The TV’s the Rokus are connected to are not UHD.  I don’t think the Rokus can down sample and tone map UHD.  We are talking lots of Rokus, multiple family member households. And users who don’t want to change stuff on their end and/or I have to be the person that sets it all up.

If the Rokus are relatively recent, there is no issue. Tone mapping is abandoned if the TV doesn’t support it. You can play UHD material on a non-UHD TV without any issue. It simply ignores the UHD information.

 

 If the Roku reports as a client that doesn’t support 4K, then you will have to transcode.

I'll have to check.  They are all Ultra's because I insist on wired connections whenever possible.  They are at least three or four years old at this point.  My mom alone has five of them.  Then my three siblings and a couple friends.  I use ShieldTV in my house because they can handle EVERYTHING on their end and I have four for me and the family, but all but one of my own TV's are UHD (kitchen is still old).  The rest of my family is not tech savvy, at least not in this area so Roku works well for them (I'm not customizing and maintaining like ten more ShieldTV's).  I run custom launchers on my Shields which greatly reduces complexity; my then six-year-old daughter couldn't use the TV, but with my own home brew interface design she literally learned to work it in less than five minutes.

 

My Shield interface.  This is what you see on my TV's and projector when the Shields boot (home screen):

 

 

No garbage in the way.  Could it be easier?  I really hope there is a Shield 2.

 

I've derailed my own thread, but at this point it doesn't matter I guess.

Back on topic.  With my Intel E-2288G, before I had four cores (eight threads) isolated for VM's (usually just Windows these days, sometimes Ubuntu) and only three cores (six thread) pinned for dockers.  I changed this around and have improved performance substantially for actual real-world use.  I un-isolated two cores (four threads) for my VM's.  That left two cores (four threads) isolated for VM's.  Then I pinned six cores (12 threads) for VM's.  I then also pinned five cores (ten threads) for dockers.  Windows is faster as the dockers don't often need a lot of power; PLEX when it's analyzing shows for library, commercials, intros, and NZBGet when it's downloading, repairing, and decompressing.  NZBGet now maxes out all ten threads and gets done MUCH faster.  Windows is a lot more zippy.  This is where I am now.  In any event, I think I squeezed another year or two easily out of my current setup.
