What's the difference between a 60Hztv and 120Hz tv?

120-60=60

I turn all that motion stuff off. It gives things a Soap Opera effect that I can not stand.

I wouldn't buy a 60hz TV for anything other than a guest room/office/etc... Video games, particularly first person shooters, will look like arse. Plus a lot of companies are using some bullshite way of measuring refresh rates that allows them to claim twice the actual rate (so that 60hz TV is really just a 30hz, 120hz = 60hz). So don't buy a TV labeled less than 120hz.

Refresh rates on TV defined.

This will explain it to you.

Honestly, much of this kind of stuff is quite easily found much quicker by Googling.

Just get a plasma. Mine is 600hz. No blur.

Plasmas don't suffer from motion blur like LCDs, so they don't need higher refresh rates. The problem is, all plasma TV manufacturers also make LCDs. So you're not going to see a big marketing push from any of them saying "No, no, buy our cheaper plasmas because they don't suffer from motion blur (or poor off-axis response, or poor contrast ratios)." With the intense marketing of 120Hz and 240Hz, many consumers assumed plasma was lagging behind, fitting into their erroneous preconceptions that plasma is somehow an "older" technology.

Instead, all three plasma manufactures (LG, Panasonic, and Samsung), had dopted the "600Hz" claim. (I say 'had' because all three have stopped making plasma). Each pixel in a plasma has only two states: on or off. (In that way, they're a completely digital device, unlike LCD, which can still be analog.

Because plasma pixels only have two states, they create different levels of brightness by flashing more or less often. This is where the 600Hz comes in. In the most basic explanation, plasmas break up each frame of video into 10 subfields (60Hz x 10 = 600). If the pixel is supposed to be bright white, it flashes once for each of those subfields. If it's supposed to be 50 percent bright (50 IRE, or medium gray), it flashes for half of those 10 subfields. When it's supposed to be dark, it doesn't flash at all.

So "600Hz" is more or less a marketing thing, but it's not completely untrue. The fact is, plasmas don't suffer from motion blur like LCDs do, so they don't need higher refresh rates, and in fact, are actually 60 Hz.

My tv has 240Hz and I notice a big difference when watching fast moving sports. More Hz= less blur.

The only time I notice the difference between 240hz and lower is during soccer and football punts/long kicks/long throws. Other than that I can't tell.

That's interesting since your cable feed will never provide more that 60 frames per second.

It's not at all "interesting" as you put it, because factually, the interpolation on LCDs of the 60Hz signal improves on and virtually eliminates smear in fast panning motion sports.

It's not interesting as you put it.
