4k, judder, etc...
Boltron:
0 dropped frames and visible judder is a strong indicator of refresh rate mismatch. Do you use receiver? If so it will most likely have a screen where you can check the TV reported capabilities (1080p 24 fps, 720p 60 fps etc...) ad the incoming PC signal.

No receiver...
Honestly it's not a big deal as long as it is not the TV.
mwillems:
Have you explored the TV's configuration settings in detail? I had a large Samsung screen that had ugly visible judder, until I found a setting called something like "display motion" or "auto motion" and changed it to "clear." Literally every other option under that setting produced results that were either smeared or juddery. It's some sort of motion smoothing gimmick, and several other manufacturers have similar settings (LG does as I recall).
I'm not an expert, but it's worth a look.

The TV has smooth motion, and clear action. Smooth motion gives it the 'soap opera' effect, although, I only tried it on the low setting. Clear action is either on or off, but neither seems to make a difference.
It doesn't appear to be an interlaced/non-interlaced issue. I have an episode of TV that RO HQ says is not interlaced, but is 1280x720 resolution (although RO HQ says it is slightly lower than that), but that episode always shows the jitter, so I tend to use it to test with. On Elementary last night, I barely noticed it, and it was 1920x1080.
I am wondering now if it's not worse on lower resolutions. I have some compressed videos that are 854x480 that I am going to test.
muzicman0:
So now I am more confused than ever...the SAME episode that I had ran through handbrake, and converted to 854x480 29.97 FPS has no issues, or if any, I didn't notice them.
What I did find interesting is that that episode, using Cntrl-J, showed as the correct resolution, but the original episode (before I ran it through handbrake) shows as lower than 1280x720, it was something like 1223x684 or similar...do you know why it did that?
