Default 120Hz LCDs - your opinion?
I just saw a 1080p Sony Bravia LCD with 120Hz Motionflow technology and it blew me away. The last part of Pirates of the Caribbean was running on it and I swear it looked like the action was happening right in front of me outside of a window (TV being the window frame). I've never seen anything like that before. That 120Hz makes a huge difference it seems. Is that thing pretty new? This is the first thing I've seen it though granted I haven't been looking at TVs lately. It honestly blew me away. It looked so real.

BUT, lol if you guys seen it, does it look too real? When you watch a movie you're kinda expecting that little film grain and blurriness. I would love watching Discovery channel like that but a movie....I'm not so sure.

Anyways, what are your thoughts on this?

The displays that use that technology have great color reproduction and contrast but in my personal opinion I do not like the motion at all. Especially for movies I greatly prefer running my projector at 24hz to maintain the actual film speed and have that natural motion blur. To me those displays make it look like the film is video. Productions that are shot in HD video even capture at 24fps to maintain that film-like motion.

I am sure that sports and games could benefit from the 120hz refresh rate but for films I really do not like it, there seems to be a constant push in pull in the motion that looks strange and incorrect.

I've got a 1st gen 120hz TV from Samsung (71 series LCD) and while the motion technology is quite cool to watch in store, it really isn't something you'll want on all the time. How good it looks/works greatly depends on the quality of the input signal. SD and low-bitrate HD channels get some ghosting and weird artifacts when moving/panning quickly. Higher quality HD channels fair a bit better, but there is still some stuttering on my set. Sports games and animated movies look pretty good and almost too real sometimes. Movies and tv shows with suspense and an artsy type feel seem to get ruined since the "atmosphere" changes with auto-motion on.

Maybe they have improved it a bit in the newer models though...

BTW: my set doesn't allow me to use the motion features on my HTPC which is hooked up via DVI/HDMI nor my PS2 via component.

True, but I am sure that can be disabled. On my sony tv set (CRT 100Hz) there was a feature that was called "AI" and it produced an effect in movies like you describe... It really looked weird as the film appeared to sort of speed up a bit then slow down and the motion blur was not really there. I disabled the feature in movies and problem gone[thumbup]

imo, I think 120hz is a waste of money. Movies and animation look unnatural and look like it is moving
fast forward whilst maintaining the same frame rate. The only thing I have seen that looks nice is sports, but for $500 more for something you might be turning off all the time isn't worth it. I prefer a nice 1080p tv with 24p mode. save $500 and buy 25 blu-ray movies.

120hz should be able to display 24p correctly at 5:5 if the TV supoports it.

120 / 24 = 5

Screen refreshes evenly 5 times every frame... so it is doing a true even 24 frames a second. So what the OP was seeing was the 24p mode. As far as I'm aware the screens don't have their refresh lowered to 24hz.
