I have a Lenovo W541. On this system I have installed Fedora 23 At home this is connected to a Lenovo Ultradock, which is connected to an AOC monitor. This monitor supports a maximum resolution of 3840x2160.

I have however issues trying to display this resolution. The maximum I can get it to work at is 1920x1080. When I try to switch to a higher resolution the screen just turns black. This is what I see in the log. I switch to a higher resolution. Because the screen turns black I don't see the confirm dialog, and thus after a few seconds the screen reverts back:

Feb 12 06:36:46 me.kri.st /usr/libexec/gdm-x-session[2750]: (--) intel(0): HDMI max TMDS frequency 600000KHz

Feb 12 06:37:04 me.kri.st /usr/libexec/gdm-x-session[2750]: (--) intel(0): HDMI max TMDS frequency 600000KHz

Now this system has a quite powerfull graphic card. Two in fact:

kvanbesi@me etc]$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1100M] (rev a1)

I've installed the NVIDIA drivers from nvidia, and use bumblebee to switch between both cards on a per program bases. This actually works just fine, as long as I don't choose a resolution higher than 1920x1080. If I for example start a game with "primusrun <game>", and then within the game switch to a higher resolution the screen goes black again. Just like when I try this in gnome.

Output of xrandr (I'm using gnome + wayland at the moment)

File a bug report with nvidia as you are using a closed source driver - https://devtalk.nvidia.com/default/to...

So this is a bug, and not something I forgot to configure correctly?

Can you post your output of xrandr. It also looks like you have connected the monitor to the DisplayPort. Is it possible to connect it to the HDMI port?

does xrandr work with the nvidia driver ? last I looked it did not, you need to use the nvidia config tools.

For me xrandr did work, also with nvidia.

After reviewing the tech specs for your laptop and dock at Lenovo's website, the reason for the resolution limitation is as follows:

Though your attached monitor supports a resolution of 3840 x 2160, you will never achieve that resolution because the video board integrated into your laptop supports a maximum video resolution of 1920 x 1080. This is true for any manufacturer's chipset.

This is not correct. The graphics chipset in the laptop does support higher resolutions, and tthe docking station I use has compatible ports.

I have no issue getting 3840x2160@30hz with my old T410 (Intel).

It might be that the graphics chip is supporting a resolution of 3840x2160, but your dockingstation can only display a resolution of 2560x1600 when connected to the display port and a max resolution of 1920x1200 when connected to DVI or VGA. Did you try to connect the monitor directly to the notebook? If that is not working either, try to use xorg instead of Wayland.

I did some more tests. I think next I might try to see if I can get a thunderbolt dockinstation somewhere to test with.
