I have a 4k 60hz monitor that I hooked up to the Librem 13. The max resolution option that I see is 1920x1080.
How do I change the resolution to 4k? I have 3 other laptops that can output to this monitor at 4k 60hz. Is this 1920x1080 resolution a limitation because this machine is not using proprietary drivers? From the little reading I did, the Skylake iGPU should be able to output 4k.
