Three independent monitors on DZ87KLT-75K?

[AONym]

The Intel motherboard?motherboard has an HDMI connector for a monitor, and also a Thunderbolt connector. I am successfully using two independent monitors with Windows 8.1 by connecting one via HDMI and the second using a MiniDisplay port to DVI adapter + DVI cable to the monitor.

I want to add a third monitor, which the spec says is supported. All three monitors should have independent contents (extended desktop), although they will all have the same resolution.

What hardware do I need to accomplish this? Is there some adapter that converts the Thunderbolt connector to two independent DVI ports? Or do I have to add a video card?

Hello VirtualMemory, I will be more than glad to assist you on your inquire, however I will need to get additional information.

According to the product documentation of this board, it only comes with 1 HDMI port. You are saying that you are using a second monitor connected to a Mini Display port, would you mind send me a picture of this set up?

Could you please verify the model number of the board?

In order to have triple display on the DZ87KLT, you would need to add 2 video cards. One of them needs to have 2 video ports.

For a picture, see "Intel Desktop Board DZ87KLT-75K Technical Product Specification", Figure 12; Thunderbolt connector is Q. The Thunderbolt connector provides the MiniDisplayPort. I am using a MDP-to-DVI adapter connected to Q.

Also see sections 1.3.1.5 and 1.9.2 in the spec. This is the only information I could find on connecting multiple independent monitors.

VirtualMemory, in every three multi monitor configuration is display port is required. In this case you are using an HDMI and a thunderbolt port, and you are converting this to a mini display port to DVI.

It is working on dual monitor configuration because you are converting the thunderbolt to DP which is digital signal.

This document lists many of the possible ways to connect a computer to three displays and the ways to optimize your viewing experience.

I had already seen all the documents you referenced--they don't answer my question. This is my question: What physical devices do I need, and how should they be connected, to get three independent monitors?

This is clearly incorrect.

Please refer this question to someone who is more familiar with the DZ87KLT-75K and the Thunderbolt technology.

I don't see how triple independent display is possible by using the outputs of the DZ87KLT-75K alone. The HDMI connection supports a single display, and the Thunderbolt connection (DSL3310: http://ark.intel.com/products/67022/Intel-DSL3310-Thunderbolt-Controller http://ark.intel.com/products/67022/Intel-DSL3310-Thunderbolt-Controller ) supports DisplayPort v1.1a, which is only capable of a single output, or a spanned / extended / cloned desktop over multiple displays by using a DisplayPort v1.1 hub:

If you look at the Dual / Triple display configurations for the Intel NUC series, the Intel DC3217BY contains the same Thunderbolt controller as well as the same video (HDMI v1.4a) / Thunderbolt outputs, and is only capable of dual display according to this chart: http://www.intel.com/support/motherboards/desktop/sb/CS-034199.htm http://www.intel.com/support/motherboards/desktop/sb/CS-034199.htm

Table 3 here: http://downloadmirror.intel.com/22677/eng/DZ87KLT-75K_TechProdSpec02.pdf http://downloadmirror.intel.com/22677/eng/DZ87KLT-75K_TechProdSpec02.pdf suggests that you could use the onboard HDMI connection in addition to a video card of your choice to enable multiple independent displays.

Sections 1.3.1.5 and 1.9.2 in the spec clearly say the board supports three independent monitors. Presumably, two will be via the Thunderbolt connector, but I don't know how to do this.

Also refer to the tables sylvia_intel showed (these are from the spec).
