With kernel 4.13 and older, I can use a resolution of 2560x1440. But, since the upgrade to kernel 4.15, I'm limited to the 1920x1200. I have attached the output of xrandr on both kernel. My screen (Dell U2713HM) is plugged to the output DVI-1. With a kernel 4.13, the output is detected as a DVI-I. But with a kernel 4.15, the output is detected as a DVI-D.
