I have a t410S from Lenovo and when I try to use a second monitor so that I have 2 monitors and my laptop is not one of them. I cloase the laptop and it sees the one monitor but not the other. I have all the correct drivers as Lenovo has remoted into the box. They seem to think this is a limitation of XP on their new laptops. I used a Display Port to single - link DVI and it works fine. I am not sure why KLenovo cannot get it to work without the workaround?
