144hz mat display VS 60hz glossy display

[I know]

Hi,

is it normal that my laptop with a 144hz mat display provides a less smooth image quality in videos compared to my old laptop with a 60hz glossy display?

I mean the video playback is much smoother on the glossy display and on the 144hz mat display it seems that videos judder.

Thank you.

Most video content is 30 or 60 FPS, which isn't evenly divisible by 144. This will sometimes cause stutter (depending on the source and the player).

Lowering your refresh rate to 120Hz when playing back videos should remove the stutter.

If that doesn't remove it, then the other possibility is what you are seeing is due to your 144Hz display having lower GtG (aka pixel transition times) than your 60Hz display. This can make lower framerate content look more juddery due to your 144 display having less inherit motion blur between frames.

That’s indeed correct.

Thank you, but why people I questioned which has the same laptop or a counterpart model(with a144hz display) , told me they don't experience any problem with the videos. They look smooth to them.

I deffently notice the juddering /motion blur on my display

Possibly because not everyone notices the same thing? Just because they say they don't experience it on theirs doesn't necessarily mean it isn't happening on their displays.

Subjectivity counts for a lot when it comes to display "issues," and can depend on individual users' tolerances and sensitivities.

I see,
but is there a way I can make sure it is not a faulty display?
by the way here is one example of a video I see the blur motion

when the plane raising up It's a little juddering

I just watched the clip you linked on my 165Hz display. Yes, the plane (wing in particular) is juddering during the vertical motion in that shot, even when I brought my display down to 120Hz and 60Hz.

It's not your display.

I run across users freaking out about source-specific issues all the time, thinking it's their displays. The source is the most important thing to consider when troubleshooting these occurrences.

It's the source in this case.

If that scene looks any better on your old 60Hz display, it is because, again, that display is blurrier in motion (higher GtG) than your 144Hz display, which masks the inherit judder of low framerate content.

It's simply the cost of displays with better pixel response times; the better the monitor motion clarity, the worse lower framerate sources will look in motion.

Thank you so so much !!!
I'm pretty convinced now that my display is fine thanks to you.
But I don't really understand what do you mean by "source "
and I would be glad If you tell me where I can find videos with a good source.
just to see if it looks any better

But I don't really understand what do you mean by "source "
and I would be glad If you tell me where I can find videos with a good source.

By "source," I mean videos can vary in many different ways:

- Different framerates
- Different resolutions (including, to a lesser degree, whether they're interlaced or progressive; most are the latter nowadays)
- Different capture methods (including panning speed and motion blur level depending on camera shutter configuration)
- Different encoding methods
- Different compression levels

Also, many YouTube montages (like the one you linked), have been pulled from the original footage, and further degraded through editing, re-encoding, and compression. Depending on how this is performed, sometimes even the framerate of the original video can be manipulated or interpolated to a higher one. Often times, amateur video editors will accidentally turn 24 FPS into 30 FPS (etc), causing further stutter or frame-skipping, for instance.

Basically, I wouldn't trust YouTube for reference-quality videos, especially ones that have been manipulated from the original by fans or 3rd parties.

If you want to reference "good" sources, use blu-rays, official digital title streaming, or download the original trailer files directly. There are many 3rd party websites that offer download files of original trailers in full quality, for instance.

If you still see judder in those sources (even with properly configured video playback and monitor Hz), it's simply due to the fact, that again, 24 FPS and 30 FPS content will look more stuttery in motion the less motion blur your display has, which is simply unavoidable.
