- Lenovo ThinkPad T430
- Windows 8.1 Enterprise, 64-bit
- Lenovo ThinkPad Mini Dock Plus Series 3, Type 4338
- 3 external monitors of various types and resolutions (Dell, HP & Acer)
Description:
The Lenovo ThinkPad Mini Dock has 1 VGA output and 2 pairs of DVI-D/DisplayPort. The documentation says it can be setup in a Quad Display Configuration. (See http://support.lenovo.com/us/en/documents/ht037605)
For quite a while, I have been using it in a dual display configuration, with each of the following:
1 external Monitor:
- 1 monitor on VGA
- 1 monitor on DVI-D
- 1 monitor on DisplayPort
Recently, I moved offices, and now have some extra room, so I have tried several new configurations:
2 external Monitors:
- 1 monitor on VGA + 1 on DVI-D
- 1 monitor on VGA + 1 on DisplayPort
- 1 monitor on each of DVI-D
3 external Monitors:
- 1 monitor on VGA, + 1 on each DVI-D
- 1 monitor on VGA, +1 on DVI-D + 1 on DisplayPort
In each of these cases, I get the same result:
- In the "Screen Resolution" dialog, when I hit the [Detect] button, all monitors show up, and the description in the Display combobox is correct.
- If I Extend the desktop to any single external monitor, it works fine. (Drivers, cables, etc. are all good.)
- If I attempt to enable any other display (extend or duplicate the desktop) it looks good on the dialog until I hit [Apply]
- When I hit [Apply] I see a dialog that says: "The display settings could not be saved. Please try a different combination of display settings."
Question:
Does Windows 8.1 Enterprise 64-bit support more than 2 displays at a time?
- If not, why does it detect all of them and let me enable everything until I get to the [Apply] button.
- If so, what am I doing wrong? What can I try next?
