All TVs sold in the UK *should* be able to do both 50Hz and 60Hz. I bought a new TV (£399 Samsung 39" LCD with LED backlighting, can't remember the model number) about a year ago. As long as I connect via HDMI, it can handle 25/50 Hz, 30/60Hz, and 24Hz at 1920x1080, and other frequecies at lower resolutions. Information is difficult to find on reseller websites, but Samsung lists the supported refresh rates/resolutions in the back of the user manuals, which you can find on the Samsung website.

Edit: what she said ^

    whether to go for a later 240Hz 8000 series option, or whether the older 120Hz series are suitable enough.
    Interesting question. I have just looked at the specs for my Sony, and it quotes 800Hz for its "motion flow" processing. :eek: Actually, I am inclined to think that these numbers are all about "specmanship", rather than real technical improvements that are worth having. :rolleyes:

    Does 240Hz produce a better picture than 120Hz, or a worse picture than 800Hz? Who knows! :confused: However, what I would expect is that the quoted numbers are upper limits, and that the TV will use a fixed multiple of the frame rate. From the numbers, the better Samsung can do up to 4x the frame rate for its motion processing, i.e. 240Hz for 60Hz frame rate, and 200Hz for 50Hz frame rate. I would think it more important to match the TV to the frame rate of the video signal, rather than use the frame rate that gives the maximum rate for motion processing. If the frame rate of the video signal is 50Hz, I would expect:

    50Hz frame rate on the TV with 200Hz motion processing is better than
    60Hz frame rate on the TV with 240Hz motion processing

    But what do I know? :D

    As a rule of thumb the manufacturers specs can be halved when it comes to refresh rates. As you touched on above, each manufacturer has its own brand of blur ruduction (Sony has Motion Flow, Samsung has Motion Plus) and they can be used as an excuse to claim higher refresh rates than they are actually capable of. Funnily enough i was reading a good article about it the other day, ill see if i can dig it out.

    Edit: Heres the article (scroll down about half way to the 'Marketing' bit)...

    Just recently bought a new TV, and had to look into some of the stuff discussed here.
    First of, all tvs nowadays support 50hz as well as 60hz input. Generally a TV gets a 60hz rating if it is sold in a ntsc country, like USA, and a 50hz rating for a pal country, like Germany. It's just that different countries are used to different values. Both versions however support both rates.
    This also means that a 120hz TV will support 100hz and vice versa, however these are normally not the input rates. So you won't be able to set you pc to transmit a 1080p 120hz signal, just a 1080p 60hz signal and your TV will then show that at 120hz. Or 24 at 120.
    Your calculations about multiples are therefore not necessary.
    24hz or 23,976hz is another story, though nowadays pretty much all models from the big 4 support these refresh rates as well.
    Motions plus or motion flow hz numbers are just marketing numbers, and describe the frequency with which some of the filters of the TV work and don't correlate to the panel refresh rate, the company's just want to fool you into thinking it does.
    4k vs 1080p, at least in the 6000 Samsung series a 4k TV means a 50/60hz panel and 1080p gives you a 100/120hz panel. As I don't have any 4k material and don't see me getting some in the next few years I went for a 1080p TV (Samsung j6250 (6300 in the us)).
    For reviews of current models I found www.rtings.com to be very good and helpful, they give clear answers on the panel refresh rate, if and how 24p is supported, the input lag if that is of interest and much more. They also give a recommendation on how to set everything up to get the best picture quality.
    Hope I was able to help.

    Good post, thanks for the info. I'd settled on the Samsung 6400 before you'd posted purely because it had a higher clear motion rating. Do you think it makes much of a difference within the range for having this higher spec?

    I have no real need for 3D or any of the other upgrades between the 6300 and the 6400 so if you think the higher CM rating makes hardly any difference id likely go for the same model as you and save the extra cash.

    Are we talking J or JU Series? From what i can see the J6400 is a brazilian model and looks to be identical to 6250/6300(us) but with some features unlocked (3D and PVR which both should be possible on the hardware but are disabled in software), while the JU6400 is a 4K model.

    Neither. The ones that seem readily available in the UK are the UExxH6xxx range (i think UE refers to LED/European and the the letter before the series number refers to the release year, the H is 2014, J is 2015)....

    The H6400 is a 3D TV, but is only 1080p, not 4K. See here for a breakdown of the most common UK models...

    From doing a bit more digging around, it looks like the H6300 doesnt have an optical audio out, which is kind of important to me, so im back to the H6400 i think. If this isnt true of your model, then i can only think its a regional difference if youre outside the UK?

    Im sorry, I thought we were talking about this years model (J Series). I have the J6250, so no idea on the H model.
    I found these two at rtings reviews, but in what way they are identical or not to the uk models, i have no clue.

    This whole different models and different numbers for different countries is just stupid.

    I have 40H6400. It supports 60p, 50p and 24p.
