I have my late 2008 Macbook Pro hooked up to a 24" Dell E248WFP Display via VGA. The display sporadically turns off, saying: Auto Detect (Analog Input) Power Save Mode It then turns itself back on a few seconds later. For what it's worth, this is exactly the same screen I'd get when I put my old HP laptop to sleep. I've played with the energy saver preferences on my Macbook, and there doesn't seem to be any power management options in the monitor's menu. What's my play here? I've called Dell, but there support is just awful. They kept asking me for my Express Service Code, which I don't have. Then they hung up.
