34" display on Intel HD P4600

Hi,

I'm trying to use my Dell 3415 at 3440x1440 using the Intel HD P4600 (Xeon E3-1225 v3). According to the Intel spec sheet this resolution is supported via displayport. xrandr shows the right resolution but as soon as I switch to it the display goes blank.

xrandr Output:

Screen 0: minimum 8 x 8, current 2560 x 1440, maximum 32767 x 32767
DP1 disconnected (normal left inverted right x axis y axis)
DP1-1 disconnected (normal left inverted right x axis y axis)

Linux T20 4.0.7-2-ARCH #1 SMP PREEMPT Tue Jun 30 07:50:21 UTC 2015 x86_64 GNU/Linux

Any ideas?

E: It works for 50Hz.

Re: 34" display on Intel HD P4600

I bet it works with 58.97 Hz, according to your xrandr output. The resolutions are usually reported by the display, so it seems your display is fine with that refresh rate. I just wouldn't want to play a console game like that, the tearing might be weird.
