I have a Lenovo w530 laptop running Windows 7 Professional 64bit which cannot see my Viewsonic VG2030wm monitor, no matter what driver is installed. I contacted Viewsonic support who sent me links to drivers for Windows 7 Vista and XP-64, neither of which resolved the issue. Does anyone have a driver that will allow my new laptop to see my external monitor? Thanks!
check out this PDF link I found and go to page 37. Looks like you need to do 2 things. #1. Switch to Discrete Graphics in the BIOS #2. Once you are in Windows press the Fn key + F7 to toggle between the different "external monitor/projector" modes. Here are the links I found, read number 2 on this first link - http://blog.pearce.org.nz/2012/08/enabling-external-monitor-on-lenovo.html and then go to page 37 of this PDF on this link http://www.lenovo.com/shop/americas/content/user_guides/t530_w530_ug_en.pdf
