I have also read through many posts on Intel, these 8 pages included...I have also installed, and re-installed the driver for the video. It works, but not if I have to restart the computer. Or if the computer restarts itself after an update or whatever. I have the newest drivers installed...is there any reason they are not working once the computer restarts? If I re-install the video driver, it works, until the next restart. I've had this computer for about a year, and only just now added the second monitor...a ViewSonic VG2230...using a DVI to HDMI cable.
I'm hoping there's a simple solution to something working, and then not working, once there is a restart.
This is the driver I'm working with:
