Fake Refresh Rate Conversion
Samsung Clear Motion Rate vs Sony MotionFlow vs LG Motion Clarity Index

Every TV manufacturer uses marketing numbers to exaggerate the refresh rates of their TVs (learn more about the refresh rate), but thankfully, it isn't quite as nonsensical in 2019 as it used to be. Samsung's Motion Rate, Sony's MotionFlow XR, LG's TruMotion TCL's Clear Motion Index, and Vizio's Effective Refresh Rate aren't accurate numbers for refresh rate, but nowadays most of them are simply double the real thing, making it easy to convert.

The following tables convert fake refresh rates into their real refresh rates. In order: 2019 TVs (North America), 2018 TVs (North America), and 2017 TVs (North America).

Panel Refresh Rate Conversion for 2017 Models for 60Hz Countries (North America)

Fake refresh rates are typically higher than the real refresh rate of the TV, so using them allows manufacturers to market their TVs as being ‘better’ than they are. Since these fake refresh numbers are invented by each company, they are also all different from each other, which makes direct comparison across brands impossible for those who don’t know the conversion to real refresh rates (which generally are not listed).

Samsung Motion Rate (2018-2019)

Samsung's Motion Rate (previously Clear Motion Rate) is pretty straightforward nowadays. For the rare 1080p Samsung TVs still left, the quoted motion rate will be equivalent to the real refresh rate. For 4k TVs, it is simply double the real refresh rate.

2018-19 Models Samsung Motion Rate Real Refresh Rate
Samsung N5300 60 60Hz
Samsung NU6900 120 60Hz
Samsung NU7100 120 60Hz
Samsung NU7300 120 60Hz
Samsung NU8000 240 (except 49") 120Hz (except 49")
Samsung NU8500 240 120Hz
Samsung The Frame 240 120Hz
Samsung Q6FN 240 (except 49") 120Hz (except 49")
Samsung Q7FN 240 120Hz
Samsung Q8FN 240 120Hz
Samsung Q9FN 240 120Hz
Samsung Q900R 240 120Hz

Vizio Effective Refresh Rate and Clear Action (2018)

While Vizio still uses confusing terminology to describe the refresh rate of their TVs, the numbers are easier to translate now than they used to be. Like Samsung, their "Effective Refresh Rate" (which used to be called SPS) is simply double the amount of their real refresh rate. Vizio, however, also uses a confusing number called "Clear Action". It doesn't have much to do with the refresh rate of the TVs and refers to their backlight scanning feature (see image flicker and BFI). The number is almost entirely arbitrary and doesn't mean much.

2018 Models Vizio Effective Refresh Rate Vizio Clear Action Real Refresh Rate
Vizio D Series 4k 60, 120 180 60Hz
Vizio E Series 120 180 60Hz
Vizio M Series 120 360 60Hz
Vizio P Series 240 720 120Hz
Vizio P Series Quantum 240 960 120Hz

Sony Motionflow XR and X-Motion Clarity (2018-2019)

Sony is arguably one of the worst offenders for inflating their refresh rate numbers nowadays, but they've at least started to share the real refresh rate next to their "Motionflow XR" marketing numbers. The numbers don't really mean anything either, it's either 240 or 960. Unlike most other manufacturers, there isn't an easy division you can do, but generally, 240 means 60hz, and anything above that means 120hz. Starting with the 2018 X900F, Sony has also started advertising some high-end LCD models with "X-Motion Clarity" instead of "Motionflow XR". All "X-Motion Clarity" TVs released so far have a 120Hz refresh rate.

2017 Models Sony Motionflow Real Refresh Rate
Sony X750F 240 60Hz
Sony X800G 240 60Hz
Sony X830F 960 120Hz
Sony X850F 960 120Hz
Sony X900F X-Motion Clarity 120Hz
Sony X950G X-Motion Clarity 120Hz
Sony A8F 960 120Hz
Sony Z9F X-Motion Clarity 120Hz
Sony A9F 960 120Hz

LG TruMotion (2018)

LG, like every other manufacturer, uses a marketing term for their refresh rate. It used to go by "Motion Clarity Index", but now it's called TruMotion, which is the same name as their motion interpolation feature (soap opera effect). It's pretty simple to translate since it's just the real refresh rate doubled. In some markets, it is found with a "TM" before the value. For example, a refresh rate of 120Hz would be "TM240". Much like Sony, LG's recently started to share the actual refresh rate of their TVs in parentheses next to the TruMotion value, which is nice. LG OLEDs are a bit different and do not use the TruMotion marketing term, and instead simply state the actual refresh rate.

2018 Models LG TruMotion Real Refresh Rate
LG UK6300 120 60Hz
LG UK6570 120, (except 86" - 240) 60Hz, (except 86" - 120Hz)
LG UK7700 120 60Hz
LG SK8000 240 120Hz
LG SK9000 240  
LG SK9500 240  
LG B8 - 120Hz
LG C8 - 120Hz
LG E8 - 120Hz

TCL Clear Motion Index (2018)

TCL, like most other manufacturers, uses a marketing term instead of the actual refresh rate. Thankfully, TCL simply doubles the actual refresh rate. Some smaller models don't use the Clear Motion Index marketing entirely and simply show the actual refresh rate. As all TCL TVs currently available have 60Hz panels anyway, it doesn't really matter what marketing terms they use.

2018 Models TCL Clear Motion Index Real Refresh Rate
S325 120Hz CMI 60Hz CMI
S425 120Hz CMI 60Hz CMI
S517 120Hz CMI 60Hz CMI
R617 120Hz CMI 60Hz CMI

Conclusion

In the battle for market share, manufacturers try and find creative ways to present existing technologies in new ways. Artificially inflated refresh rates are only one way they are doing this. Thankfully, most manufacturers are becoming more and more transparent in their marketing, so it isn't as difficult to decipher their marketing terms and know what you are actually buying.
