Hey Guys, I've had a quick search of the threads but can't find any information that exactly relates to my question. Maybe someone will be able to answer this for me... I have a bog-standard 24" iMac C2D and have it hooked up to my 23" ACD (looks very cool by the way). However, I'm wondering if this setup actually decreases performance in anyway! I seem to be witnessing a bit of slowdown when I run applications, or when I drag windows about (like a stuttering in the movement). I'm positive this wasn't the case when I first got the iMac and didn't have the 23" ACD hooked up to it. Can anyone answer this from a technical perspective? Any advice would be greatly appreciated. Thanks.. and Happy New Year to you All.
