100/60/50/24hz?

[admin_exported]

Hi All,

Sorry for the newb question but i see most TV's are 50/60 hz and if you go higher up the range you can get 100hz but now there is loads of talk about 1080p 24hz surley the higher the hz the better the picture? or as i suspect I am totally missing the point

Thanks in advance

Standard UK TV works on 50Hz, so 100Hz can theoretically give better quality by interpolating extra frames, with particular theoretical benefits for motion smoothness.

I keep saying 'theoretical' because many other factors affect image quality, and 100Hz in itself is no guarantee a set will be better.

Same goes for the US NTSC system, which uses 60Hz as standard, but also gets 120Hz sets.

Blu-ray at 24fps is shown by those sets able to handle the format properly by running at multiples of the24fps rate - usually 96Hz.

Coming next year in profusion - 200Hz sets, and of course 240Hz ones in the NTSC region.

Can you tell I've just spent two weeks here in Korea talking nothing but TV tech?

If 24p is coming to become more common-place, why don't they just sell us 120 and 240hz sets, since both are multiples of 24? Or is there no way of displaying UK 50Hz TV on those?

Because 120/240Hz would have no real advantage over 100/200Hz with a PAL signal, and would indeed require more processing to show PAL.

Let them keep on optimising sets for Europe, I say.

Nice you're back. I had nobody to argue with.

Doesn't mean you can't argue.

You're right but I get him when he's really jet-lagged.
