I recently purchased an HP 2159M Monitor to go along with my Macbook Pro. I also purchased a mini displayport to HDMI adaptor from monoprice, and an HDMI cable to run from the adaptor to the monitor. When I turned the monitor on and connected it to the MBP, the MBP's screen flashed baby blue for a second, but the HP monitor stayed blank. Going into system preferences/displays, it seems my Macbook Pro doesn't recognize the monitor, and hitting detect displays does nothing. Thinking maybe a driver might fix the problem, I went to HP's site, and there are no OS X drivers for this monitor. Going into their support chat, all I got out of them was, we don't have drivers; you should talk to the store you bought the monitor from. I've never in my life heard of a monitor not working on Mac, and before buying I did do research - several people on this forum, apple's discussion forum, and others who use macs all report loving this monitor and recommending it. Oh, and my screen still randomly flashes baby blue for a second and fades out when connected. What gives?
