I've yet to find a monitor that "just works" with my MBP. I'll take whatever they release. My LG is nice, but often gets confused about when my laptop is plugged in. Both of my Dells are ok, but randomly lose signal and can't control the volume from the Apple keyboard or from the OS. It would also be nice to not need a docking station and or adapter anymore.
The fix for me was to use DisplayPort, if HDMI was in the mix it would have the reliability of a 90s monitor.
