60hz vs 24FPS on a 100hz tv.

[Mage]

Ok, not sure were to post this, so I'll post it here.

I have a 100hz 32 inch LED tv, Full HD. My bluray player has several settings to play discs, I have it at native, so it doesn't digitally enhance dvd's to much. If I set it at to highest, my dvds become very ugly.

Anyway, sometimes when watching a bluray, you can get a slight shudder during movements. I've been told that this depends on the framerate of the bluraydisc.

Now, on my player I have the choice of setting the visual to 1080p/60hz or 1080p/24fps. What would be the better choice? Or does that depend on the bluray disc as well?

FYI, it's this TV: http://www.p4c.philips.com/cgi-bin/cpindex.pl?ctn=32PFL3258H/12&hlt=Link_Overview&scy=NL&slg=AEN

I've never seen a TV with 100Hz
I've seen 60, 120, 240 for LCD TV.
You have a LCD TV, The LED is only around the Edge of the screen to simulate a brighter picture and to do nothing more than to charge you way more money than necessary.

Set it to 24p if you can.
It may show it, mine does, but until I got a new BD Player, I couldn't select it.

Philips clearly states on the Dutch site that this is a LED tv. Hell, the model was released a year ago, they don't even make LCD tv's anymore.

It says 100hz Perfect Motion Rate, but also something about the 1080p resolution being available at 24, 30, 50 and 60hz. So I'll just try some settings, see what happens.

Did a bit more checking.... I can't figure out if my tv can handle 24fps. It says that it can handle 1080p signals in 24hz, 25hz, 30hz, 50hz and 60hz.
Is 24fps the same as 24hz?
And doesn't that also depend on wether or not the bluray disc is set to 24fps?

 

[Ar-Pharazon]

"fps" is a video speed value, feet per second. Why would the TV have any setting relating to speed?

 

[Kemaiku]

Frames per second

You've honestly never heard that term before?

 

[Ar-Pharazon]

OK, "frames" then, I got the wrong word. It might be something the player can control, but it shouldn't have anything to do with the TV.

There is no such thing as a true LED TV.
It is a LCD display with LED enhancements.

Ah, I see what you mean. Thanks for clearing that up.

Shouldn't all TVs in NTSC-land be 60Hz, 120Hz, 240Hz, and so on?

You know, I honoustly don't know. I'm Dutch, NTSC is US, PAL is European. So I'm a PAL.

Yes, But PAL areas don't even have 60hz as a standard yet.

It says 100hz Perfect Motion Rate

See, that's not even actually 100Hz refresh rate - "Perfect Motion Rate" is basically Philips marketing speak for "we invented our own formula to be able to print a higher number on retail boxes".

All the big manufacturers do it, Samsung for instance calls it "Clear Motion Rate".

PCMag did a pretty good article to help understand refresh rate and how it influences perception when watching TV/Blu-rays and playing video games:

HDTV Refresh Rates Explained: 60Hz, 120Hz, and Beyond

Aha, so that would mean my tv is probably 60hz, and that would be basicly enough for watching tv and Bluray/dvds, since I don't watch sports or play games.

 

[Ar-Pharazon]

Action movies with a lot of movement would get motion blur at 60hz.

I'll try some stuff at 24fps then, see what happens.

And guys, thanks for all the feedback.

 

[KaineMorrison]

No problem. You are welcome.

PAL does have a 60hz standard, it's mostly for compatibility with NTSC and 60hz video game systems. 24fps is to make it the same speed as cinema which runs 24fps, it prevents speed up, shifting the pitch of sound. But 100hz (or 120 or other higher numbers) artificially refresh the screen, to reduce flicker, but it can also cause an odd quality to the video that is too smooth but it also causes tearing in the video or artefacts in the image where it highlights imperfections.
