Hi, just received my 20" ACD and there are 3 things I can't understand. My ACD is connected to my MBP and used as primary display. 1) What's the minimum brightness setting like ? Doesn't it go completely black like my MBP ? I'm at minimum brightness settings and it is still very bright. Is this normal ? 2)I tried to connect my LaCie external drive to the ACD hub and it doesn't work, while iPod and other USB devices are ok. No problems thru FW. Why ? 3) Is it possible to keep the MBP lid slighly open while using the ACD as main monitor? 4) I discovered that I can do point 3 by simply opening the display after the main monitor is on. However if I do this, if the MBP goes to sleep, after wakeup the dock and menubar disappears from the ACD while the MPB shows nothing. Is there a way to avoid this ?
