Unless you have actually two monitors connected, that's a kernel bug. > Problem is that the > display comes up with a low resolution.

You might want to test different kernels on your Jessie machine, e.g. the 3.2 Wheezy kernel or the 4.1 Stretch kernel. > I'm apparently using DVI-I-1, but highest available resolution is not > being selected.
