Hi Matt
do you have a photo?
Is it like white noise - or the desktop - but broken up?
Have you tried a different LCD?
or a different graphics card?
What OS version are you using?
One thought:
Apple have changed the way they handle HDCP in Snow Leopard - and some older LCD are either not HDCP compliant, or don't seem to display the image correctly.
I have some benQ G2400 that are over 2 years old and are problematic. Wheras the new BenQ G2220HD and E2220HD work fine...
A DVI Detective or Parrot with a custom EDID may help as it will stop the HDCP - if thats the issues here?
From your notes - DVI out 2 to ImagePro, from loop thru to Samsung Sync Master E1920 Monitor
This may be a clash of EDID with the ImagePro and LCD connected to it. Its a common issue with ImagePros.
It can usually be fixed by removing the LCD and allowing the imagePro to send its EDID.
Best option is to connect a DVI DA directly to the Mac and then the ImagePro and LCD to the DA. (you may have to install a DVI Detective or Parrot in there too....)
The reason you are getting an offset is probably due to the ImagePro EDID. It is possible to set a custom EDID on an imagePRO - but you have to have the latest firmware as there is a bug...
(will update with details later)
It might also be wise to try a different graphics card and see if the problems persists.
