Question All video players stutter or display lower framerate through HDMI cable on TV ?

[Rostropovich]

Hi,
So, I've been having a really strange issue lately. I have an 48Gbps HDMI cable running from my PC to my Samsung "The Frame " 2019 model TV, that I'm using in duplicate display mode in Windows 11.
Everything works perfectly, videos that are in the browser, video games and everything else runs great without any issues.

The only issue that I'm having is when I want to watch a movie or show or any other video file from a video player on the computer, the video is choppy and in low framerate, perhaps it even looks like it's losing frames. I didn't have this issue in the past. I tried changing the display mode to display only on the TV or to change video players, change the refresh rate and nothing seems to work, the image is still choppy.

I'm honestly at a loss with this one and have no idea what else I could try so any suggestion would be welcome, because it makes video files unwatchable because the choppiness is really distracting.

The video players that I've tried are MPC-HC, VLC and PotPlayer and I assume the issue is present in every player.
I've swapped the cable with another one and the issue persists with another cable too but I have no other monitor or display to swap around as I only have one monitor and TV.
My disk drive is a 2TB WD_BLACK SN850X NVMe SSD with heatsink, less than 6 months old, currently with 1TB free space.
PSU is Seasonic Vertex PX 1000W, less than six months old, new model.
The issue started a month or so ago and everything was working correctly on this config before that.

Full PC build specs:
Mobo: ASUS ROG STRIX Z790-F
CPU: Intel Core i7-13700K
GPU: Gigabyte RTX 4070 Ti
RAM: Corsair DDR5 32GB @ 3600MHz
SSD: WD_BLACK SN850X NVMe 2TB
PSU: Seasonic Vertex PX 1000W
Case: Fractal Design North

Update your post to include full system hardware specs and full OS information.

PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

What video player(s)?

Do you have another known working (no choppiness) HDMI cable to swap in?

Any ways to swap monitors etc. about to determine if the problem follows the monitor/TV or stays with the computer?

Thanks for the suggestions. Done as requested.

Include all specs in the post. Not everyone has signatures enabled.

One thing that you can do is to take a look at what the system is doing or trying to do when the video choppiness occurs.

You can use Task Manager and Resource Monitor to watch. Use both tools ( run as Admin) but use only one tool at a time.

Start with Task Manager > Performance and use the graphical representations to watch for changes.

Then Resource Monitor.

The first step being to discover what resource(s) are being used, to what extent, and then what is using any given resource.

May take a bit of trial and error to get a sense of it all. Hopefully there will be some viewable change that will, in turn, provide a clue.

Didn't realize that you can turn off viewing signatures, my bad. Added it as requested.

This is what I get in the resource monitor:
I can't really see anything strange except these video encode and decode graphs spiking. On the other hand, I have no experience in video performance to make sense of it.

The video is absolutely fine on the PC monitor but on the TV it's choppy / laggy / low fps.

 

[Ralston18]

Is that Resource Monitor the TV or the monitor?

Make and models - do you have their respective specs?

Some TV's and monitors have their own drivers - any installed?

Also FYI:

(Randomly picked link. You can easily find other similar links for more information and discussion.)

The value being that you may read or see something that explains why (with respect to your setup) the TV is choppy etc. and the monitor is not.

One other thought:

If you right click an empty area of the desktop do you get a menu with the choice "Show more options"?

And by selecting that choice do you get another menu that lists the GPU's Control Panel?

If so, go into the control panel and lookover the various settings and configuration options. Compare monitor and TV. Something could be amiss.

Sorry for replying so late. I was out of comission for a while.

That is the only resource monitor I have. It's the Windows one from the Task Manager.

The monitor is an ASUS TUF Gaming VG27AQL1A and the TV is a Samsung "The Frame" 2019 49"
Up until recently, a few months ago, I had absolutely no problem with stutter and lag when duplicating the image on the TV via HDMI.
I even replaced the HDMI cable again in the last few weeks with a high quality one and still have the same issue.

Drivers are installed for the monitor and the TV doesn't have any as far as I am aware.

I also checked the GPU Control Panel settings up and down, reverted to defaults and the issue persists.

I'm seriously at a loss. Basically, the only thing that I didn't try was to format my PC completely.

I am running a Windows 11 PC that's connected both to my ASUS gaming monitor via display port cable and to my Samsung "The Frame 2019" TV via HDMI cable, and I'm running them in duplicate display mode.

Everything works perfect in the duplicate display mode, I can play games flawlessly, watch videos through any browser without issue and so on.

But when I try playing a video file (i.e. mkv, mp4, literally any) in a video player like MPC-HC or VLC, the video gets extremely choppy on the TV and only on the TV. The monitor displays the video absolutely fine but the output on the TV looks like it's losing frames or it's running in a lower frame rate.

The same happens in other picture modes too, like "extend displays" or "show only on 1 or 2", regardless which display is set as the main display.

The resolution is set at 2560x1440 and the issue occurs regardless if the refresh rate is set to the same value on both displays or not.

Scaling is set to 100 percent on both displays and in the Nvidia Control Panel to perform scaling on "display" on both displays. Changing it to GPU doesn't make the video player issue go away.

GSync doesn't affect the low fps in the video players either regardless if it's on or off.

I've changed three HDMI cables and still nothing.

The only actual change that I managed to force is when I set MPC-HC presentation option in the render settings to "D3D Fullscreen Mode". This kind of resolves the frame rate issue but I get noticable screen tearing in videos.

I'm honestly at my wits end what to do as this issue started randomly and I can't place what might have caused it and continues to cause the issue as I've never had this issue before with the same setup.

Please stick to one thread to keep thoughts on topic.

You have your system set to display 2560x1440 on a 3840x2160 display so somewhere along the line the cpu or gpu is recalculating the screen size which is slowing down performance. You could try setting each display for its native resolution and see if that helps.

Sadly, this doesn't change anything. Even when the native resolutions are set to each display and "extend display" mode is used, video playback is still in a very low framerate.
