100Hz LCD's

[Harry88]

I'm looking to purchase a good HD tv. I have been looking at a couple of 40" Sony Bravia TVs. I know that 100Hz is supposed to be better but it image just look unnatural to me. Is this something that you will get used to or doesn't it matter to much for blu-rays?

Every TV has picture modes and setting so you can change the way the picture looks, there is no 100Hz LCD, 120Hz though.

These are the two I have been looking at:

There are if you live in PAL territories, such as Australia where TV and DVD content is ouput at 50Hz.

Doesn't the refresh rate have to be an even multiple of 24, though, since film is shot at 24 fps. What is the film speed across the pond??

[BluLobsta]

Never mind, Wikipedia came to the rescue, it's 25 fps in UK, etc...makes sense lol

"All of these coding methods are in use to some extent. In PAL countries, 25 frames/s formats remain the norm. In NTSC countries, most digital broadcasts of 24 frames/s material, both standard and high definition, continue to use interlaced formats with 2:3 pulldown. Native 24 and 23.976 frames/s formats offer the greatest image quality and coding efficiency, and are widely used in motion picture and high definition video production. However, most consumer video devices do not support these formats. Recently however, several vendors have begun selling LCD televisions in NTSC/ATSC countries that are capable of 120Hz refresh rates and plasma sets capable of 48, 72, or 96Hz refresh.[10] When combined with a 1080p24-capable source (such as most Blu-ray players), some of these sets are able to display film-based content using a pulldown scheme of whole multiples of 24, thereby avoiding the problems associated with 2:3 pulldown or the 4% speed-up used in PAL countries"

That I did not know, what are the differences between PAL and NTSC?

To put it very simply NTSC is output at 29.97(30) fps at a resolution of 720x480, whilst PAL is output at 25fps at a resolution of 720x576.

Is PAL interlaced or progressive?

[Roggster]

PAL is interlaced

Regardless of the PAL vs NTSC differences, what you are refering to is motion enhancement, which is independent of the set's refresh rate and can be turned up/down/off. A set that refreshes in multiples of signal Hz will have less signal processing to do, and 'should' give you a better overall picture. There are countless threads around here discussing motion enhancement.

I have been unable to tell the difference between Auto Motion Plus turned on or off, when on and with settings on the low side does improve motion during fast moving action. It helps out a lot when cameras pan left to right, it just repeats frames a certain number of times.

It actually has to do with how electricity is supplied in european countries. AC or alternating current which means the changes polarity. Their electricity cycles 50 times a second compared to our 60. this is why we have 60 120 and 240. they have 50 100 and 200hz tv's. i belive the 25 fps of blu-ray video also is to make up for their power differences. that is why you can't use some of our electronics overseas. i believe this is all correct but i may be mistaken.

I never knew that, does that go for Australia to?

I ended up going with the KLD40V5500 because it just had a pice drop of $400. That means I can also get a BDP-S360 as well.
