This is very frustrating, and disapointing.. all day I was looking forward to hooking up the 23" so i can do what i do on something other than this tiny 13" screen. Both monitors I have require the ADC power supply, I then went with the thunderbolt port out to DVI, and then the ADC power supply has ADC connection for display and DVI for the adapter. The little light on the monitors fade in and out, USB peripherals work, but other than that, nothing is being detected. Anyone else have any idea what could be wrong? Both monitors were working just fine together an hour ago on my G5. I DID purchase the adapter from ebay for like 6 bucks but seriously, what are the chances.. I know this laptop just came out a few days ago, but maybe theres more people with similar problems.. im open to any and all suggestions and appreciate them greatly, thanks.
