Hello, i am a newbie in terms of HDTV, i am looking for a new set of tv, Larger and 40 inch to be percise, but when i do research about LED-LCD TV, i saw some have 50hz some are 100hz some are 200 some even more, do you think that 50hz vs 100 hz the diffrence is huge? the price diffrent i saw is quite alot, more than Rm 500 from 50 to 100.
So for all AV enthusiast here, do you think that 100 hz is necessary?

My primary use of tv is for gaming and watching Astro Beyond.
also, Is 3D a gimmick or it is worth the premium. as i know current 3d tv cant do 1080p60 both eye, should i wait for that before getting a 3dtv?

its the vertical scan 50 times per second on each frame if i not mistaken. Can't really see the different with our naked eye but if you go to 200hz... surely there is a different with 50hz.

50hz is the conventional scan for crt tv.. if got money.. go for 100hz above for 40 inch

try to watch movie with some fast moving objects..the difference is there.

IMO, 50hz is considered an 'outdated' spec by now ...

heaps of difference... esp watching football...
50hz can see a "ghosting" effect when you try to follow a flying football...
100hz becomes less noticeable...ball does still look morphed if fast moving...
200hz looks natural

It really depends if its LCD or Plasma.

They refresh differently.

Plasma if the incoming signal is 50Hz (most likely is xxxx/25i), and interlaced (ie broadcast), and the content is live football etc, it would best to refresh it at 100Hz. Anything more is really unnecessary for plasma. 50Hz on a plasma without 100Hz is uncommon, but more than tolerable.

For LCDs, refresh rates are not as simple as repeating the frame 2X or 3X or more. As LCD refreshes differently, there is some form of motion interpolation. Minimum would need it to be 100Hz, even then the motion might not be natural. The problem with going higher refresh rates on a LCD (that does not have a good video processor chip) would me smoother motion but unnatural and motion artefacts near the edges of the people and fast moving edges. In my opinion, unless it has a top notch processor, the motion at 200Hz becomes really video like. Some might argue that broadcast sports is video, but a lot of lcd tvs with super high refresh rates are just weird when it comes to live football and all. Some that do a simple 100Hz seem better (not as smooth but not as video like).
