    It's your display giving you the headache, not BluRay. Adjust your display or get a different one.

    240hz is a spec for displays, and it is mostly stupid. Typically makes the picture worse. Gotta love marketing. And it is for LEDs. I tried LED and didn't like it. Plasma is the way to go if you want the best picture. Plasma is 60hz. And the picture is better at the same price point. Get it?

    If you have an LED, turn OFF 240hz if you can. Sometimes it is labled something else.

    For BluRay viewing set your picture to turn OFF all image processing the TV wants to do. Turn down the brightness and contrast and set the color to Warm (or whatever called to lower blue).

    BluRay is 60hz.

    I lived in a building with over 200 units and the line went down to the basement. We also had cell towers within (figurative) spitting distance. All they could do was tighten the cable connections. It sucked!

    The 240Hz means the LEDs change color faster, not the speed the video is changing frames.

    I don't use 240hz, I know how to turn it off as well, thanks. I was just making an assumption about you, that was wrong. =]

    Gosh, a lot of misinformation.

    240Hz is how fast the LEDs can change color. It's important if the picture is changing rapidly to be able to change the pixel colors rapidly or you will see artifacts. If a pixel needs to change from red to blue faster than the LED can do it, you're going to see the old color for the pixel in a new frame of video. Artifact.

    60Hz is not such a good thing. Movies are shot at 24 frames/second (film). 24 doesn't divide nicely into 60, so they do 3:2 pulldown (in the TV or DVD player) to turn the source into 60Hz. http://www.extron.com/company/article.aspx?id=32pulldown&tab=technology. You will see artifacts of the 3:2 pulldown, especially when there's panning, zooming, or (sports) large variation in the background.

    24 does divide nicely into 120 and 240. No need for pulldown. 480Hz is in the works. The performance gained may not be very noticeable to most human eyes.

    Blue Ray is 24 frames/second. Because the SOURCE is 24 frames/second (film).

    Ah geez.

    You are just adding stuff that is really irrelevant, and some which is wrong.

    In regards to LED TVs many professional TV reviewers have pointed out that 240hz is essentially a marketing gimmick that had little bearing on the quality of the picture reviewed. And many have pointed out that on some sets it makes the picture WORSE. Depends on the implementation. Of course, now most sets are 240hz to keep up with the marketing numbers game. For the vast majority of viewers 120hz is beyond their ability to see. A few very sensitive folks can see the difference. But, other factors are more important in TV quality. Read the reviews.

    IMO, the fixation on marketing the increase in hz so much is to distract from the fact that LED picture quality on anything but very expensive high end sets, is pretty mediocre. The mid-market sets are way better than a couple of years ago, but that is compared to very poor picture quality.

    This whole hz thing is just like the MP wars in cameras once they got past a reasonable level. FAR FAR more important than 8MP vs 12MP is the sensor and the lens.


    BluRay players do output 60hz. Most have a feature to output 24hz, but it must be turned on and only works with supporting TV's.

    AND, that picture will look WORSE unless your TV has this conversion well implemented. My TV takes the 24hz of the Blu Ray output and sends out 96hz. (1080p).

    That work for you?

    Any tips on how to check if my TV, BluRay, and Receiver can do the same?

    I have:
    Sony Bravia 60'' LCD TV
    Onkyo TX-NR609 Receiver
    Panasonic DMP-BDT210 BluRay

    BluRay goes thru receiver then to TV.

    The technology and specs are the same since then.

    Maybe 240Hz is new.

    I dumped Directv. Get NBA League Pass on my laptop. Get latest and greatest movies/Breaking Bad/Game of Thrones via, well, ahem. Anyway, it's such a short list of programs that it's stunning to me I used to drop $60/mo on that crap. Netflix is a bargain though.

    I did miss most of the Olympics, though. I regret that. Would've been nice.

    My next plan is to hook up a PC to my tv. It'll be nice to have that always connected to my home entertainment system for viewing pics, Pandora, listening to music collections and torrenting. I suppose I could do all that in theory through my PS3, but whenever I try it becomes a pain in the ass. There's something solidly simple about a Windows OS, a tv set and an HDMI cable.

    Right. Getting my 60 and 600's mixed up.

    Most signal input to TV's is 60hz with the option for 24fps or 24hz as previously discussed.

    LCD's run the dispaly output at 60, 120 and 240hz and Plasma's at 600hz, but as before, those numbers are misleading in that a crap Plasma at 600hz has a worse picture than a decent LCD at 120hz, and the very best (and $6,000+ LCD's) at 240hz match or exceed the picture quality of 600hz Plasma's. These numbers are just not that illuminating.

    You can try the check for 24fps compatability tips listed in post #6 at this link. If it doesn't work, also try connecting your Blu-Ray direct to the TV, and re-running the test.

    http://forums.plexapp.com/index.php/topic/21870-24-50-60-hz-and-what-it-all-means/

    Also, you can go to AVSforum and searching for you TV and BluRay players and seeing what other owners of those products have to say about how to set it up to work and if it works well. As I said, some products support the feature but don't implement it well, in which case, there is no point in setting it for 24fps if it doesn't improve the picture:
