Anyone have a 120Mhz refresh rate flat panel TV? Or watch a blue ray on this? HOLY CRAP, I watched a blue ray on one of these TV's recently and the picture is unbelievable. Actually, not in a good way IMHO. We watched irobot and the graphics really stood out and you could tell what was fake/real EASILY. It almost was like watching a movie directly though the camera, completely unprocessed. I don't know how to describe it, but I almost wanted to "de-tune" this feature if it's possible. Anyone else?

 

I've noticed that behviour on mine, it's really awkward feeling so I keep it turned off.

 

^^^ The movie looked like it was filmed on a home movie camera?

 

no it's weird, kinda feels like your looking through the viewfinder of the camera if that makes sense.

 

^ EXACTLY !

Not a home movie camera, but a pro camera that you are looking through the lens with. That's the feeling we all had...

 

Gotcha. I was watching a 120hz TV in Best Buy that had a Blue Ray playing and the picture just seemed like it was almost TOO fluid.

 

Maybe it just takes some getting used too, I might try to log a few hours with it on and see if I can get used to it/if it's worth it.

 

120hz is for sports and video games. Turn it OFF for movies.

I really wish manufacturers were clear about what is for what.

 

Well I feel like a tool now, I'm glad i've had it off all this time.

 

It is NOT for video games. The amount of delay that the processing does makes gaming terrible.

I found this out playing Rock Band, and it was horrible!

 

It most definitely takes some time getting used to 120......the first few movies I saw I felt like it was almost live. I like it now though and I can't watch regular tv's anymore.

 

If it's for sports broadcasted at 720p, then how does it look like? Also, there are 240mhz tv's out now, how does that look like broadcasting 720p TV (sports or movies)?

 

After searching on this phenomenon, and talking to some pro installers, they all say to disable it for BR movies. So hope you're not too used to it.

 

sports are typically shot in 1080i/60fps

All the hertz bs is marketing crap from people. then people get home, dont know how to set up their TVs and then wonder why the image sucks, and then complain is terrible.

 

not everything is broadcast in 720p...depends on the network. Most went 1080i

 

OK here's a stupid question, can an LCD panel have more than one refresh rate? I thought they actually only had a single native refresh rate and dealt with signals that differ from the native rate via multipliers. If this is true, then how can you "turn off" 120 Hz?

My understanding of the original reasoning behind 120 Hz is that it's an even number multiple of 30, 60, and 24 which meant that no matter what the content the TV didn't have to interpolate any fields or frames.

 

To me 120hz looks like 30fps

Movies are shot at lower frame rates and are not supposed to be watched at 30 fps so I disable 120hz for movies.

 

With that said, how does broadcast HD look @ this refresh rate? I don't like it on BR, but wondering how it looks on HD shows/sports?

 

I think I saw this feature at BB. Looked weird and wasn't crazy about it.

 

Mine doesnt do 120...on my friends 52 I dont know if they have it on or off. most likely off. so I cant answer honestly.

 

It is a matter of personal preference if you like it or not.

I have my PS3 hooked up at 1080P, and when I play games, I set my TV (Sony KDL-52W4100) to "Game Mode" which disables all extra processing.

When I watch a Blu-Ray movie, I turn "Game Mode" off which enables "Motion Flow" and "Cinema Flow" which enables the 120Hz processing. This gives the picture an almost 3D feel to it. Like I said, it is a matter of personal preference if you like it or not.

From what I understand, it is not just a refresh rate, but the processing the TV does to generate the extra frames to display.

 

That's what I thought, too.

 

A filmmaker would come to your house and slap you and tell your preference of making his movie look like shitty HD video on your TV is stupid.

 

You are right... I should throw away my HDTV and buy a $100,000 Theater Projector, because thats the way the filmmaker envisioned his movie to be shown...

Damn, I don't think I have a room big enough for that. Guess I have to buy a new house too...

 

I dont understand how you call it "3D feel" it makes a pure HD blue-ray image (stunning) look like your average soap opera (crap). Totally ruins the movie. If anything it should only be used for animated movies.

 

It doesn't do away with interpolation as much as it makes 3:2 pull down unnecessary. The standard 60Hz panels need 3:2 pulldown to display programming that was shot at 24Hz. 3:2 pull down meant that each frame of the 24Hz program was displayed on the 60Hz panel twice in succession with each third frame displayed three times. (eg. F1, F1, F2, F2, F3, F3, F3, F4, F4 etc.) The result was that the picture still seemed a little jittery. A 120Hz panel will display a 24Hz program normally just by displaying each frame for 5 refreshes. Motionflow (Sony's name) tries to go one better by interpolating frames within those 5 refreshes, thereby making the picture even smoother but also introducing "frames" that were not in the original program. A movie shot in 24Hz will look too much like videotape if the motionflow feature is not turned off because the interpolation will approximate the 60Hz nature of videotaped material.

 

You're kinda there...except replace Hz with FPS...movies aren't shot in HZ

That is something for Televisions and Monitors...and really has nothing to do with actual production.

 

My understanding is that with normal 60i video 3:2 pulldown will result in some displayed frames that are a mixture of the even and odd fields from adjacent frames. It's in this sense that I was referring to a TV "interpolating" the content of a frame. With 120 Hz refresh rate, the TV doesn't need to "make things up" in this manner. It simply takes the complete contents of a frame, as it exists in the source material, and displays it multiple times in succession.

 

No problems here, but I have it turned off...only turn it on for sports.

 

I'm an EE but only dabble enough in A/V to be dangerous.

 

I have one and Pirates of the Caribean looks amazing. Alot of movies have scenes that look fake with the Soap Opera effect of 120mhz LCDs.

 

The first time I watch BR(I am Legend) at 1080/24 I thought it was a bit much too. It was soo amazingly clear. You could easily pick out the CGI parts.

 

Experienced the same thing last night with iRobot. TV info showed 60hz and I set the BD player to 24fps and it looked the same.

 

Are you using a PS3 for Blue Ray? I know the PS3 will display it at 60hz or 24fps. Also, I believe your Samsung has something called "film mode" for 24fps, but I have never used it.

 

No, using a Samsung BD-1600. I didn't play around with it too much outside of putting the BD player in 24p mode, which was originally off and the TV in Movie mode.

 

That's just Will Smith's acting you guys are noticing.

 

@ the Will Smith comment


So for movies what would be the ideal refresh rate?

And for games?

 

LoL. I'll try TDK tonight.

 

+1
For movies I think the ideal refresh rate is 24fps. That is the rate at which the movie is displayed at the theater. If you are trying to get your home theater system to replicate as much as possible the movie going experience then 24fps is the number you want. For games, I think you would want as high a refresh rate as possible that can be supported by your hardware.

 

Turned off 120 and its fine. You can switch it on and off on my TV while still watching. Huge difference.
