I use the adapter together with the "Belkin Mini DisplayPort to Mini DisplayPort cable". The MacBook Pro then goes for example on a Dell U3011 the full resolution of 2560x1600 pixels, without the expensive Apple Dual-Link DVI adapter. Total cost No 20. Does any problem and especially right away! The resolution means you do not get HDMI out, unfortunately, there is at 1920x1200 conclusion. The connection between the cable and monitor is stable and strong, because nothing wobbles. Already own a super inexpensive alternative to the Apple adapter he has the 5 star fully deserved!
