Adobe Reader doesn't open in 3840x1200 resolution

Hello all, 

I saw in the threads that a lot of people complaned about Adobe Reader not opening PDFs. Same thing happens to me but only when i am conected to my external monitor. It's 32:10 3840x1200 screen, Samsung 89J430. When i disconnect the thunderbolt cable and try to open it on my Laptop (X1 Yoga 3gen) on it's 4k display it works fine, If i then connect it back to my external monitor i can use it untill i close it. If so, i would have to disconnect it and to the whole procedure again.

Is there a fix for this? It seams to me it's a resolution or ratio problem.

What exactly happens if you try to open Reader with the Samsung monitor connected?

Nothing happens, the desktop just refreshes and the application doesn't load.

These are the apps that run in the background. It doesn't matter if i end the processes or not, after disconnecting, now, i cannot start the Adobe Reader. I have to restart the laptop with out the monitor connecter, run the app and then connect it.
