Hi, I'm currently using a MBP 13", and a monoprice mini-DP to DVI adapter. It worked fine for other monitors, and I'm currently trying to use it on my 22" LCD monitor --- Philips 220SW9. However, my monitor is unable to detect any video input, even though the monitor shows up under "Display Preferences." The monitor works when I tried to use it with an older Macbook and an Apple mini-DVI to DVI adapter. I'm writing to see if anybody has had any experiences with this problem. Thank you for your time.
