Problem with 2 screens on Surface Pro 2

8 replies

Hi everybody,

I have a Microsoft Surface Pro 2 and I try to connect 2 screen (2 HP LA2205wg) with display port. So I bought Mini DisplayPort to DisplayPort (CAC-1110) and a MST Hub DisplayPort 1-2 (CSV-5200).
When I connect all, my 2 screen HP display the same. It's not an extended Desktop.
In display property, I have only 2 screens : Surface screen and just one HP.
My chipset graphic driver is updated. I don't understand.
Can you help me?
Thanks a lot.

Hi Flav,
We have a SP2 here so i will try and duplicate the setup.
A CSV-5200 + CAC-1110 work together that has been tested.
What OS are you on and what graphics driver and /or graphics control panel verison ?

My graphic driver is updated. The version is 10.18.10.4358.

Hi Flav
Sorry for the delay, but were back online :-)
I will try it out here. You also have Graphics Control Panel installed ?

can you also please check with HP if those screens are compatible with MST functionality ?

Hi,
Yes I have installed Graphics Control Panel. The last version. 
I will verify for HP screens.

HP LA2205wg have display port 1.2, so I think it is compatible. 
In the specifications of your product, you do not give the list of compatible screens. 
I test also with 2 screen Lenovo and doesn't work also. 
I am really disappointed.I think to return the product for refund

Hi Flav,
I just tested on our SP2, we have WIN10 running on that and driver version 10.18.15.4256.
Plugged in the CSV-5200, first the USB then the DP with CAC-1110 to the Mini-DP out.
Connected Sumsung 23"1080p 60Hz screens (from our EF6 setup) really very standard and common screens, and running like a charm! I Did not have to do anything ... here's alink to the video i made with my phone. Sorry for the poor quality but not easy to connect the CSV-5200 and 2 screens while holding your phone :-S

and yes you are right we do not have a listing of compatible screens, sorry about that. However normally screens with DP1.2 input also support MST functionality ... only very rarely they do not. From the thousands of MST Hubs we sold i only encountered that 2 times so far ... 3 times now if that would b the issue you are having.
Anyway what OS are you running ?
