How to choose a laptop/mini screen for watching FILMS with no blur

[LaBatya]

Hey guys. I've been struggling with no option to get 24hz on most laptops.

As I understand, it's crucial for watching a movie, furthermore, a panel should somehow have almost 0 latency at that refresh rate (I'm not sure it's possible)

You might ask me — why do I consider such option. Well, I don't want to have a massive computer or monitor, because I travel pretty often. I need a compact solution. AND NO BLUR OF COURSE.

So, what are your thoughts about that? How to choose the right option and be forever happy after?

It's irrelevant. Focus on display quality.
Or even if it is relevant. No one on the consumer side is testing that so whatever.

You cannot be forever happy, considering the limitations you've put up.
One way you could approach this: make a DIY portable display solution.
- Grab a 17.3" 480hz LCD panel with a separate controller board kit
- 3D print the necessary parts for assembly
- Purchase LSFG 3.0, set 20x frame gen mulitplier

Enjoy 24fps content @ 480hz IPS motion clarity with frame generation artifacts.

This may or may not be a adequate solution in your eyes, but it's the only one possible given the constraints.
Ideally, you'd get a 480Hz OLED or wait for the LSFG developer to introduce a higher frame generation multiplier.
Or just don't watch low frame rate content, which tackles this issue at the root cause.

Interesting solution, indeed.

I can't understand something, why is that important to get 480hz to watch 24hz content and use interpolation?

I've checked on an CRT monitor a film on 24hz — it was painful, but super sharp in movement. 24hz and sharp! Isn't that enough for movies?

How I see the solution — I need to find a laptop with good OLED screen and low delay. Then test it somehow, force 24hz or 23.9hz, if it works — good. If it doesn't — well, I should check other one.

The same with an external screen I guess

really need an advice, guys!

My advice is using an integer multiple of 24. 120Hz, 144Hz, 240Hz, 360Hz, 480Hz.

If you want to be able to watch 24, 30, 48 and 60FPS videos without judder, 240Hz matches all of those. 120Hz matches 24, 30 and 60, but not 48.

Thanks for your reply!

As far as I understand, if I have 48 Hz and watch 24 fps content, the image would double in movements; if I have 96 Hz and watch 24 fps content, it would quadruple, and so on.

I've noticed it on all panels I've tested.

I wonder, might it be avoided somehow?

I don't see how that's possible on sample-and-hold displays. I don't see anything like that, unless I enable BFI (OLED) or strobing (LCD.) The only thing I see is judder because some video players aren't accurate enough and miss the correct time to display each frame. Some video players are better than others.

You've already answered the question yourself.
Take a look at this topic: viewtopic.php?f=4&t=13792 (“Flicker-based vs Framerate-based Blur Reduction”)
A CRT would be flicker-based blur reduction.
Any kind of brightness flicker leads to health side effects for almost every living being (incl. animals), hence why framerate-based blur reduction is the only way forward.

I also don't think you fully understand how judder works, this may be beneficial

As RealNc has mentioned, a 240hz or 480hz display should be sufficient for you in terms of eliminating judder.
You can further decrease display-based motion blur by using LSFG 3.0 with the specific multiplier

To be specific:
For a 240hz display you'd use these multipliers depending on the source's frame rate:
24fps => 10x, 30fps => 8x, 48fps => 5x, 60fps => 4x
For a 480hz display:
24fps → 20x, 30fps => 16x, 48fps => 10x, 60fps => 8x

To be as close to a CRT's MPRT as possible on sample & hold, you can go with a 480Hz WOLED or the new 500hz QD-OLED.
Both of these options, however, are not what you requested as you wanted a portable solution. This is why I've mentioned a DIY portable 17.3" 480Hz IPS display solution.
