I have installed Ubuntu 16.04 on my Dell Precision 5510 laptop but looks like the graphics driver for its discrete nVidia Quadro M1000M is not installed/configured properly such that it can't playback a couple of 4K videos that I've downloaded at 60Hz. The built-in video player plays them more like 1 frame every 10 seconds or so.

lspci shows the following devices:

$ lspci | grep -E "VGA|3D" 00:02.0 VGA compatible controller: Intel Corporation Device 191d (rev 06) 01:00.0 3D controller: NVIDIA Corporation GM107GLM [Quadro M1000M] (rev a2)

ubuntu-drivers devices shows the following output:

I have also installed the nvidia-361 drivers:

However looks like its kernel module is not getting loaded:

The videos I have downloaded are:

Is there anything else I need to do in order to enable the full potential of the nVidia graphics card? Also Skylake mobile Xeon CPUs have integrated GPUs that can play 4K video at 60Hz with no problem at all. However as mentioned earlier at the moment I cannot render 4K video flicker-free and it renders more like 0.1 frames per second.
