Daisy chaining issues

[jp1987]

I've bought 2 Dell U2414H screens and daisy chained them to my laptop using the mini display. I had to upgrade the kernel to 4.1.6 and Ubuntu to 15.04 before the daisy chain worked (mirrorring worked fine, but not extending).

So right now I disabled the laptop screen and am running 2 external screens. Sadly the 2nd screen (the one that is daisy chained) has screen tearing when I run it on the highest resolution (1920x1080). When I set it to 1600x900, it works fine. Obviously I really want to use a high resolution on this screen as well.

Any ideas? I've tried to update all the Intel drivers and set the TearFree option to true. No luck.

It works fine on a Windows laptop so the screen and cables seem fine.

👍 Same displays, same setup, same tearing and occasional black outs
