Same image on all monitors

8 replies

I have the same image on all monitors connected to a Lenovo ThinkPad x1 running Windows 10. Is there some configuration I am missing to get this to behave correct where each monitor is seem independently?

Hi Clarsat,
Going to need a bit more info ... you have a thinkpad X1 on win10, but how many screens are you trying to connect, which brand, which connection/cables ...

Hi I am connecting 3 Samsung 24 inch monitors connected via cable that is connected with DVI to monitor and HDMI to the Hub.  The monitor details are below:

24” SC450 Series LED Monitor Model Number: LS24C45KDSV/GO Serial Number: 3623P

so you are going from Mini-DP to CSV-5300H MST HUB and from the HUB with  HDMI to DVI Cable to the screens. Ok.
When the screens are recognized in Windows you should be able to set them to  "extend" in the windows properties. By the way are you sure the tablet supports 3 external screens ? I mean if the DP output is 1.2 you should have enough bandwidth but often laptops and Tablets have a restriction to the amount of screens they can feed. Mostly 3 in total (including its own). Please check

Ok is there an issue way to check this. I have three now running thru pluggable device for 2 and then a 3rd connect via secondary mini port.

What/Which pluggable device would that be  ?

Hi MST1407
i have the same issue, but running ubuntu 16.04 LTS. it's fresh installation with an AMD Firepro 8100 card installed. because of stability we dont use the AMD Linux Driver for the card. 
Because we need 5 Screens [in the end projectors] i bought the club3d MST [CSV-5300A]. 
So all Screens are there, but two, connected to the MST show the same image. 

I tried to find a possbility to split the screen but with no success.
The Option tp split in the Linux GraphicDriver is not present.

i hope you can give me a direction hwo to solve this.

Hello Matthias,

Ubuntu should support MST feature. If the system doens not allow you to send inidivudual video signals to the screens connected to the HUB, please check if the system does recognize those screens. If it does, but still no individual signals, then i am afriad you will need AMD Driver or other 3rd party software to "arrange" that.

Hi MST1407,
thanks for your answer. 
i had a look and the 5th screen is not shown. i used xandr.
it shows 4 screens and mirrors the 5th automaticly to the 4th.

so. you mentioned 3rd party software. do you have something in mind?
 at the moment i'm a bit out of options.

thanks again for your help.
