It's probably best you start a new thread, this thread is about a whole 
different issue altogether. 

But since this is an old thread, I'll briefly answer you. 
This what you seek, directing a GPU directly into an AppVM, or any other work 
arounds, can currently be done in Qubes 3.2. nor Qubes 4.0. 

However, it is planned for Qubes 4.1, which may reach release. Just don't get 
hyped yet, things can change, 4.0. is barely finished and 4.1. is currently 
only on the drawing board. Look here for quick information about 4.1. 
https://github.com/rootkovska/qubes-roadmap you can see the GTX passthrough 
ability on the map.

Also, you don't really need Ubuntu for these kind of things, it can easily be 
fixed up in both Debian and Fedora. You can use Intel graphics just fine for 4k 
videos, you don't need nvidia for stuff like that on modern motherboard/CPU 
systems. You may need powerful graphic cards for gaming and high end graphics, 
but this too isn't possible, at least before Qubes 4.1. anyway. If you didn't 
need these in Qubes 4, then it will likely make no difference to you to use 
Intel graphics. Also Qubes dom0 frequently has nvidia graphic issues and may 
require a full properitary driver download/install, with a manual install. 

To get a bit back on-topic, it saves you whole lot of hassle if you get 
adjusted to not be depending too much on Ubuntu and others that give everything 
on a silverplate. Although DVM protected content is never stable regardless of 
the Linux distribution, unless you download the Google Chrome browser from 
Google (Not Chromium), which usually always have working DVM videos in any 
Linux. Issue being, that Firefox and others, often loose the ability to play 
the video, especially Microsoft silverlight videos, which the work-arounds 
frequently break.

Essentially you can play the codecs fine, HTML5 is for example extremely easy 
to install in Fedora through enabling the RPMFusion repositories, which can 
easily be done in Qubes fedora template (best make a copy first). But it does 
not include HTML5-DVM. 

Essentially, DVM is so messed up, you may just want to download the Google 
Browser specifically for these videos, and just be done with the crapware 
copyright protectors throw at us. It's not like they care about Linux anyway, 
so why would changing to Ubuntu make any difference? Ubuntu is just as unstable 
in this regard of protected content due to lack of developer support of 
protected contents.

However, Fedora+Firefox+RPMFusionRepositories+ffmpeg+Firefox's own DVM = 
Netflix and all HTML5 videos on youtube, and similar modern websites, works 
smoothly without issues.

Try not to get too dependent on a system, really it makes little difference if 
you adjust yourself to it.

Also install Qubes with LegacyBIOS/Grub and press the E key during the Grub 
menu, then add after or before "quiet" on the module code-line. Or just 
temporarily disable nvidia in your UEFI, works too, more or less does the same 
as nouveau.modeset=0.
