    Hello all.

    I have been searching for this answer all night. What components in a television determine its hertz rate? This is not asking what its motion flow, motion rate, cinemotion, or what ever is. specifically is it a frequency controlled by capacitors and other components or is it directly built into the panel some how?

    It used to be the power frequency, 60 Hz (North America) or 50 Hz (Europe and most of Asia).

    It still is, and its the only part of this particular specification that actually means anything.

    Figures of 200hz and upwards are BS figures pulled from totally arbitrary equivalents of each set's motion interpolation methods.
    Regardless of the set, motion interpolation produces horrible "soap opera" like effects, and it is universally agreed that the best thing about these features is that you can turn them off.

    With these figures, and with the content types available today, hz is approx interchangeable with fps.
    Whats important is that the TV can accept the signals that are commonly sent, so 1080p @ 24/ 50/60 fps, or whatever UHD resolutions and framerates are likely to become common. These will top out at 120fps.

    Ignore all other "hz" figures, they are a nonsense sales tactic.

    From what I understand it's all about the T-CON board or "timing controler" ... 200Hz is no BS number but actually exists (or existed, no new models that do 200(240)Hz refresh rate for 2015).
    The Bodnar input lag tester can actually prove it quite easily as has been pointed out by someone. The difference between the top bar measurement and middle/bottom one are exactly in line with the native refresh rate; a 100 Hz is always running at 100Hz (technically 120Hz), just repeating the same frame instead of creating a new one when interpolation is turned off ...
