I have two external monitors: Asus and ViewSonic. I have a miniDP to DP cable to use the Asus as a display with the Surface Book, and this monitor works fine either directly connected or connected through the Surface Dock. I also have a miniDP to DVI cable
to use the ViewSonic as a display with the Surface Book and this monitor works fine when directly connected from the Surface Book to the ViewSonic. It does not work through the Surface Dock using the very same miniDP to DVI cable that works when directly connecting.
So, I'm trying to connect the Surface Book through the Surface Dock to the ViewSonic. Most of the time, I receive a blinking screen on the ViewSonic; the extended desktop comes on and shuts off about once a second. Sometimes it displays a thin vertical column
centered on the screen which is a portion of the desktop it should be displaying. So, it's not working but at least the signal isn't random noise.
I tried a Pluggable Mini DisplayPort to HDMI Active Adapter, and I happen to have a BlueRigger HDMI to DVI cable that I know works. If I go to Desktop->DisplaySettings->(SelectMonitor2)->AdvancedDisplaySettings->DisplayAdapterProperties->Adapter->ListAllModes
and select a Resolution, Color Depth and Frequency where the Frequency is something other than 60 Hertz, it works. But, not all Resolutions and Color Depths are available at Frequencies other than 60 Hertz. So instead of "1600 by 1200", the best resolution
I can select is "1280 by 1024". Ironically, the ViewSonic monitor itself puts up a message when I connect at "1280 by 1024" saying "Resolution Notice: For best picture quality, change resolution to 1600 by 1200". Thanks.
I can get "1600 by 1200" resolution and 60 Hertz fine, through either the miniDP to DVI cable or the Pluggable Active Adapter to BlueRigger HDMI to DVI cable combination, if I don't use the Surface Dock.
I did see a grayed out option at Desktop->DisplaySettings->(SelectMonitor2)->AdvancedDisplaySettings->DisplayAdapterProperties->Monitor for "Hide modes that this monitor cannot display: Clearing this check box allows you to select display modes that this
monitor cannot display correctly. This may lead to an unusable display and/or damaged hardware". I note that this box is not checked, and because it's grayed out, I cannot check it.

Surface Dock miniDP doesn't work to DVI even with Active Adapter at 60 Hertz
