While i have nil experience with Intel Mini's, i had that dance with a PPC unit. While monitor resolution was within Apples spec when it opened into a non standard Apple resolution it worked on first set up but when restarting it could not find the resolution and remained blank. Even with SwitchRes the higher resolution never worked reliably. Once it failed in the higher resolution the problem was resetting back to a lower resolution - i ended up using 2 monitors - a smaller Apple to do the reset and then try again to get it to do the higher Philips resolution. End result - gave up.
