I installed maverick on the t410s based on instruction on this website and everything works fine. However, I am using a 27" crossover LCD as external monitor connected to the T410s docking station's Display Port. If boot the t410s, initially the external monitor will be able to show the darwin boot HDD options and the initial screen of OSX booting. However, when it comes to the pint of inputting the password, the external monitor screen goes black and I can see the Display Port got no signal. Is there any way t enable external monitor? Thanks!
