I know there are people in these forums who have an Apple LED Cinema Display hooked up to a PC with a Mini-DP to DVI converter. My question is, how do you guys adjust the brightness of the display? Is it always just left at max brightness? Does the LED Cinema retain the display brightness of the last time it was used... for example, if I hooked up a Macbook Pro to it first, turn the brightness down to halfway, and then hooked up my PC, would the brightness then be at half instead of full? Also, is there any way to get the USB sound to work with a PC? Thanks in advance!
