I'm considering a Philips BDM4065UC monitor. It is the only 40" 3840x2160 screen with DisplayPort that I know of. It seems ideal for getting more screen work space as it has a similar pixel pitch to a 27" 2560x1440 monitor. Has anyone tried it? Do you get the full resolution at 60Hz when connected by DisplayPort? I'm looking at using it with a 15" rMBP.
