There are two main methods. The first is frame interpolation, where the TV itself creates brand-new frames that are sort of hybrids of the frame that came before, and the one that comes after.
This can fool your brain enough that it doesn't blur the image. Depending how aggressive the interpolation is, however, it can lead to the soap opera effect , which makes movies look like ultra-smooth reality TV shows. Some viewers like the effect, but it's generally hated by film buffs and others who pay close attention to image quality. There are different levels of this processing, where a little might reduce motion blur some, and not cause undue harm to the quality of the image.
Or on the other end of the "dial," it's cranked up so that there's even less motion blur, but the movement is hyper-realistic and for many, distractingly unreal. Some TVs let you choose how much of this processing gets applied to the image, others have just a single setting. More on these settings further down. The other alternative is black frame insertion BFI or a scanning backlight. This is where all or part of the backlight of the TV turns off goes black.
This effectively means the image doesn't "hold" in place, so your brain doesn't blur it. Do it poorly, however, and many people will see the image flicker. The light output of the TV also drops, as it's not outputting any light for a period of time. Both of these techniques are what manufacturers use to come up with their "effective refresh rate" numbers. For example, a TV with a 60Hz refresh and a scanning backlight might claim to have an effective refresh rate of A TV with a more elaborate BFI mode, and frame interpolation, might have a claimed effective refresh rate of " It's also possible these features, when enabled, are bothersome over time.
Some people are especially sensitive to a flickering backlight, so you might need to turn these features off. If you're concerned about that, or notice motion blur, it's best to find a TV that actually has a Hz refresh rate. There are two things at play here. The first is simple, and one we've said many times before: don't trust marketing.

But if a manufacturer lists an "effective" refresh rate, the TV's actual native refresh rate is usually half of the advertised effective rate, and other factors—like smoothing and backlight scanning—are sometimes used to multiply refresh rates into higher and higher numbers, such as " Hz. Ultimately, your best bet is to check out unbiased sources like enthusiast forums and professional reviews— here's a good place to start.

As most films are made in 24fps, if you were to watch this on a Hz television, it would add an additional 4 frames in-between the ones that were filmed. Whilst the process is meant to help smooth the picture and minimize any motion blur, it can end up making things look realistic.
One exception was The Hobbit , which was actually filmed in a faster 48fps. It ended up being widely viewed in 24fps, as it was decided that it was a better viewing experience after some initial testing. In most cases, a 60Hz television is going to be absolutely fine for your purpose.
Many of the smart TVs being released today are going to be 60Hz refresh rate. This is just because television networks broadcast at a 50Hz limit in Europe. This is the same case for higher refresh rates too — in the UK, you might see a TV advertised as Hz, but this can play video games at a higher Hz refresh rate just fine. Most televisions that are Hz will have the option for you to reduce the rate back down to 30 or 60Hz if you want to. Most of the new smartphones being released will have a 60Hz display.
This is true for the new iPhone, which was rumoured to have a Hz display, but in the end, all the different variations were released with a 60Hz standard display.
