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.

For reference, my GPU is a Gigabyte 4070 Ti.
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.

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 TV it's choppy / laggy / low fps.
