It's 2018 and still no 4k monitor with 120hz or 144hz support?

It can be pretty subtle, but unless a given video player has compensation it should be there. So if you watch 60fps content for instance on YouTube, that video will be smoother if you set your Hz to 120 or 60 than it will be if your set to 144hz.

That's not how adaptive sync panels work.
 
:lol: good point. I've never thought about how adaptive sync would work with something like a youtube video.
 
But if adaptive sync is active, it's no longer at 144hz. ;)

It would be at 60hz for 60fps content, etc.

Well, I guess the lack of judder I'm seeing must be a lie.

144 is not evenly divisible by 30 or 60.

With 24fps content there are 6 refreshes per frame so there is no pulldown/judder.

Got a video to share that will show judder at 144hz but not 120hz?
 
Any 30 or 60fps video will behave the same way. Try watching a scene where the camera pans. It will skip frames at regular intervals.

In fact, it's no different than 30 or 60fps in a game while locked at 144hz.
 
And its been exactly five years since my original post. I have forgot most of the technicalities that were originally posted, are there now good options?

I am looking for a monitor that is at least 27", preferably 32. It must be at least 4k native, must do 120 or 144hz at 4k with no compression, and better yet all that in 10 bit color, also with no compression. I understand it will require at least a 3000 series nVidia card with HDMI 2.1 support. I see that no card yet supports Display Port 2.0/2.1, they are all still DP 1.4a which doesn't have the bandwidth required to drive a monitor with my desired specs.

Looking at monitors, there are a number of them that seem to match the spec, but I'm afraid if they do some compression without announcing it in the specs.

Another thing that concerns me, I've been using Quadro cards, which only come with DP ports, and they are all still version 1.4, even the latest nvidia RTX A6000.
 
You can run 10 bit with DSC to my knowledge. Looks exactly the same. Quite a few monitors out now with 4K 144 Hz.

HU did a December update with all the known options.

Worth a watch on their channel.

Who is HU?
 
An issue to consider with 4K 120/144 Hz is it's still hard to actually run games at that resolution and frame rate. It still requires an absolute top of the line GPU in order to do it, and even then some games will not run at those frame rates maxed out.
 
I have started using DLDSR 4K and most games are pumping 120+ fps with a 4090. Which specific game are you referring to as I would like to test it out. I have always played with max graphics options.

I wonder what happens to 24fps movies when they are displayed on a 120 or 144hz monitors. On traditional 60hz displays they have jitter due to frame pull, but since 24 divides evenly into 120 and 144 there should be no jitter?
 
Never faced an issue. I have a 240 Hz monitor.
But then again I don’t watch movies on it. But I do watch tons of YouTube and it runs fine.

There is no pulldown on 120 or 144hz monitors. It will show the same frame for 5 refreshes @ 120hz, or 6 refreshes @ 144hz.

So that's a bit of a concern, the consensus is that movies look "cinematic" with the pulldown, and thats why they are being shot at 24fps instead of 30 or 60 fps.
 
Films being shot in 'cinematic 24fps' has nothing to do with pull down, they are two different things. You want to avoid pulldown. That's why TV's with a proper cinema mode play movies in a native 24hz (or multiple of 24hz).

Pulldown is a throwback from US NTSC broadcast days where TV is broadcast at 24fps @ 60hz which does not divide evenly, resulting in frames being held for 3 refreshes and then 2 refreshes, making it stutter or jitter. In PAL land (Europe, UK, Australia) video is broadcast at 25fps @ 50hz, so there is no pulldown.

I understand the difference between low 24fps movies are shot in, and the 3:2 pull down, but from what I am reading on various sources, the concensus is eliminating the pulldown is taking away from the cinematic experience caused by the jitter. I'm not too concerned with it as I barely even watch movies anymore.

On a side note, the 24fps is only for movies, right? What about regular TV broadcasts - news, sports, shows, etc?
