Just got myself the Sparkle X-LINK USB/DVI adapter for my iMac. I have a three screen setup. Running snow leopard and the Beta 1.53b driver, when I reboot my machine or switch on the next day, the system boots into snow leopard but the third screen connected with the X-LINK, doesn't hold its colour calibration. I have to constantly go into the display properties and click on the calibration profile to correct the colours. The screen in a 19" in portrait mode running 1440x900. When I click on the correct profile after booting, the screen is fine until the next time I reboot. The colour distortion seems to change my RED to GREEN on the third monitor.
I have tried the 1.51 drivers aswell with no luck
