling the display link driver, repairing permissions and all that voodoo.
Could it be related to OS X 10.8.4? Any further idea?

Best regards

Max
