I received my two new Dell UltraSharp 24" ( U2414H ) monitors today to be attached to my Microsoft Surface Pro 2 ( 512Gb / 8MB ) and docking station. I ordered these monitors because they are designed to use in a display port daisy chain arrangement. So I set them up as following, plugged micro-display port into the Surface Pro 2 dock then plugged the other end of the cable with the full sized display port into the display port ( IN ) port on monitor one ( 1 ) and then plugged another display port cable into monitor one ( 1 ) display port ( OUT ) then into monitor two ( 2 ) display port ( IN ). Both monitors display beautifully, but not as I was expecting.
I feel like I am missing something here but don't know where to start. I was expecting the display settings in control panel to show three ( 3 ) displays, the Surface Pro 2 display and the 2 Dell external displays. But what I am seeing is the Surface Pro 2 display and the 2 Dell U2414H monitors as a single display. What I wanted to do duplicate the start screen on the first Dell U241H monitor and then extend the desktop to the second Dell U2414H monitor. But I can not see how to make this all work. Has anyone daisy chained 2 external monitors like this and if so how did you get them setup correctly? Is there something that I need to set on the second monitor in the daisy chain to make Windows see it as a third display panel?
So can someone help me please...
Here is an update that I have discovered. On these U2414H monitors the display ports default to DP 1.1a and you have to enable DP 1.2 to get the additional functionality. Which does allow me to use the two Dell monitors as I wanted. That is Windows 8.1 Start screen on monitor 1 and the desktop extended to monitor 2. But with that all working the Surface Pro 2 display is now disabled and black until you undock the tablet. I guess I give up for tonight, I am frustrated and tired working with this issue. Will see if anyone else has any recommendations.
I'm having the exact same problem with the pair of U2414H monitors I just received the other day. Here is my setup:
NVidia GTX680M graphics card (The laptop has this and an onboard Intel, the BIOS does not have an option to switch to only using the NVidia card. It will only do hybrid graphics). Latest NVidia driver.
Monitor driver date 11/26/2013 (latest)
Dell has no updated firmware for these monitors on their site
My laptop is connected to the mini DP input of monitor 1. There is another cable from DP output on monitor 1 to DP input on monitor 2. Both cables are confirmed to support DP 1.2.
While I can get a display on both monitors with this configuration, Windows 7 only sees one external monitor. The output to the DP output is mirrored on both monitors. I can extend the Windows desktop over the laptop display and the external output, or I can only send the Windows desktop to the external port. In either case, both external monitors show the same mirrored screen.
What I really want to do is to have each monitor have different displays, and have Windows extend over both of them. I was hoping that the NVidia driver I just installed today would fix this, but no luck. This happened with the previous driver version as well.
I'm hoping Dell responds soon.
I was able to get this working. In the menu on the first monitor in the array I had to enable displayport 1.2 in the monitor menu. It was disabled by default. Once I enabled that I could get all three monitors, two U2414H's and the surface pro's display, working.
